Terms of Service

Last updated: April 18, 2026

These Terms govern your use of the Know Your Skin mobile application (the "app"). By creating an account or using the app you agree to these Terms. If you do not agree, do not use the app.

Important: the app provides general skincare information and is not medical advice. See section 4 below.

1. Eligibility

You must be at least 13 years old (or the minimum age in your country) to use the app. If you are under the age of majority where you live, you represent that your parent or guardian has reviewed and agreed to these Terms on your behalf.

2. Your account

You are responsible for keeping your login credentials secure and for all activity under your account. Notify us promptly if you believe your account has been compromised.

3. Acceptable use

You agree not to:

4. Health disclaimer

The app provides general information about skincare routines, ingredients, and products. It is not medical advice and is not a substitute for consultation with a qualified dermatologist or physician. Skin reactions vary from person to person; always patch- test new products and stop use if you experience adverse effects. We make no warranty that product recommendations are safe or effective for your specific situation.

5. AI-generated content

The app uses third-party AI services to analyze photos and ingredients. AI output can be wrong or incomplete. Treat it as a starting point, not a diagnosis.

6. Content you submit

You retain ownership of photos, journal entries, and other content you submit. You grant us a limited, worldwide, royalty-free license to store, process, and display that content solely to operate the app for you. You may delete your content at any time.

7. Third-party products and retailers

The app may display products from third-party brands and retailers, and may include affiliate links. We are not responsible for their accuracy, availability, safety, or the terms of any purchase you make through external links.

8. In-app purchases and subscriptions

If the app offers paid features, they are sold through the App Store or Google Play and are subject to the billing terms of those platforms. Subscription renewals, refunds, and cancellations are handled by the respective store.

9. Termination

You may delete your account at any time from inside the app or via our account deletion page. We may suspend or terminate access for violation of these Terms, fraud, or abuse of the service, or for legal reasons.

10. Disclaimer of warranties

The app is provided "as is" and "as available" without warranties of any kind, express or implied, to the maximum extent permitted by law. We do not warrant that the app will be uninterrupted, error-free, or free of harmful components.

11. Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect, incidental, special, consequential, or punitive damages arising from your use of the app. Our total liability for any claim arising from the app will not exceed the greater of (a) the amount you paid us in the 12 months before the claim and (b) USD 50.

12. Apple-specific terms

If you use the iOS version of the app, you acknowledge that these Terms are between you and us only, not with Apple, and Apple is not responsible for the app or its content. Apple is a third-party beneficiary of these Terms and has the right to enforce them.

13. Changes

We may update these Terms from time to time. Material changes will be reflected by an updated "Last updated" date; continued use after the update constitutes acceptance.

14. Governing law

These Terms are governed by the laws of your country of residence, except where another jurisdiction is required by applicable law.
