• Advertising tracking IDs: Android Advertising ID and Apple IDFA for displaying in-app advertisements
• Coarse location information: we only collect this data after you actively grant location permission to the app

You can disable ad tracking through your device privacy settings, but some reading synchronization functions may be restricted after closing tracking permissions.

However, no data transmission over the public internet can achieve 100% absolute security.

User data will only be stored within the minimum time required to complete the collection purpose and fulfill legal retention obligations. Once the data loses service value, all stored records will be permanently deleted or fully anonymized.
