Privacy
Your puzzle stays yours.
Updated 2 August 2026
Velune Sudoku is designed to work without Evisoft collecting personal data.
Data collected by Evisoft
None. The app contains no analytics SDK, advertising SDK, cross-app tracking, Evisoft account system, or Evisoft server-side profile.
Data stored on your device
Your current puzzle, entries, notes, elapsed time, mistakes, and hint balance are saved locally so you can continue later. Removing the app removes this local data.
Optional Game Center score sharing
If you are signed in to Apple Game Center, the app asks for your permission before it submits a completion time for the first time. If you choose to share, the completion time and your Game Center player identity are sent to Apple Game Center, where your nickname and time may appear on global leaderboards. Evisoft does not keep a separate server copy.
If you choose Don't Share, or you are not signed in to Game Center, the app does not submit the completion time. Your choice is saved on your device.
Network access
Core gameplay does not need a network connection. A connection is used only when Apple Game Center authentication or an approved score submission requires it.
Children
Evisoft does not knowingly collect personal information from children through the app.
