Privacy

The short version: your games stay on your device.

What Sudoku Mill stores

Your current game, your settings and your statistics are saved in your browser's own storage on this device. They are never sent to us or to anyone else. Clearing this site's data in your browser deletes them.

After your first visit, the browser also keeps a copy of the app itself, so that it works offline.

What it doesn't do

• There are no accounts and no sign-in.
• There is no tracking, no analytics and no advertising.
• Puzzles are created on your device, not on a server.

Sharing and importing

A share link contains only the puzzle and its level, never your progress. It goes wherever you choose to send it. A puzzle you import is read on your device.

Beta feedback

Send feedback opens a form run by Tally, an online form service. Besides your answers, the app adds a few details to help us understand them: the app version, the kind of device (phone, tablet or computer), whether the app is installed, your theme, your input method and the level of the game in progress. The form doesn't ask for your name or email, so please don't include personal details in your answers.

Hosting

The site and the app are delivered by Amazon Web Services. As with any website, delivering the pages involves technical data such as your IP address and browser type. We don't use it to identify, track or profile you.
