The XtremeOR app
XtremeOR does not collect, transmit, sell or share personal data through the app. There are no accounts, advertisements, analytics, tracking or third-party data-collection SDKs.
Scores, campaign progress and preferences are stored locally on your device. Music and sound effects are generated on-device; microphone input is not recorded.
Local data, deletion and device backups
On iPhone and iPad, deleting the iOS app removes its local data. Offloading the app does not remove that data. Device backups may retain copies.
Deleting the Mac app may leave preferences behind. Contact support@totalhardwaredomination.uk for help removing them.
Device backups are governed by your device settings. Local scores and progression do not synchronize between devices.
