Privacy
There is no account and no server. Nothing you do here is sent anywhere.
What is stored
Lesson progress, timer sessions, scramble history, the daily result and your settings live in your browser's local storage. They never leave your device.
Camera
The solver can read your cube through the camera. Frames are processed in the page to find sticker colours and are never recorded, stored or transmitted.
Third parties
No trackers, no advertising, no third-party scripts. The only network requests are for this site's own files.
Clearing your data
Clearing site data in your browser removes everything. Timer sessions can also be exported to JSON or CSV first.
