Mad Eccentrics Become a tester

The app never connects to the Internet. Nothing you type ever leaves your phone.

What the app keeps on the phone

Everything is erased when you uninstall the app or clear its data in Android's settings.

What the app doesn't do

No account, no ads, no analytics, no microphone or camera.

The closed test

To become a tester, you join a Google group and then the test on Google Play. Google handles your email address under its own terms; we only see the list of the group's members, and use it only to open the test. Feedback you leave on Google Play reaches us with the information Google attaches to it.
