These apps collect, store and share no personal data whatsoever.
None of the four declares the INTERNET permission. They are
technically incapable of sending data anywhere.
No analytics, no crash reporting service, no advertising identifier, no location, contacts, camera or microphone. None of it is used.
Only your own preferences and scores, in the watch's private app storage: best score, chosen theme, sound preference, the layer of an unfinished run, the world you last played, and which tutorial hints you have already seen. Uninstalling the app deletes them.
If an app closes unexpectedly, the error trace is written to a file inside the app's own private storage on the device. That file is never transmitted anywhere. It stays on the watch and is deleted with the app.
VIBRATE — vibration is the games' primary feedback channel.
WAKE_LOCK — keeps the screen awake while you play. Nothing else
is requested.
Because the apps collect no data at all, they collect no data from children either.
