Sydneydoku has no accounts and collects no personal information.
- Your puzzle progress and result are stored only in your own browser (localStorage). We never receive them as identifiable data.
- We record anonymous, aggregate gameplay statistics — for example, how many people played a given day's grid and the overall distribution of scores — to improve the game. These contain no personal identifiers.
- We do not sell data or use third-party advertising trackers.
