First Light — Terms of Service

Version: 1.7 Effective Date: September 15, 2026 Originally Effective: August 1, 2026 Last Updated: September 15, 2026

1. Acceptance of These Terms

These Terms of Service (the "Terms") form a binding legal agreement between you ("you" or "User") and Legacy Build Inc. ("Legacy Build Inc.," "we," "us," or "our"), the operator of the First Light service (the "Service").

By creating an account, accessing the Service, clicking "I agree," or using any portion of the Service, you represent that:

  1. You have read and understood these Terms.
  2. You agree to be bound by these Terms and our Privacy Policy.
  3. You are at least eighteen (18) years of age.
  4. You have the legal capacity to enter into these Terms.
  5. If you are accepting on behalf of an entity, you have authority to bind that entity.

If you do not agree to these Terms, do not create an account and do not use the Service.

These Terms contain a binding arbitration provision and a class action waiver (Section 21). These provisions affect your legal rights. Please read them carefully.

2. Eligibility and Account Registration

2.1 Minimum Age

The Service is only available to individuals who are at least eighteen (18) years old. The Service is not designed for, directed at, or intended for use by anyone under 18. We do not knowingly collect information from individuals under 18. If we learn we have collected information from a person under 18, we will delete it.

2.2 Prohibited Jurisdictions

You may not use the Service if you are located in, under the control of, or a national or resident of any country or region subject to comprehensive U.S. economic sanctions administered by the U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC), or if you are on any U.S. government list of restricted or prohibited parties.

2.3 Accuracy of Information

You agree to provide accurate, current, and complete information at registration and to keep your account information updated. You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. You will notify us immediately at questions@seefirstlight.com of any unauthorized use or suspected breach.

2.4 One Account

Each User may maintain one (1) individual account. Business, team, or multi-user accounts are not available at this time and may be introduced subject to separate terms.

3. Description of the Service

First Light is a consumer wellness tool for self-reflection and personal pattern awareness. The Service enables Users to:

  1. Record short text-based and voice-based check-ins capturing their thoughts, feelings, or observations ("Entries") — in the app, through the Chrome extension, or by sending a text message or email to the Service.
  2. Connect compatible health and wearable data sources to provide contextual metrics alongside their Entries. There are two routes: on-device sources (Apple Health on iOS, Google Health Connect on Android), and server-side wearables such as Oura Ring, WHOOP and Fitbit, which are linked directly to the Service rather than through Apple Health. Connecting a server-side wearable also imports readings already stored in that device's account; see our Privacy Policy for how far back that reaches.
  3. Receive AI-generated outputs including daily prompts, pattern observations, morning synthesis messages, and weekly insight reports that identify observational correlations between their Entries and health metrics.
  4. Export their Entries and Service-generated content.

The Service is provided for personal, non-commercial self-reflection use only.

3.1 What the Service Is Not

  • The Service is not a medical device, diagnostic tool, or therapy service.
  • The Service does not provide medical, psychological, psychiatric, or clinical advice.
  • The Service does not establish a therapist-patient, doctor-patient, or other professional relationship.
  • The Service is not a crisis, emergency, or suicide prevention service.
  • The Service does not monitor Users in real time and makes no commitment to detect or respond to any particular content.
  • The Service does not diagnose any mental health condition and is not intended to treat, cure, or prevent any disease.

3.2 Changes to the Service

We may add, modify, suspend, or discontinue any feature of the Service at our discretion. We will use reasonable efforts to notify Users of material changes.

4. Health and Mental Health Disclaimer

THIS SECTION IS CRITICAL. PLEASE READ IT CAREFULLY.

4.1 Not Medical Advice

Information, observations, prompts, insights, reports, song recommendations, and all other outputs generated by the Service (collectively, "AI Outputs") are for informational and self-reflective purposes only. AI Outputs are not medical advice, psychological advice, psychiatric advice, diagnosis, treatment, prescription, or clinical recommendations.

4.2 Consult Qualified Professionals

You should always seek the advice of a qualified healthcare provider, licensed mental health professional, or other licensed clinician with any questions you have about a medical or mental health condition, symptom, treatment, medication, or health goal. Never disregard professional advice or delay seeking it because of something you read, heard, or observed through the Service.

4.3 Observational Framework

The Service surfaces observational correlations — for example, that one metric was observed alongside or followed another. AI Outputs do not establish causation. A pattern identified by the Service is a signal for your own reflection and is not a factual determination about cause and effect.

4.4 No Reliance

You agree that:

  • You will not rely on the Service as a substitute for professional medical, psychological, or psychiatric care.
  • You will not rely on the Service to make any health, medical, or treatment decision.
  • You will not rely on the Service as a crisis intervention resource.
  • Any action you take based on AI Outputs is your sole responsibility.

4.5 Crisis Situations

If you are experiencing a mental health crisis, are having thoughts of suicide or self-harm, or believe you or another person is in immediate danger, stop using the Service and contact emergency services or a crisis resource immediately.

In the United States:

  • 988 Suicide and Crisis Lifeline — call or text 988
  • Crisis Text Line — text HOME to 741741
  • Emergency Services — call 911

Outside the United States, please contact your local emergency services.

The Service includes a limited automated check that runs when you submit a check-in or a message. It compares the words you submit against a list of crisis-related terms. If they match, the Service may display crisis resources. It does nothing else: it sets no flag on your account and changes nothing about how the Service treats you afterwards.

What that check is, stated plainly. It responds to words, not to circumstances. It is not guaranteed to detect distress, self-harm, or any particular content, and it will sometimes respond when nothing is wrong. It does not monitor your account, continuously or otherwise. No person reviews it, no one is alerted, and the Service does not contact emergency services, a third party, or anyone else on your behalf. It involves no clinical assessment and provides no emergency response.

You must not rely on the Service to identify, respond to, alert others to, or intervene in a crisis. If you are in danger, contact emergency services or a crisis line. We do not undertake to monitor your content, to detect every crisis-related statement, or to provide emergency intervention, except to the extent applicable law requires otherwise.

4.6 Pre-existing Conditions

If you have a pre-existing mental health condition, are in active treatment, or are under the care of a mental health professional, we strongly recommend you discuss your use of the Service with your provider before and during use. The Service is not designed to replace or supplement clinical care and may surface content that is emotionally difficult.

4.7 Not Intended for Severe or Acute Conditions

The Service is designed for general wellness and self-reflection by adults without acute or severe mental health needs. The Service is not appropriate for individuals experiencing acute psychiatric crisis, active suicidal ideation, severe depression, psychosis, severe substance use disorder, eating disorders requiring clinical management, or similar conditions. If any of these applies to you, please seek professional care.

5. Account Subscriptions, Billing, and Auto-Renewal

5.1 Subscription Tiers

Access to paid features of the Service is provided through a subscription. Current pricing, subscription terms, and features are described on our pricing page and at checkout. By completing a purchase, you agree to the pricing, renewal terms, and features disclosed at checkout.

Current pricing is published at https://www.seefirstlight.com/#pricing.

5.2 Founding Circle Pricing Promise

Users who purchase a subscription as part of the "Founding Circle" program during the applicable enrollment period receive a perpetual price lock at one hundred ninety-nine United States Dollars ($199.00 USD) per year for so long as their subscription remains continuously active and in good standing ("Founding Circle Price").

The Founding Circle Price is conditional on:

  1. Continuous subscription without lapse or cancellation.
  2. Payment in full on each renewal date.
  3. Compliance with these Terms.

If a Founding Circle subscription lapses, is cancelled, is terminated for breach, or fails to renew for any reason, the Founding Circle Price is permanently forfeited and may not be reinstated. Re-subscription after lapse will be at then-current standard pricing.

The Founding Circle Price does not apply to upgrades, add-ons, new product lines, family plans, team plans, or any product other than the individual subscription purchased during the Founding Circle period.

We reserve the right to increase, decrease, or eliminate the Founding Circle Price for new enrollments at any time. The commitment is to existing Founding Circle members in good standing.

5.3 Standard Pricing

Users who are not part of the Founding Circle, or whose Founding Circle subscription has lapsed, will be billed at the then-current standard subscription price displayed at checkout or on the pricing page.

5.4 Auto-Renewal (Important — Please Read)

YOUR SUBSCRIPTION WILL AUTOMATICALLY RENEW AT THE END OF EACH BILLING PERIOD UNTIL YOU CANCEL.

By purchasing a subscription, you authorize us (and our third-party payment processors) to automatically charge your payment method at the beginning of each renewal term for the then-applicable subscription fee, plus any applicable taxes and fees.

  • Founding Circle members: Renews annually at the Founding Circle Price of $199.00/year.
  • Standard subscribers: Renews at the end of each billing period at the then-current standard price — $349.00/year for annual plans, or $39.00/month for monthly plans, as of the effective date.

You will be notified of upcoming renewals and any price changes in accordance with applicable law. Renewal pricing is disclosed at the time of initial purchase and at each renewal reminder.

5.5 How to Cancel

You may cancel auto-renewal at any time by:

  1. Visiting your account settings within the Service and selecting "Cancel Subscription"; or
  2. Emailing us at questions@seefirstlight.com at least one (1) business day before your renewal date.

Cancellation stops future renewals. Cancellation does not, by itself, entitle you to a refund of fees already paid (except as provided in Section 6 — Refund Guarantee).

After cancellation, you will retain access to paid features through the end of the then-current billing period, after which your account will revert to free-tier access (if available) or lose paid feature access.

5.6 Payment Methods

We currently accept payment via credit and debit cards processed through Stripe. We may add additional payment methods (including Apple in-app purchases and Google Play billing) in the future. Purchases made through Apple or Google platforms are subject to those platforms' terms, refund policies, and cancellation mechanics, which may differ from these Terms.

5.7 Taxes

Prices are in U.S. Dollars and exclude applicable taxes. You are responsible for all applicable taxes, including sales tax, VAT, GST, and similar. Where required by law, we or our payment processors will collect and remit taxes.

5.8 Failed Payments

If a payment fails, we may retry the charge, suspend your access, or terminate your subscription. You are responsible for keeping your payment information current.

5.9 Price Changes

For Founding Circle subscribers in good standing, the Founding Circle Price will not be increased during continuous active subscription.

For all other subscribers, we may change subscription prices upon at least thirty (30) days' prior notice. Continued use of the Service after the effective date of a price change constitutes acceptance of the new price.

5.10 Free Trials and Promotions

From time to time, we may offer free trials, promotional pricing, or discounts. These offers are subject to their specific terms disclosed at enrollment and may be discontinued at our discretion. A User may be eligible for only one (1) free trial per account unless we expressly indicate otherwise.

6. Refund Guarantee

6.1 365-Day Unconditional Refund

We offer a 365-day unconditional money-back guarantee on the initial annual subscription purchase. If, for any reason, you are not satisfied with the Service within three hundred sixty-five (365) days of your initial purchase, you may request a full refund of the purchase price.

There is no minimum usage requirement. You do not need to provide a reason.

6.2 How to Request a Refund

To request a refund, email questions@seefirstlight.com from the email address associated with your account within 365 days of your initial purchase. Include your account email and the approximate date of purchase.

6.3 Processing

Refunds will be processed to the original payment method via Stripe (or the applicable payment processor) within seven (7) business days of refund approval. Depending on your card issuer, it may take an additional business cycle to appear on your statement.

6.4 Scope of the Guarantee

The 365-day guarantee applies to the initial annual purchase only. It does not apply to:

  • Renewal payments (which are governed by Section 6.5 below).
  • Monthly standard subscriptions. Monthly subscribers are not charged a year in advance and may cancel at any time to stop future charges; the 365-day guarantee is specific to the annual up-front purchase.
  • Add-ons, gifts, or non-subscription purchases.
  • Accounts terminated by us for breach of these Terms.

6.5 Renewal Refunds

Because renewals are automatic, you may request a refund for a renewal charge within thirty (30) days of the renewal date, provided you have not made substantial use of the Service during that renewal period.

6.6 What Happens to Your Account After a Refund

If you receive a refund under the 365-day guarantee, your account will be closed and your access to the Service will end. Your data will be handled as described in Section 13 (Termination) and our Privacy Policy.

7. User Content

7.1 Definition

"User Content" means all content you submit to, record on, upload to, or create using the Service, including:

  • Text-based Entries.
  • Voice recordings and their transcriptions.
  • Responses to prompts, tags, and structured selections.
  • Exported reports annotated or modified by you.
  • Any other content you submit.

7.2 Ownership

You retain all ownership rights in your User Content. Legacy Build Inc. does not claim ownership of your User Content.

7.3 License to Legacy Build Inc.

You grant Legacy Build Inc. a worldwide, non-exclusive, royalty-free, fully paid-up license to host, store, reproduce, process, transcribe, analyze, transmit, and display your User Content solely to the extent necessary to provide, maintain, secure, troubleshoot, and improve the Service for you.

This license:

  1. Terminates when you delete the User Content or close your account, subject to the retention periods described in our Privacy Policy and Section 13.
  2. Does not permit us to sell your User Content.
  3. Does not permit us to share your User Content with third parties except as described in our Privacy Policy (which includes disclosures to service providers such as Anthropic, our AI provider, Stripe, and infrastructure providers, solely to operate the Service).
  4. Does not grant us rights to use your User Content to train artificial intelligence or machine learning models, except as described in Section 9.

7.4 Responsibility for User Content

You are solely responsible for your User Content. You represent and warrant that:

  1. You own your User Content or have all rights necessary to submit it.
  2. Your User Content does not infringe any third party's rights.
  3. Your User Content does not violate any law.
  4. Your User Content does not contain protected health information of any other person that you are not authorized to share.

7.5 Voice Recordings

Voice recordings submitted to the Service are processed as follows:

  • Transcription: Voice recordings are transcribed to text using our transcription provider (currently OpenAI's Whisper API).
  • Audio retention: By default, the audio is deleted as soon as it has been transcribed, and we keep only the transcript. If you turn on "Keep my voice recordings" in settings, audio you record from then on is kept until you delete the check-in it belongs to, or your account. Turning the setting off again stops us keeping new recordings; it does not remove the ones we kept while it was on. Our Privacy Policy and Consumer Health Data Privacy Policy describe this in full.

8. AI-Generated Outputs

8.1 Definition

"AI Outputs" means content generated by the Service's artificial intelligence features, including daily prompts, pattern observations, morning synthesis messages, weekly insight reports, recommended actions, song recommendations, and chat responses.

8.2 Ownership of AI Outputs

AI Outputs generated specifically for you based on your User Content are your property to the extent permitted by law. You are free to use, share, export, print, and modify AI Outputs for your personal use.

8.3 Ownership of the System

Legacy Build Inc. retains all right, title, and interest in and to:

  • The underlying Service, software, models, prompts, templates, algorithms, and systems that generate AI Outputs.
  • Generalized learnings, aggregated patterns, and non-identifying insights derived from Service operation.

8.4 No Warranty on AI Outputs

AI Outputs are generated by machine learning systems and may be:

  • Incorrect, incomplete, inconsistent, or outdated.
  • Based on pattern recognition that does not reflect actual causation.
  • Sensitive to small variations in your input.

You acknowledge that AI Outputs are suggestions for reflection, not facts, advice, or recommendations. The disclaimers in Section 4 apply in full.

8.5 Third-Party AI Providers

The Service uses third-party AI infrastructure, including (currently) Anthropic's API (for generated AI Outputs) and OpenAI's API (for voice transcription and for the text embeddings that power search). Your User Content may be processed through these providers' systems solely to provide the Service to you. Under these providers' standard API terms, your User Content is not used to train their models.

9. Data, Privacy, and AI Training

9.1 Privacy Policy Incorporated

Your use of the Service is also subject to our Privacy Policy, available at https://www.seefirstlight.com/privacy, which is incorporated into these Terms by reference.

9.2 No AI Model Training on User Content

Legacy Build Inc. does not use your User Content to train artificial intelligence or machine learning models. We do not sell, license, or provide your User Content to any third party for training purposes.

9.3 Aggregated and De-identified Data

Legacy Build Inc. may create aggregated or de-identified data derived from User Content and Service usage. Aggregated or de-identified data:

  • Does not identify you.
  • May be used to operate, improve, and evaluate the Service.
  • May be used in anonymized form in marketing materials (e.g., "X% of users observed pattern Y").
  • Will not be sold to third parties.
  • Will not be shared with external research partners without additional user consent.

9.4 Health Data

Health-related data you connect to the Service (including via Apple Health) is treated as sensitive personal information. Our handling of this data is described in our Privacy Policy and complies with applicable laws, including, where applicable, Washington's My Health My Data Act.

Depending on your jurisdiction, you may have rights to:

  • Access your personal data.
  • Correct inaccurate personal data.
  • Delete your personal data.
  • Export your personal data in a portable format.
  • Opt out of certain processing.
  • Withdraw consent.

To exercise these rights, contact privacy@seefirstlight.com. We will respond within the timeframes required by applicable law.

9.6 Third-Party Data Sources

When you connect third-party data sources (such as Apple Health, Google Health Connect, Oura, WHOOP, or Fitbit), you authorize those providers to share data with us, and you authorize us to receive and use that data as described in these Terms and our Privacy Policy. For server-side wearables this authorization covers readings recorded before you connected, as described in our Privacy Policy. Your use of those third-party services is governed by those services' terms.

10. Acceptable Use

You agree not to:

  1. Use the Service in violation of any law or regulation.
  2. Attempt to reverse engineer, decompile, or extract the source code of the Service (except as permitted by applicable law).
  3. Interfere with, disable, or circumvent the Service's security features.

  5. Use the Service to harass, threaten, or harm any person.
  6. Upload malware, viruses, or harmful code.
  7. Attempt to access another User's account or data.
  8. Resell, redistribute, or provide Service access to third parties.

  11. Attempt to derive training data or model weights from the Service.
  12. Impersonate any person or misrepresent your affiliation.
  13. Use the Service for any commercial purpose without our express written consent.

Violation of this Section 10 may result in immediate suspension or termination of your account without refund.

11. Intellectual Property

11.1 Our IP

All intellectual property rights in and to the Service — including software, code, models, prompts, designs, trademarks (including "First Light," "Legacy Build," and associated logos), content, AI system architecture, and documentation — are owned by Legacy Build Inc. or its licensors.

11.2 Limited License to You

Subject to these Terms, Legacy Build Inc. grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Service for your personal, non-commercial use.

11.3 Feedback

If you send us suggestions, ideas, or feedback about the Service, you grant us a perpetual, irrevocable, worldwide, royalty-free license to use that feedback without obligation to you. You represent that any feedback you submit is your own and does not infringe any third party's rights.

11.4 Copyright Complaints (DMCA)

If you believe content on the Service infringes your copyright, send a notice compliant with 17 U.S.C. § 512(c)(3) to our designated agent at legal@seefirstlight.com.

12. Third-Party Services

The Service integrates with third-party services, including:

  • Anthropic (AI processing)
  • OpenAI (voice transcription and search embeddings)
  • Stripe (payment processing)
  • Twilio (text-message capture and SMS notifications)
  • Mailgun (inbound email capture)
  • Resend (outbound email)
  • Apple (HealthKit, in the future App Store)
  • Google (in the future, Play Store)
  • Supabase (data infrastructure)
  • Railway (hosting for the wearable data service we operate)
  • Wearable and health-data providers (Oura, WHOOP, Fitbit and similar, linked directly; and Apple Health / Google Health Connect on your own device)

Your use of these third-party services is governed by their own terms and privacy policies. We are not responsible for the acts or omissions of third-party providers. Legacy Build Inc. disclaims all liability arising from third-party services, including outages, data errors, or changes to their terms.

13. Termination

13.1 Termination by You

You may terminate your account at any time via account settings or by emailing questions@seefirstlight.com.

13.2 Termination by Legacy Build Inc.

We may suspend or terminate your account at any time, with or without notice, if:

  1. You materially breach these Terms.
  2. Your payment fails.
  3. Your use of the Service creates legal, security, or operational risk.
  4. We are required by law.
  5. We discontinue the Service.

13.3 Effect of Termination

Upon termination:

  • Your access to the Service will end.
  • Export before you terminate. You may download a complete copy of your User Content at any time while your account is active, using the export tool in Settings. Because termination is immediate and permanent, you should export your User Content before terminating — we cannot recover it afterwards. The deletion confirmation screen will remind you and offer the download at that point.
  • Upon termination, your User Content is permanently deleted immediately, except:
    • Aggregated or de-identified data (which does not identify you).
    • Financial records, tax records, and other data we are legally required to retain.
    • Backups: where backup copies are maintained, deleted information is removed or rendered inaccessible according to our documented backup-rotation process.

13.4 Refunds on Termination

  • If you voluntarily cancel outside the 365-day guarantee period (Section 6), you will not receive a refund of fees paid. Your access continues through the end of the current billing period.
  • If we terminate your account for your breach, you will not receive a refund.
  • If we terminate your account because we are discontinuing the Service or for reasons unrelated to your conduct, we will issue a pro-rata refund for the unused portion of your current billing period.

13.5 Survival

The following sections survive termination: Sections 4 (Disclaimer), 7.2–7.4 (Ownership and Responsibility for User Content), 8.3 (System Ownership), 9 (Data), 11 (IP), 14 (Warranties), 15 (Liability), 16 (Indemnification), 21 (Arbitration), 22 (Governing Law), and any provision that by its nature should survive.

14. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. TO THE MAXIMUM EXTENT PERMITTED BY LAW, LEGACY BUILD INC. DISCLAIMS ALL WARRANTIES, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, AND UNINTERRUPTED OR ERROR-FREE OPERATION.

Without limiting the foregoing, we do not warrant that:

  • AI Outputs will be accurate, useful, or reliable.
  • Health data integrations will be uninterrupted or error-free.
  • The Service will detect any particular content, including crisis-related content.
  • The Service is suitable for any particular person or purpose.
  • The Service will meet your expectations.

Some jurisdictions do not allow the exclusion of certain warranties. In those jurisdictions, the above exclusions apply to the maximum extent permitted by law.

15. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW:

15.1 Excluded Damages

LEGACY BUILD INC., ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, SUPPLIERS, AND LICENSORS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING LOST PROFITS, LOST DATA, LOSS OF GOODWILL, BUSINESS INTERRUPTION, OR PERSONAL INJURY, ARISING OUT OF OR RELATED TO THE SERVICE, THESE TERMS, OR AI OUTPUTS, REGARDLESS OF LEGAL THEORY, EVEN IF LEGACY BUILD INC. HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

15.2 Cap on Liability

LEGACY BUILD INC.'S TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF: (A) THE AMOUNT YOU PAID LEGACY BUILD INC. IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM; OR (B) ONE HUNDRED UNITED STATES DOLLARS ($100.00 USD).

15.3 Basis of the Bargain

You acknowledge that these limitations are a fundamental basis of the bargain between you and Legacy Build Inc. and apply even if a limited remedy fails of its essential purpose.

15.4 Jurisdictional Limits

Some jurisdictions do not allow the exclusion or limitation of certain damages. In those jurisdictions, our liability is limited to the greatest extent permitted by law.

16. Indemnification

You agree to indemnify, defend, and hold harmless Legacy Build Inc. and its affiliates, officers, directors, employees, and agents from and against any claim, liability, damage, loss, and expense (including reasonable attorneys' fees) arising out of or related to:

  1. Your breach of these Terms.
  2. Your User Content.
  3. Your violation of any law or third-party right.
  4. Your use of the Service.
  5. Your reliance on AI Outputs.

Legacy Build Inc. reserves the right to assume exclusive defense of any matter subject to indemnification, in which case you agree to cooperate.

17. Changes to the Terms

We may modify these Terms from time to time. When we do:

  1. We will update the "Last Updated" date at the top.
  2. For material changes, we will provide at least thirty (30) days' notice via email or in-app notification.
  3. Your continued use of the Service after the effective date of changes constitutes acceptance.
  4. If you do not agree to the updated Terms, you must stop using the Service and may cancel your subscription.

Corrections take effect when we publish them, and every one is logged.

Sometimes a change here corrects something these Terms said inaccurately, rather than changing what we do. Waiting thirty days to publish a correction would mean leaving a statement we already know to be wrong in front of you for thirty more days, which helps nobody. So corrections take effect on publication.

A change is a correction only if it leaves all four of these untouched: what we collect, how we use it, who receives it, and how long we keep it. A change that alters any of them is not a correction and carries the thirty days’ notice above. Narrowing what we do, or describing it more accurately, is the only thing this paragraph covers.

Every correction is recorded in the Revision History at the end of these Terms, naming what the previous version said and why it was wrong. That record is the check on this paragraph: it is what stops a correction from being made quietly.

For Founding Circle members, changes to these Terms do not modify the Founding Circle Pricing Promise (Section 5.2), which is preserved per its stated conditions.

18. Communications

By creating an account, you consent to receive:

  1. Transactional communications (billing, account security, service updates, legal notices) via email.
  2. Service-related communications (product notifications, pattern alerts, weekly reports) via email and, if you provide a phone number and opt in, via text message (SMS), per your notification preferences.
  3. Marketing communications (only if you opt in), which you may unsubscribe from at any time.

If you opt in to text-message (SMS) notifications, message and data rates may apply, and message frequency varies with your settings and how often you check in. You can stop them at any time by replying STOP to any message or by turning them off in your notification settings, and you can reply HELP for help. Your phone number and your text-message opt-in consent are not shared with third parties or affiliates for marketing purposes.

19. Export Control

You represent that you are not located in, and will not access or use the Service from, any jurisdiction subject to comprehensive U.S. economic sanctions, and that you are not on any U.S. government restricted or denied party list.

20. Assignment

You may not assign these Terms without our prior written consent. Legacy Build Inc. may assign these Terms freely, including in connection with a merger, acquisition, reorganization, or sale of assets.

21. Dispute Resolution — Binding Arbitration and Class Action Waiver

PLEASE READ THIS SECTION CAREFULLY. IT REQUIRES YOU TO ARBITRATE DISPUTES WITH LEGACY BUILD INC. AND LIMITS THE MANNER IN WHICH YOU CAN SEEK RELIEF.

21.1 Informal Dispute Resolution

Before filing any arbitration, you agree to attempt to resolve the dispute informally by emailing legal@seefirstlight.com. Legacy Build Inc. will attempt to resolve the dispute by email or phone within sixty (60) days.

21.2 Binding Arbitration

If the dispute is not resolved informally, you and Legacy Build Inc. agree to resolve any dispute, claim, or controversy arising out of or relating to these Terms or the Service through binding individual arbitration administered by JAMS under its Streamlined Arbitration Rules and Procedures (for claims under $250,000) or Comprehensive Arbitration Rules and Procedures (for larger claims), as applicable.

  • Location: Sheridan, Wyoming, or by videoconference at either party's election.
  • Language: English.
  • Arbitrator's authority: The arbitrator has exclusive authority to resolve all disputes, including arbitrability.
  • Federal Arbitration Act: This arbitration agreement is governed by the Federal Arbitration Act (9 U.S.C. §§ 1–16).

21.3 Class Action Waiver

YOU AND LEGACY BUILD INC. AGREE THAT ANY DISPUTE MUST BE BROUGHT IN AN INDIVIDUAL CAPACITY, NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, COLLECTIVE, OR REPRESENTATIVE PROCEEDING. THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PERSON'S CLAIMS OR PRESIDE OVER ANY FORM OF REPRESENTATIVE OR CLASS PROCEEDING.

If this class action waiver is held unenforceable, the entire Section 21 is null and void, and the parties agree that the dispute will proceed in court rather than in arbitration.

Revision History

Version 1.7 — effective September 15, 2026

Quiet Mode has been removed from the product, and so from these Terms.

Section 4.5 said that when the crisis check matched, the Service "may make the following week quieter" if you had turned Quiet Mode on. That feature was removed on September 15, 2026 (see the Privacy Policy's revision history for the same version). Section 4.5 now says what the check does, which is one thing: it may display crisis resources. Everything else in that section, including what the check is not and what you must not rely on it for, is unchanged.

How this version is classified under the change-notice commitment. A correction: it alters what we say to match what we now do, and narrows nothing and widens nothing about your rights or obligations under these Terms. No advance notice was owed in any case: First Light has no users yet, so there is nobody whose agreement predates this version.

Version 1.6 — effective September 15, 2026

Section 18 said less about text messages than the carriers require us to say, and less than was true.

The paragraph on text-message notifications named the cost ("message and data rates may apply") and the way out (reply STOP), and stopped there. It now also says that message frequency varies with your settings and how often you check in, that you can reply HELP for help, and that your phone number and your opt-in consent are not shared with third parties or affiliates for marketing purposes. The last of these has always been how First Light works; it was simply not written down, and the US toll-free messaging registry requires it to be, in these Terms and in the Privacy Policy, before a business number may text anyone at all.

Nothing about what we do has changed. This version states three things that were already true.

How this version is classified under the change-notice commitment. A correction: it alters what we say, not what we do, and narrows nothing and widens nothing. No advance notice was owed in any case: First Light has no users yet, so there is nobody whose agreement predates this version.

Version 1.5 — effective September 9, 2026

Section 4.5 described the crisis feature in a way that did not match what the software does.

It said the feature was "provided as a courtesy" and that it "does not create any duty of care on our part". Outside counsel advised removing both. "As a courtesy" is the language that describes a gratuitous undertaking, which is precisely the kind a court can still hold you to. And whether a duty of care exists is decided by a court, not asserted by us in our own Terms — in the situation the sentence was written for, such clauses are unenforceable in much of the world.

More to the point, the old wording said the feature "is not a crisis monitoring service" while the software does run an automated check on submitted content. Our Privacy Policy now describes that check in detail (Section 2.8), so a categorical denial here would have contradicted it.

Section 4.5 now describes the limited thing the check actually is: it compares your words against a list of terms; it responds to words rather than circumstances; it will miss things and will sometimes respond when nothing is wrong; nobody reviews it; nobody is alerted; and the Service does not contact emergency services or anyone else on your behalf. We keep the statement that detection is not guaranteed, and the statement that you must not rely on the Service in a crisis. Those are accurate, and they do the work the removed sentences were meant to do.

Nothing about the software changed in this version. This corrects what we said about it.

No advance notice was owed for this change: First Light has no users yet, so there is nobody whose agreement predates it.

How this version is classified under the change-notice commitment. Most of what changed here is a correction as newly defined: it alters what we say, not what we do. The exceptions are three, and all three narrow what we do rather than widen it — Quiet Mode now requires your consent before it can happen at all, its record is now deleted rather than kept, and an internal score was removed. Nothing here expands what we collect, how we use it, who receives it, or how long we keep it, so no renewed consent is required. And no advance notice was owed in any case: First Light has no users, so there is nobody whose agreement predates this version.

Version 1.4 — effective September 7, 2026

We replaced the company that used to sit between your wearable and us.

Until now, health data from a connected device reached us through Terra, a separate health-data aggregation company. Terra received your readings, normalized them, and passed them on. We have replaced Terra with Open Wearables — health-data software that we run ourselves. The practical effect is that one fewer company receives your health data: what used to be an outside service is now software under our own control, and no aggregation provider sits in front of us any more.

The software runs on servers provided by Railway, which is now listed as a service provider in the same way our other hosting and database providers are. Railway stores the data for us; it is not a health-data company and does nothing with it.

Nothing about what we collect, how long we keep it, or what we do with it has changed. The third-party provider list in Section 11 names Railway in Terra's place.

No advance notice was owed for this change: First Light has no users yet, so there is nobody whose agreement predates it. Once the Service has users, material changes carry thirty days' notice as described in these Terms.

Version 1.3 — effective September 5, 2026

  • Voice recordings had the default backwards. Section 7.5 said audio is kept for the life of your account unless you switch to a "transcript only" setting. The software has done the opposite since July 2026: audio is deleted as soon as it has been transcribed, and keeping it is something you turn on yourself, with a setting called "Keep my voice recordings." No "transcript only" setting exists. Both privacy policies already described this correctly, so these Terms were the document out of step. Section 7.5 now matches them, including what turning the setting off again does: it stops us keeping new recordings; the ones kept while it was on stay until you delete the check-ins they belong to, or your account.

On the 30 days' notice promised in Section 17. No notice was given for this change, and none was owed, for the same reason recorded under Versions 1.1 and 1.2: First Light still has no users. The only accounts in existence belong to the operator, testing the Service before launch, so there is no one to notify. We are recording that here rather than leaving it to be inferred. The Section 17 commitment stands unchanged and applies in full from the first real user onward.

Version 1.2 — effective September 2, 2026

  • How wearables actually connect. Section 3 described wearables as connecting "via Apple Health" — as though Oura, WHOOP and Fitbit reached us through HealthKit. They do not: those are server-side integrations linked directly to the Service, and Apple Health / Google Health Connect are a separate, on-device route. Both privacy policies had always described it correctly, so these Terms were the document out of step. Corrected in Sections 3 and 9.6, and in the third-party provider list in Section 11.
  • History is imported when you connect a wearable. Sections 3 and 9.6 now say that linking a server-side wearable also brings in readings already stored in that device's account, and point to the Privacy Policy for how far back that reaches. Section 9.6 in particular is where you authorize that sharing, so it is where the scope of the authorization belongs.

On the 30 days' notice promised in Section 17. No notice was given for these changes, and none was owed, for the same reason recorded under Version 1.1: First Light still has no users. The only accounts in existence belong to the operator, testing the Service before launch, so there is no one to notify. We are recording that here rather than leaving it to be inferred. The Section 17 commitment stands unchanged and applies in full from the first real user onward.

Version 1.1 — effective August 28, 2026

Consolidates every change made since Version 1.0 took effect on August 1, 2026:

  • Deletion timing. Corrected a promise of up to 30 days to export your data before deletion; deletion is immediate, and the export is available beforehand rather than during a wait.

On the 30 days' notice promised in Section 17. Section 17 commits us to 30 days' advance notice before a material change takes effect. No such notice was given for the changes above, and none was owed: First Light had no users during this period. The only accounts in existence belonged to the operator, testing the Service before launch, so there was no one to notify. We are recording that here rather than leaving it to be inferred.

The Section 17 commitment stands unchanged and applies in full to every version from this one onward.

Version 1.0 — effective August 1, 2026. Initial published policy.
