Terms of Service

Last updated: June 20, 2026

These Terms of Service (“Terms”) are a legal agreement between you and Grow Labs LLC (“Grow Labs,” “we,” “us,” or “our”) governing your use of the Safr mobile application and related services (the “Service”). By downloading, accessing, or using Safr, you agree to these Terms. If you do not agree, do not use the Service.

Please read Section 14 carefully. It contains a binding arbitration agreement and a class-action waiver that affect how disputes between you and Grow Labs are resolved. If you are a US resident, this affects your legal rights, and you have 30 days to opt out. Nothing in these Terms waives any right you have under your local law that cannot be waived.

1. Eligibility

You must be at least 16 years old to use Safr in the United States, 18 in the United Kingdom, and the applicable digital-consent age (13 to 16) in the EU/EEA (13 elsewhere), or older where your local law requires. Safr is intended for an adult and older-teen audience, not for children. By using the Service, you represent that you meet the minimum age, that you can form a binding contract with us, and that you will comply with these Terms and all applicable laws.

2. The Service

Safr is a period and cycle tracker. You log your period and related information, and Safr uses your history to predict your next period, fertile window, and ovulation and to track the symptoms you log. Optionally, with your permission, Safr can use temperature data from Apple Health to help refine these estimates.

Not medical advice. Not a contraceptive. Not a medical device. Safr is an education and cycle-tracking app. It is not a contraceptive and does not prevent pregnancy. Never rely on it to avoid or to achieve pregnancy. It is not a medical device and is not a substitute for professional medical advice, diagnosis, or treatment. No fertility-awareness method is 100% accurate. Always consult a qualified healthcare professional for contraception, family planning, or any medical question, and for a medical emergency contact your local emergency services.

3. Use at your own risk

Our goal is to make cycle information useful to you, but the Service cannot and does not guarantee any health outcome. Any prediction, estimate, fertile window, or insight is provided for general, informational purposes and may be inaccurate. Your use of the Service, and any decision you make in reliance on it, including any decision related to pregnancy or contraception, is at your sole risk. The Service is not intended to serve the same purpose as a medical or scientific device or a healthcare provider.

4. Information for minors

Content in the Service is provided for general educational purposes only. It does not incite, induce, or promote any sexual behavior among minors and is not directed to any particular person. We make reasonable efforts to keep the content factual and age-appropriate for users who are old enough to use the Service.

5. Your account

You are responsible for the information you provide, for activity under your account, and for keeping your device and any credentials secure. Notify us promptly of any unauthorized use. The Service is intended for your personal, individual use.

6. Connected services

If you choose to connect a third-party service such as Apple Health or Oura, you authorize Safr to import the data you approve. Your use of any third-party service is also governed by that provider's own terms and privacy policy, and you can disconnect it at any time. Safr is not responsible for third-party services and is not affiliated with, endorsed by, or sponsored by their providers, including Ōura Health Oy.

7. Subscriptions, billing, and cancellation

Safr offers auto-renewing subscriptions. The price, billing period, and how to cancel are shown in the app before you purchase. Please review them carefully.
Payment is charged to your Apple App Store account at confirmation of purchase.
Subscriptions renew automatically at the same price unless you cancel at least 24 hours before the end of the current period. We will tell you in advance, through the App Store, of any price change, and a price change takes effect only at the start of the next period.
If your plan includes a free or reduced-price trial, it automatically converts to a paid subscription when the trial ends unless you cancel before then.
Deleting the Safr app does not cancel your subscription. You manage and cancel your subscription in your Apple App Store account settings. Cancellation takes effect at the end of the current billing period.
Except where the law requires otherwise, payments are non-refundable, and refund requests are handled by the App Store under its policies. Where the App Store's terms conflict with these Terms regarding purchase, billing, cancellation, or refunds, the App Store's terms govern.

8. AI features

Safr's optional AI chat and photo analysis are powered by a third-party provider (OpenAI). The first time you use either feature, we ask for your explicit agreement before anything is sent, and you can decline. AI responses are generated automatically, may be inaccurate or incomplete, and are not medical advice. Do not rely on them for medical decisions.

9. Acceptable use

You agree not to:

Use the Service unlawfully or in violation of these Terms.
Reverse engineer, interfere with, or attempt to gain unauthorized access to the Service.
Copy, resell, or commercially exploit the Service without our permission.
Upload content that is unlawful or infringes others' rights.

10. Intellectual property and your content

The Service, including its software, design, and content, is owned by Grow Labs LLC and protected by intellectual-property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to use Safr for your personal, non-commercial use. You retain ownership of the data and content you provide, and you grant us only the limited license needed to operate and provide the Service to you.

11. Disclaimers

The Service is provided “as is” and “as available,” without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, secure, or that any estimate, insight, or window it produces is accurate or reliable. Some jurisdictions do not allow certain warranty exclusions, so some of these may not apply to you.

12. Limitation of liability

To the maximum extent permitted by law, Grow Labs LLC and its affiliates will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss arising from your reliance on the Service, including any decision related to pregnancy, contraception, or health. Our total liability for any claim relating to the Service will not exceed the greater of the amount you paid us for the Service in the twelve months before the claim or fifty US dollars (USD 50). Some jurisdictions do not allow certain limitations, so some of these may not apply to you. Nothing in these Terms limits liability that cannot be limited under applicable law.

13. Termination

You may stop using Safr and delete your data at any time. We may suspend or terminate access if you violate these Terms or to protect the Service. Provisions that by their nature should survive termination, including Sections 11, 12, 14, and 15, will survive.

14. Dispute resolution, arbitration, and class-action waiver (US residents)

This Section 14 applies to you if you are a resident of the United States. It does not waive any right you have under your local law that cannot be waived, and it does not apply to the extent prohibited by the law that applies to you.

a. Informal resolution first. Before starting an arbitration, please email us at chenglin@growlabsllc.com with a description of your dispute. We will try in good faith to resolve it for 60 days. Many disputes can be resolved this way.

b. Binding arbitration. If we cannot resolve a dispute informally, you and Grow Labs agree that any dispute arising out of or relating to these Terms or the Service will be resolved by binding individual arbitration, administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, rather than in court, except as stated below. The Federal Arbitration Act governs this Section. Judgment on the award may be entered in any court with jurisdiction.

c. Class-action and jury waiver. You and Grow Labs agree to bring claims only in an individual capacity, and not as a plaintiff or class member in any class, collective, or representative action. The arbitrator may not consolidate more than one person's claims. You and Grow Labs waive any right to a jury trial.

d. 30-day right to opt out. You can opt out of this arbitration agreement within 30 days of first accepting these Terms by emailing chenglin@growlabsllc.com with your name and a clear statement that you opt out of arbitration. Opting out will not affect any other part of these Terms.

e. Exceptions. Either party may bring an individual claim in small-claims court, and either party may seek injunctive relief in court to protect its intellectual property. If the class-action waiver in (c) is found unenforceable as to a particular claim, that claim (and only that claim) will proceed in court, and the rest of this Section still applies.

15. Governing law

These Terms are governed by the laws of the State of Delaware and applicable US federal law, without regard to conflict-of-laws rules. Subject to Section 14, disputes will be resolved in the courts located in Delaware. If you are a consumer in the United Kingdom, the EU/EEA, or another region whose law gives you mandatory rights, you keep those rights and may bring proceedings in your local courts; nothing in these Terms removes protections that the law of your country of residence gives you.

16. Changes to the Service and Terms

We may modify the Service or these Terms. When changes are material, we will update the “Last updated” date and, where appropriate, notify you in the app. Continued use after changes take effect means you accept the updated Terms.
