Privacy policy
In short: One-Rule Tactics does not collect, send or share any of your personal data. Your progress and settings are stored only on your own device.
This policy covers the One-Rule Tactics app for Android, developed by DangMua Studio (“we”).
Data stored on your device
So you can pick up where you left off, the app keeps the following in its private storage on your device:
- Progress: stars per level, the level in progress, the islands you have opened and your best run on each level.
- Settings: sound, music, vibration, language, theme, timer and warning mode.
This data is never sent to us or anyone else. It is deleted when you uninstall the app or clear its data in Android Settings.
If you turn on Google backup on your device, Android may include this data in a backup in your own Google account and restore it when you reinstall. That backup is managed by Google under your settings; we cannot access it.
What we do not do
- No accounts and no sign-in.
- No ads and no in-app purchases.
- No analytics, tracking or automatic crash reporting, and no third-party SDKs that collect data.
- No access to your location, contacts, photos, camera, microphone or advertising ID.
App permissions
- Internet: used only to fetch the latest version of the game’s information pages (support, privacy and about) from studio.dangmua.com when you open them. These requests carry no personal data. The game itself plays fully offline.
- Vibration: for light haptic feedback while you play. You can turn it off in the game’s Settings.
Information pages
The game shows its support, privacy and about pages inside the app. When you open one and are online, the game asks studio.dangmua.com for its latest version and keeps a copy on your device, so the pages also work offline. This website uses no cookies and no analytics; its host (Cloudflare) may keep technical logs such as IP addresses to run and secure the service.
Children
The game is suitable for all ages but is not directed at children under 13. Because we collect no data from anyone, we collect none from children.
Changes
If this policy changes, we will update this page and the effective date at the top.
