This page tells you how personal information is collected, used, shared and stored in the app "Bubble Wrap" by Donutask.
The app uses the Unity game engine. Unfortunately, they inject this silly tracking stuff:
unique device identifiers (e.g., IDFV for iOS devices and Android ID for Android devices); IP address; country of install (mapped from IP address); device manufacturer and model platform type (iOS, Android, Mac, Windows, etc.) and the operating system and version running on your system or device; language; CPU information such as model, the number of CPUs present, frequency, and instruction set support flags; the graphics card type and vendor name; graphics card driver name and version (e.g., “nv4disp.dll 184.108.40.206”); which graphics API is in use (e.g., “OpenGL 2.1” or “Direct3D 9.0c”); amount of system and video RAM present; current screen resolution; version of the Unity Editor used to create the game; sensor flags (e.g., device support for gyroscope, touch pressure or accelerometer); application or bundle identification (“app ID”) of the game installed; unique advertising identifiers provided for iOS and Android devices (e.g., IDFA or Android Ad ID); and a checksum of all the data that gets sent to verify that it transmitted correctly.Source: https://unity3d.com/legal/privacy-policy
It is pointless to track people popping virtual bubbles, so I don't add further trackers.
The Bubble Wrap settings are stored only on your device, they contain no personal information.
The app contains no advertisements. This means no advertisers can track you in the app. This is also to increase realism as physical Bubble Wrap has no ads.
