Cubory — Privacy Policy
Last updated: November 6, 2026
This policy explains what data Cubory ("the app") handles. The app is published by Yabin Alejandro Lagunes Cuevas, trading as The Alchemist Code ("we"), who is responsible for your data. Contact: [email protected].
The short version
- There is no account. We never ask for your name, email or password.
- Your solves, sessions, scrambles and settings are stored only on your device. We do not upload them anywhere.
- The app does not use your location, contacts, camera or microphone, and it works fully offline. Scrambles are generated on your phone.
- The app shows ads and uses analytics and crash reporting. Those services, run by Google, collect some technical data, described below.
Data stored on your device
Your sessions (name, event, when you created or archived them), your solves (time, scramble, +2 or DNF penalty, date and optional note), your statistics and your settings (inspection, hold-to-start, sound, haptics, cube theme). They stay on your phone.
- Backup file and CSV export: the app creates these files only when you ask. You decide where to save them and who to share them with. We never receive them.
- Android backup: if backup to your Google account is turned on in your phone's settings, Android may include the app's data in your device backup so it comes back when you move to a new phone. Android makes that backup and stores it encrypted in your Google account. We have no access to it.
You can erase everything at any time in Settings › Delete all my data. Uninstalling the app also removes it from the phone.
Data collected by third-party services
| Service | What it collects | Why |
|---|---|---|
| Google AdMob (ads) | IP address (used to estimate approximate location), Android advertising ID and app set ID, interactions with ads and the app, performance diagnostics | Showing ads, measuring them, preventing fraud |
| Google Analytics for Firebase | App-instance ID, advertising ID, approximate location derived from a masked IP address, screen views, sessions and purchase events | Understanding how the app is used |
| Firebase Crashlytics | Crash stack traces, device metadata at the time of a crash, app state, an installation identifier | Finding and fixing crashes |
| Firebase Remote Config | Country, language, time zone, OS and app version | Adjusting app settings remotely |
| Google Play Billing (Android) / Apple App Store, StoreKit (iOS) | Payment details and your purchase | Processing your Premium subscription or one-time purchase (we never see your card) |
On iOS, the Google services above can use device identifiers, and Analytics can collect the vendor identifier (IDFV). The advertising identifier (IDFA) is available only with tracking permission. These technical identifiers are separate from the records you enter in the app.
None of these services receives your solves or sessions. All of this data is encrypted in transit. Each provider handles it under its own privacy policy:
- Google: https://policies.google.com/privacy
- Apple: https://www.apple.com/legal/privacy/
- How Google uses data from apps that use its services: https://policies.google.com/technologies/partner-sites
Your choices
- Ad personalization (EEA, UK, Switzerland): the app asks for your consent before showing personalized ads, and you can change your choice anytime in Settings › Ad privacy options.
- Advertising identifiers: on Android, you can reset or delete the advertising ID in Android settings under Privacy › Ads. On iOS, you can allow or deny tracking when asked and change that choice in iOS Settings. Denying tracking prevents access to IDFA; the other app or vendor identifiers described above can still be used.
- Notifications: On Android, optional subscription reminders can be scheduled before renewal. You can deny or revoke notification permission in Android settings.
- Premium removes all ads.
Your rights
You can ask us about your data or to delete it by writing to [email protected]. Because the app has no account and your data stays on your phone, we hold nothing that identifies you; deleting your data in the app removes it for good.
Children
The app is not directed at children under 13 and we do not knowingly collect data from them.
Changes
If this policy changes, the new version will be posted at this address with an updated date.
