MasterMindy is an open-source (MIT) Android game by Matteljay. The APK we host is 1.3 MB, it needs Android 5.0 or newer, and it declares no permissions at all.
The file on this page is MasterMindy 20190923, 1.31 MB, and it installs on Android 5.0 and newer.
We compared the signing certificate of this build with the certificate recorded the first time eth.matteljay.mastermindy entered the site, and published both the file's SHA-256 and the certificate's fingerprint above so you can check the download yourself. That comparison says the file was not repackaged by someone else; it is not a review of what the game does.
The manifest declares no permissions at all.
Its licence is MIT. We took this build from F-Droid, and the source for this exact version is linked below.
The most recent release upstream is from Dec 10, 2019, over 6 years ago. It still installs; it is simply not being updated.
We do not show a star rating or an install count for this page: we have no measured figure for either, and a number we cannot source is worth less than an empty field.
