Grand Dice

Grand Dice is a turn-based dice game for 1–2 players. It offers 3 game variants: Criss Cross, Rainbow, and Mega. Players have up to 3 rolls per turn (Mega: 4). The goal is to achieve a high score by scoring points in available sheet fields.

The Hall of Fame keeps track of high scores and won games so players can best each other in the long run. Hall of Fame data is stored on iCloud so your progress is not lost when you have a new device.

The current game is automatically saved locally so it can be resumed later.

Grand Dice supports Game Center for the first player. There are leaderboards for all game variants.

Privacy

Access Rights

The app does not request access to hardware features of the device, for example Bluetooth or the camera. It also does not request access to the local network or the contacts on the device.

Information Collected

The app and the app developer do not collect personal information.

The app does not display ads and does not perform user tracking. It does not establish direct network connections to internet servers hosted by the developer or third parties.

The app uses iCloud by Apple Inc. to store non-sensitive information: Hall of fame data (scores, player names, dates), and player information (name, favourite color). Player names are usually nicknames and do not reveal personal identities.

The app provides a function to visit the app support website. The website is opened externally (outside the app) in the default browser.

The app uses Game Center which is operated by Apple Inc. and accessed solely with the standard iPadOS API.

Log Files

At operating system level (iPadOS), the user is able to permit sharing developer information (such as crash logs) with the developer. This information is used by the developer solely to troubleshoot programming errors and abnormal app behavior. It is deleted immediately when the issue has been resolved, deemed unresolvable, or dismissed. The collection and transmission of such information is performed by the operating system and its owner, Apple Inc. The app does not collect or send any logs.

If the user does not wish to share developer information, it is up to him/her to opt out of this feature in the operating system settings.
