4. Data Storage and Security

All sleep detection data and app settings are stored locally on your device. We do not operate servers that store your personal data. We implement appropriate technical and organizational measures to protect your information against unauthorized access, alteration, disclosure, or destruction.

5. Your Privacy Choices

5.1 Advertising

• You can opt out of personalized advertising by adjusting your device settings
• iOS: Settings > Privacy & Security > Apple Advertising > Personalized Ads (OFF)
• You can purchase the Pro version to remove all advertisements

5.2 App Tracking Transparency

On iOS 14.5 and later, we will request your permission before tracking. You can change your tracking preferences at any time in your device settings.

5.3 Motion & Fitness Access

You can revoke the App's access to motion and fitness data at any time through your device settings. Note that this will prevent the sleep detection feature from working.

6. Children's Privacy

Our App is rated 9+ and is not directed to children under 13. We do not knowingly collect personal information from children under 13. If we become aware that we have collected personal information from a child under 13, we will take steps to delete such information.

7. International Data Transfers

As we do not collect or transmit personal data to servers, there are no international data transfers. Third-party services (like AdMob) may transfer data internationally according to their own privacy policies.

8. Your Rights

Depending on your location, you may have certain rights regarding your personal information, including:

• The right to access your personal information
• The right to correct inaccurate information
• The right to delete your information
• The right to restrict or object to processing
• The right to data portability

Since all data is stored locally on your device, you can exercise these rights by managing your device settings or deleting the App.

9. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by updating the "Last Updated" date at the top of this Privacy Policy. Changes are effective when they are posted on this page.

10. Data Retention

All data is stored locally on your device and is retained until you delete the App. No data is stored on our servers. Third-party services may retain data according to their own policies.

11. California Privacy Rights

If you are a California resident, you have specific rights under the California Consumer Privacy Act (CCPA). Since we do not sell personal information and do not collect personal identifiers, most CCPA requirements do not apply to our App.

12. European Union Users

If you are located in the European Union, you have rights under the General Data Protection Regulation (GDPR). Our legal basis for processing motion data is your consent, which you provide when granting permission to access motion and fitness data.
