• Local backup files can be created and shared
• Backup files contain your shopping data and preferences
• No cloud storage is used - all data remains under your control

Security Measures

• Encryption of data in transit and at rest
• Regular security assessments
• Access controls and authentication
• Secure coding practices

5. Your Rights and Choices

6. Children's Privacy

Cart Tracker is not intended for children under 13. We do not knowingly collect personal information from children under 13. If you believe we have collected information from a child under 13, please contact us immediately.

7. International Users

Cart Tracker stores all data locally on your device. The only data transmitted is barcode information to third-party product lookup services to retrieve product details.

8. Third-Party Services

Product Database APIs

We use third-party services to look up product information when you scan barcodes. These services receive only the barcode number to provide product details like name, price, and brand information.

Google Play Services

The app uses Google Play Integrity API to verify app authenticity and prevent tampering. This helps ensure the security and integrity of the application.

9. Data Retention

We retain your information for as long as necessary to provide our services. Specifically:

• Local Data: Remains on your device until you delete the App or clear its data
• Backup Data: Backup files you create are retained until you delete them
• Usage Data: Anonymous usage statistics may be retained for app improvement purposes

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by:

• Posting the updated policy in the App
• Sending a notification through the App
• Updating the "Last Updated" date at the top of this policy
