Privacy
Nothing.
No accounts, no analytics, no advertising, no tracking, and no third-party kits that gather data. Nothing you do in the game is sent to us, because there is no server to send it to.
The game saves your best depths, your best depth per mode, and which swimmer, water and soundtrack you chose. All of it is stored on the device by iOS and never leaves it. Deleting the app deletes it.
If you are signed in to Game Center, your best depth for a mode is submitted to that mode's Apple leaderboard when you set a personal best. That is handled entirely by Apple, under Apple's privacy policy. We never see your Apple Account, your name or your friends. If you are not signed in, nothing is submitted and the game plays exactly the same.
The one-time unlock is sold by Apple through the App Store. Apple tells the app whether the purchase exists; that is the whole of it. We never receive or store your payment details, and we cannot see who bought the game.
The game requests no permissions — no location, camera, contacts, photos or notifications. The app does declare a microphone purpose string, because the audio library it uses includes recording code that Apple's tooling detects. Glub Glub never records audio, never asks for microphone access, and iOS will therefore never show you that prompt.
The game is suitable for all ages and collects no personal information from anyone, including children.
If this policy ever changes, the updated version is posted here with a new date below.
