Yellow Teeth

Terms of Use

Last updated: 18 May 2026

These Terms of Use ("Terms") govern your use of the Yellow Teeth mobile application (the "App") provided by Jorge Castillo Pérez ("we", "us"). By installing or using the App you agree to these Terms.

1. The App

The App provides an AI-generated teeth whitening routine based on a photo you supply. Generated routines are educational suggestions only and are not medical or dental advice. The App is not a substitute for examination, diagnosis, or treatment by a licensed dental professional. Consult your dentist before starting any whitening routine, especially if you have gum disease, sensitivity, or restorations.

2. Eligibility

You must be at least 13 years old (or the minimum age of digital consent in your country, whichever is higher) to use the App.

3. Subscriptions and free trials

4. License

We grant you a personal, non-exclusive, non-transferable, revocable license to install and use the App on Apple devices you own or control, subject to these Terms and to Apple's standard Licensed Application End User License Agreement (apple.com/legal/internet-services/itunes/dev/stdeula), which is incorporated by reference. In the event of a conflict, these Terms control unless prohibited by Apple's EULA.

5. Your content

You retain ownership of photos you submit. By submitting a photo, you grant us a limited license to process it via our AI providers solely to generate your routine. We do not retain the photo on our infrastructure after analysis. See the Privacy Policy for details.

6. Acceptable use

7. Disclaimers

The App is provided "as is" and "as available" without warranties of any kind, express or implied, including but not limited to merchantability, fitness for a particular purpose, and non-infringement. Results from following any routine vary by individual and are not guaranteed.

8. Limitation of liability

To the maximum extent permitted by law, we are not liable for any indirect, incidental, consequential, special, or punitive damages, or any loss of profits or revenue, whether incurred directly or indirectly. Our total liability for any claim arising out of or relating to the App will not exceed the amount you paid us in the 12 months preceding the claim, or USD 50, whichever is greater.

9. Termination

You may stop using the App at any time. We may suspend or terminate access if you violate these Terms. Provisions that by their nature survive termination (e.g., disclaimers, liability limits) will continue to apply.

10. Changes

We may update these Terms from time to time. Continued use of the App after a change constitutes acceptance of the new Terms. Material changes will be communicated via the App or App Store update notes.

11. Governing law

These Terms are governed by the laws of Spain, without regard to its conflict of laws principles. Any dispute will be resolved in the competent courts of Spain, unless mandatory consumer protection laws of your country of residence provide otherwise.
