Local notes
The run notebook and class comparison can store choices in this browser’s local storage. They are not uploaded to an account or cloud-save service by this site. Clearing your browser data can remove them.
Share links and exported files
A notebook share link contains a copy of your notes in the part of the address after the # symbol. Anyone you give that link to can read those notes. Avoid including personal information. Exported note files are downloaded to your device.
Optional visit statistics
If you allow analytics, Google Analytics uses cookies to measure page visits, traffic sources, approximate country, browser information, language switches and clicks to the original game. Your notebook text, search text and the query or share fragment of your address are not sent by our analytics code. Advertising personalization is disabled.
You can decline and use every guide and tool. Choose Analytics settings in the footer to change your choice. Your choice is stored on this device for up to 180 days. When you withdraw permission, this site stops loading analytics and clears its Google Analytics cookies.
Google processes analytics data under its own privacy practices. Fonts and artwork are served with this site. The hosting provider may process ordinary access logs to operate the website.
External websites
The original game and source links open other websites, which have their own privacy practices. The device check requests browser graphics capabilities locally; it does not fetch game files or report the result to us.
