Grudge Rush is built so that your game data never leaves your device.
Everything the game creates, from the rival ladder and your grudge list to your run history, unlocked cosmetics, and settings, is stored only on your device in the app's local storage. There are no Grudge Rush servers, and nothing is uploaded. All forty rivals are simulated on your own device; none of them is another person.
If you sign in to Apple's Game Center, Grudge Rush can submit your scores to its leaderboards and report which of its achievements you have earned. That data goes to Apple under your own Apple Account and is covered by Apple's Privacy Policy. Grudge Rush never stores or sends a Game Center identifier itself. If you are signed out, those features simply hide and the game plays the same.
If you choose to save a replay clip, the recording is made on your device by Apple's ReplayKit and goes only where you send it. Grudge Rush never sees or uploads your clips.
Grudge Rush offers optional cosmetic in-app purchases, including the Crown Club weekly subscription. They change how the game looks and never how it plays. All purchases are processed entirely by Apple through your Apple Account. Purchase management and payment information are handled by the App Store; Grudge Rush never sees your payment details. Purchase entitlements are checked on-device via Apple's StoreKit. See Apple's Privacy Policy for how Apple handles purchase data.
If you allow notifications, Grudge Rush schedules a small number of local reminders on your device, at most one per day and four per week, and one switch in Settings turns them all off. They are created and delivered entirely on your device. Nothing about them is sent to us.
Grudge Rush does not collect data from anyone, including children.
If this policy changes, the updated version will be posted at this page with a new effective date.
