AR Rubik's Cube Privacy Policy
Summary
- You don't need an account.
- The camera is used only to read your cube and track your hands. Camera images are processed on your phone and are never saved or uploaded.
- The app shows ads from Google AdMob, which collects device data such as the advertising ID. Where the law requires it, you are asked for consent first.
- We don't sell your data, and we (the developer) don't receive any of it.
Camera
The app asks for camera permission so it can scan your cube's faces, follow your turns and draw the 3D guide over the camera view. Recognition runs entirely on your phone using OpenCV and Google MediaPipe. Camera frames are not recorded, stored or sent anywhere.
What stays on your phone
Your best times, lesson progress and app preferences are stored in the app's private storage on your phone. They are not sent to us or anyone else. If Android backup is turned on for your Google account, Android may include them in your device backup, which Google stores under your control.
Advertising (Google AdMob)
The app shows banner, interstitial and rewarded ads (for example to unlock a hint or an auto-solve). These ads are served by Google AdMob, which may collect and process:
| Data | Why |
|---|---|
| Advertising ID and device identifiers | Ad delivery, frequency capping, measurement and, if you allow it, personalised ads |
| IP address and approximate location derived from it | Ad delivery and fraud prevention |
| App interactions with ads, crash and performance data | Measurement, fraud prevention and diagnostics |
If you are in the European Economic Area, the UK or Switzerland, the app shows Google's consent message before ads load, and you can change your choice at any time from Privacy settings at the bottom of the menu. You can also reset or delete your advertising ID in your phone's Google settings. Learn more in how Google uses information from apps that use its services and Google's privacy policy.
Deleting your data
Uninstall the app to remove all of its data from your phone. Because we hold no copy, there is nothing to request from us.
Children
The app is not directed at children under 13 and does not knowingly collect personal information from them.
Changes and contact
If this policy changes, the new version will be posted on this page with a new effective date. Questions: chenaizhong87@gmail.com.
