Terms of Service

Last updated: June 13, 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.

1. Eligibility

You must be at least 13 years old to use Safr, and the fertility-awareness features are intended for adults. By using the Service, you represent 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 consent, Safr can use temperature data from Apple Health or a connected wearable (such as Oura) to help refine these estimates.

Not medical advice; not a contraceptive. Safr is an education and cycle-tracking app. It is not a contraceptive and does not prevent pregnancy — never rely on it to avoid 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. For contraception or medical advice, talk to a healthcare professional.

3. Your account

You are responsible for the information you provide, for activity under your account, and for keeping your login credentials secure. Notify us promptly of any unauthorized use.

4. Oura connection

Connecting Oura is optional and requires your explicit authorization through Oura’s sign-in. Your use of Oura’s services and devices is also governed by Oura’s own terms and privacy policy. You may disconnect Oura at any time. Safr is not affiliated with, endorsed by, or sponsored by Ōura Health Oy.

5. Subscriptions and payments

Safr offers auto-renewing subscriptions. Pricing and options are shown in the app before you purchase.
Payment is charged to your Apple App Store or Google Play account at confirmation of purchase.
Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period.
You manage and cancel subscriptions in your App Store or Google Play account settings.
Except where required by law, payments are non-refundable; refund requests are handled by the app store.

6. 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.

7. Intellectual property

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 you provide.

8. 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, or that any estimate, insight, or window it produces is accurate or reliable.

9. 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 amount you paid us for the Service in the twelve months before the claim. Some jurisdictions do not allow certain limitations, so some of these may not apply to you.

10. Termination

You may stop using Safr and delete your account 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 will survive.

11. 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.

12. Governing law

These Terms are governed by the laws of the State of Delaware and applicable U.S. federal law, without regard to conflict-of-laws rules. Disputes will be resolved in the courts located in Delaware, unless your local law gives you the right to bring proceedings elsewhere.
