3D QR does not require user accounts. Saved scenes, selected themes, and point balances are stored locally on the device.

Links entered by the user are processed in the app to generate QR scenes. At this time, the app does not require a personal account or attach those links to a hosted user profile.

3D QR uses Google AdMob rewarded ads to grant save points. During ad delivery, Google may process device identifiers, usage data, or other ad-related signals according to its own policies.

The app requests photo-library access only when the user chooses to save an exported video. Saved videos remain on the user device and, when permitted, in the user photo library.
