LuckyRoll is a free dice app by Mercury Project. It has no ads, no accounts and no tracking. We do not collect, store or share any of your data.
To work, LuckyRoll keeps a few things in its own private storage on your device. None of it is ever sent to us or to anyone else:
LuckyRoll uses the camera only when you choose Take Photo for a player, and only to take that photo. When you choose Choose from Library, the system photo picker shows your library; LuckyRoll only receives the single photo you pick and has no access to the rest of your library.
To let you shake your iPhone to roll, LuckyRoll reads the motion sensors while it's open. The readings are used on the spot to move the dice and are never stored or sent anywhere.
LuckyRoll offers optional In-App Purchases to support the developer. Payments are handled entirely by Apple through the App Store; we never see your name, payment details or Apple Account. The app only learns from Apple which of its own items are unlocked on your device, and keeps that on the device.
LuckyRoll contains no analytics, advertising or tracking code and uses no third-party services. The only online feature is Apple’s App Store, for the optional purchases.
You can remove a player's photo in the Players screen (tap the photo, then Remove Photo), clear names with the ✕ button, and clear recent rounds in Recent Rounds. Deleting the app removes everything it stored.
LuckyRoll is suitable for everyone and collects no information from anyone, including children.
If this policy ever changes, the updated version will be posted on this page with a new date.
