What stays on your device
We save your progress, solved puzzles, Atlas, streak and settings in your browser's local storage. That data never leaves your device, and we can't see it. You can delete it at any time by clearing your browser's data for this site.
What we don't collect
We don't ask for your name or email address. We don't run advertising, tracking cookies or third-party analytics scripts.
Hosting
The site is hosted on Cloudflare. Like any web host, Cloudflare processes technical request data, such as IP addresses, to deliver pages and protect the site from abuse. We use it to serve the site, and we don't use it to identify visitors. See Cloudflare's privacy policy.
Changes
If this changes, for example if we add analytics, we will update this page first.
