Sudoku Swap collects no personal information. There are no accounts, no sign-in, and no ads. We record anonymous, aggregate gameplay analytics to understand how the game is used — nothing that identifies you.
Anonymous gameplay events (for example: a game started, a swap made, a puzzle solved with its difficulty and move count) and basic device context (device type, OS/browser, screen size, language). Each visitor is assigned a random anonymous ID so we can count sessions. This ID is not linked to your name, email, contacts, or any account.
We do not collect your name, email, phone number, contacts, photos, precise location, or any data that identifies you personally. We never sell or share data with advertisers.
Events are sent to Studio Typo's analytics service, which forwards aggregate data to Mixpanel. The service may derive coarse location (such as country) from your IP address at the network edge; we do not store your IP ourselves. See Mixpanel's privacy practices for how they process aggregate analytics.
A small amount of data is stored locally in your browser only: your random anonymous ID and whether you've seen the intro. Clearing your browser storage removes it.
Sudoku Swap is suitable for all ages and does not knowingly collect any personal information from children.
