# Purchases

To enable the automated purchase feature, set the ``GOOGLE_PLAY_PUBLIC_KEY`` environment variable.
The value for the official builds which are distributed using the Play Store can
be found at <https://codeberg.org/timelimit/timelimit-android/src/commit/3da677877f4dde0b1b01523daae33745f14e08ac/app/build.gradle#L49>.

Additionally, there is the admin API which allows one to unlock the
premium features.
