This Privacy Policy explains how Postmark Protocol handles information. Postmark Protocol is a single player puzzle game for iPhone and iPad.
No Data Collected
Postmark Protocol does not collect, store, or transmit any personal information. The game works fully offline and never requires you to create an account, sign in, or connect to the internet. Nothing you do in the game is sent to us or to anyone else.
Local Save File
Your delivery progress, unlocked levels, best results, and your music, sound, and haptic feedback preferences are saved only in a file on your own device. This information stays on your device and never leaves it. We never see it, and it is never uploaded anywhere.
No Advertising, Analytics, or Tracking
This app contains no advertising, no analytics services, no tracking technologies, and no in app purchases. It does not use any third party software development kit that collects data. Because nothing is collected, nothing is ever shared with a third party.
Children's Privacy
Postmark Protocol does not knowingly collect personal information from anyone, including children. Since no personal information is collected from any player, no additional steps are required to protect a child's privacy while playing this game.
Your Choices
Because all game data stays on your device, you are always in control of it. You can clear your saved progress at any time using the Reset Progress option inside the game's Settings menu. Uninstalling the app removes all locally stored data.
Changes to This Policy
This policy may be updated occasionally to reflect changes to the app. The date at the top of this page shows when it was last revised. Continued use of the app after a change means you accept the updated policy.
