Xsension ("we," "us," or "our") operates the Xsension mobile application (the "App"). This Privacy Policy explains how we collect, use, store, and protect your personal information when you use our App.

2. How We Use Your Information

3. Third-Party Services and AI Processing

We share data with the following third-party services only as necessary to provide the App's functionality. Before any data is shared with OpenAI, you are shown an in-app disclosure and must explicitly consent.

OpenAI (Third-Party AI Service)

Xsension uses OpenAI's GPT-based API to generate your analysis. Specifically, the following data is sent to OpenAI over an encrypted HTTPS connection when you request an analysis:

OpenAI processes this data solely to generate the text response (scores, feedback, and suggestions) that is returned to Xsension and displayed to you. OpenAI processes this data in accordance with their Privacy Policy and Business Terms. By default, data submitted through the OpenAI API is not used to train OpenAI's models. OpenAI represents that it maintains industry-standard security protections for data submitted through its API that are equivalent to or stronger than our own. Xsension does not send OpenAI any of your account information (email, password hash, device tokens, subscription details) or any identifying metadata beyond what is needed for the analysis itself.

Amazon Web Services (AWS)

Your account data is stored in AWS RDS (a managed PostgreSQL database), hosted in the United States. Photos are transmitted through our server for processing but are not permanently stored on our servers. AWS provides data protections equivalent to or stronger than our own.

Apple

Subscription and in-app purchases are handled entirely by Apple through StoreKit and the Apple Push Notification service (APNs). We receive subscription status information and deliver notifications through APNs, but never receive your payment details. Apple's handling of purchase and notification data is governed by Apple's own privacy policies.

We do not sell, rent, or share your personal information with advertisers, data brokers, or any other third parties not listed above.

4. AI-Generated Content and Its Limitations

Xsension uses an AI language model (OpenAI's GPT models) to generate your scores, feedback, and suggestions. You should be aware that:

A detailed list of trusted external organizations where you can learn more about these topics is available in the App under Profile → Legal → Sources & Medical Disclaimer.

5. Data Storage and Security

6. Data Stored on Your Device

The App stores the following data locally on your device:

This local data is not accessible to other apps and is removed when you delete the App, sign out, or delete your photos from the Profile screen.

To exercise any of these rights or for questions, contact us at founder.xsension@gmail.com. We will respond to your request within 30 days.

9. Children's Privacy

Xsension is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. Users who indicate they are under 18 may use the App with certain features restricted (such as photo uploads). If you believe a child under 13 has provided us with personal information, please contact us at founder.xsension@gmail.com and we will delete that information promptly.

10. Analytics and Tracking

Xsension does not use any third-party analytics SDKs, advertising frameworks, or user tracking tools. We do not track your activity across other apps or websites. We do not serve advertisements. Xsension does not collect data in a way that requires App Tracking Transparency (ATT) disclosure.

11. Push Notifications

Push notifications are entirely opt-in. On your first use of the App (or the first time you open the App after an update that introduces notifications), you will be asked whether you want to enable notifications. You can also manage individual notification categories in the Profile → Notifications screen:

You can disable notifications at any time from within the App or from your device's system settings. When you sign out or delete your account, your device token is removed from our servers.

12. International Users

Xsension is operated from and hosted in the United States. By using the App, you understand and agree that your information will be transferred to, stored, and processed in the United States.

13. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically. Continued use of the App after changes constitutes acceptance of the updated policy.
