This policy explains what information the Tough Brain iOS app ("the app") handles. The app is published by Mohammad Sami ("we").
The short version
- You do not create an account. We never ask for your name, email, phone number, contacts, photos or location.
- Your scores and settings are saved only on your device.
- The app shows ads and measures how it is used through Google services. Those services receive some technical information from your device, described below.
Information saved on your device
Your best scores, how many times you played each game, and your music and vibration settings are stored locally on your device. They are not sent to us. Deleting the app deletes them.
Information handled by third-party services
Google AdMob (advertising). The app shows banner, full-screen and optional rewarded video ads using the Google Mobile Ads SDK. To deliver and measure ads, Google may collect information such as your IP address (which indicates your approximate location), device and operating-system details, ad interactions, diagnostic data, and device identifiers. The app does not ask for permission to track you across other companies' apps and websites, so Apple's advertising identifier (IDFA) is not made available to the app.
Google Analytics for Firebase (usage statistics). The app records anonymous events, for example which game was started or finished, together with general device information and an app-instance identifier. We use this only to understand which challenges people enjoy and to fix problems.
Google processes this information under its own policy: policies.google.com/privacy. You can read how Google uses information from apps that use its services at policies.google.com/technologies/partner-sites.
What we do not do
- We do not sell your personal information.
- We do not collect sensitive information.
- We do not combine app data with information that identifies you personally.
Your choices
- On your iPhone, open Settings > Privacy & Security > Apple Advertising to limit personalised ads from Apple, and Settings > Privacy & Security > Tracking to control tracking requests.
- You can reset the app's analytics identifier and remove all locally saved data by deleting the app.
- To ask a question or request deletion of any data connected to you, contact us at the address below.
Children
Tough Brain is a general-audience app. We do not knowingly collect personal information from children. If you believe a child has provided personal information to us, contact us and we will delete it.
