Dead Letter Night
The short version: the game collects nothing, sends nothing, and has no way to do either.
Nothing. Dead Letter Night does not collect, store, transmit or share any personal data or usage data of any kind.
The application contains no network code. It cannot send data anywhere, because it has no means of doing so. It requests no Android permissions.
Save files, screenshots taken by the save system, and your settings — text speed, volumes, text size and similar. These stay in the application’s private storage on your device and are never transmitted.
You can erase all of it at any time from Settings → Erase All Progress, or by uninstalling the app.
The game is not directed at children, but since it collects no data at all, it collects no data from children either.
If a future version ever adds anything that touches the network — a store unlock, for example — this policy will be updated before that version is published, and the change will be described here.
Questions about this policy can go to the support address listed on the Google Play listing for Dead Letter Night.
