There's not a lot to say. This is a simple little game and it specifically avoids gathering any info about you in the first place. It doesn't ask for your real name, nor your email address or any other personal information. It requires no online account. It should be completely safe.

However, Google requires a privacy policy for any game requesting certain permissions. In fact, this game makes no such permission requests. But the game was built to be compatible with extremely old versions of android, and apparently android automatically made those permission requests for all apps, back then.

This game uses the normal 'preferences' system to store your high scores.

Enjoy your day on this planet
