Important: In‑App Purchase Verification Fix (2025‑11‑12)

We improved purchase verification and restore logic. If paid features are locked after updating:

  1. Open Settings > Purchase and tap “Restore purchases”
  2. Ensure you are signed in with the same Google/Apple account used for purchase
  3. Restart the app after restore completes
  4. If it still fails, update to the latest app version and try again
  5. Contact support if the issue persists

Note: Cross‑platform restore (Android ↔ iOS) is not supported by the stores.

Face Detection (Google ML Kit)

  • Detection runs on-device; photos and face data are not sent to servers
  • On first use, an ML model may be downloaded to your device from Google (no photo data is sent)
  • Ensure camera permission is granted to use camera features

If face detection does not start, connect to the internet once to allow model download, then retry.
