RubiCute: Privacy Policy
Last updated: 2 November 2026
RubiCute ("the app") is made by Bui Dinh Dan ("we", "us"). This policy explains what information the app uses, why, and the choices you have. It covers the iOS and Android apps.
Summary
- No accounts and no sign-in. We never ask for your name, email, contacts or precise location.
- The camera is used only on the Camera Scan screen to read your cube's sticker colours. Camera images are processed on your device and are never stored, recorded or uploaded.
- Your progress (lessons, stars, timer history, settings) is saved on your device.
- The app shows an occasional full-screen ad between sessions through Google AdMob.
- The app has no in-app purchases, no server and no analytics SDK of its own.
- We do not sell your information.
Data Collection & Analytics
Camera
When you use Camera Scan, the app reads the colours of nine small spots in the live camera preview to work out your cube's stickers. This happens entirely on your device, frame by frame, and the images are discarded immediately. Nothing from the camera is saved or sent anywhere. You can always use Manual Input instead and never grant camera access.
Stored on your device
Your XP, rank, practice streak, Academy stars and best times, timer history and settings are stored only on your device. They are never sent to us. Deleting the app deletes them, and Settings → Reset clears your progress at any time.
Advertising
The app shows an occasional full-screen ad when you finish a solution, a lesson, a practice drill or a Free Play solve, through Google AdMob. To show and measure ads, Google may collect device and advertising identifiers, approximate location derived from your IP address, ad interactions and diagnostic data.
Analytics
The app does not use Google Analytics, Firebase Analytics or any other analytics SDK.
Notifications
If you allow reminders, the app schedules local notifications on your device (keeping your practice streak, a nudge after a few days away). They are created on the device; no push service or server is involved.
Spoken hints
If you turn on spoken move hints, the move names are read aloud by your device's built-in text-to-speech. Nothing is recorded.
Third-Party SDK Disclosures
| Service | What it receives | Why | Policy |
|---|---|---|---|
| Google AdMob | Device and advertising identifiers (IDFA on iOS only if you allow tracking), IP address (used to estimate your region), device and app information, ad interactions and diagnostics. | To show and measure ads and prevent fraud. | Privacy policy |
| Apple App Store / Google Play | Download records handled by the store. | To distribute the app. | Apple, Google |
Your choices: in the EEA, UK and Switzerland the app asks for your consent through Google's consent form before any ad loads, and you can change it any time under Settings → Ad privacy. On iOS the app asks for permission before using your advertising identifier (App Tracking Transparency); you can change this in iOS Settings → Privacy & Security → Tracking. On Android you can reset or delete your advertising ID in your device settings. Camera access can be turned off in your device's settings at any time.
Children's Privacy (COPPA)
The app is not directed at children under 13, and we do not knowingly collect personal information from children under 13, in line with the U.S. Children's Online Privacy Protection Act (COPPA) and similar laws. Ads are configured as not child-directed and limited to content suitable for teens. If you are a parent or guardian and believe your child has provided personal information through the app, email [email protected] and we will delete it.
Account & Data Deletion
The app has no accounts, so there is no account to delete. To delete your data:
- In the app: Settings → Reset clears your progress and timer history.
- On your device: uninstall the app. This removes everything the app stored.
- Advertising data: data collected by Google AdMob is controlled by Google. You can reset your advertising ID in your device settings or manage it at https://myadcenter.google.com.
Security
Ad traffic uses encrypted connections (HTTPS/TLS). Camera images never leave your device.
Changes
If this policy changes, we will update this page and the date at the top.
