Summary
Dose Doubler does not collect, transmit, or share personal data. There is no account, no login, no analytics SDK, and no advertising SDK in this version of the app.
What is stored on your device
Your game progress is saved locally using iOS UserDefaults and never leaves your device. This includes:
- Best score and highest tier reached
- Daily Challenge streak and today's best score
- Cross-run stats (runs played, total merges, longest chain, tier distribution)
- Sound, haptics, theme, and difficulty preferences
- Whether you've seen the in-game tutorial
Uninstalling the app erases all of this data. We have no copy of it.
Game Center
Dose Doubler integrates with Apple's Game Center. If you sign in to Game Center, your scores and achievements may be shared with Game Center as part of Apple's platform. This is governed by Apple's Privacy Policy, not ours. We do not see, store, or access your Game Center identity or friends list.
Crash reports
Dose Doubler relies on Apple's built-in crash reporting (TestFlight and the App Store). You can opt out at any time in iOS Settings → Privacy & Security → Analytics & Improvements. We do not run third-party crash reporting (Firebase Crashlytics, Sentry, etc.) in this version.
Children
Dose Doubler is rated 9+ on the App Store and is not directed at children under 13. The app does not knowingly collect personal information from anyone.
Changes
If we add monetization (ads or in-app purchases) in a future update, we will update this policy and disclose the new data handling clearly before that update ships. The version of this policy that applies is whichever was effective on the date of the app version you have installed.
