Privacy Policy
Last updated: 28 October 2026
What we collect
Our server keeps standard access logs: IP address, date and time, the page requested and your browser's user agent. We use them to keep the site secure and working, and we delete them after 14 days. There are no accounts, logins or newsletters on this site.
Puzzle progress on your device
When you play a level on our grid, your board is saved in your browser's local storage under keys that start with ck.nono. It never leaves your device. You can remove it at any time with the Clear grid button on a level page or from your browser settings.
Reports and email
If you send a report from a level page, we store the level number and your message so we can check the answer. We do not ask for your name or email address. Your IP address is used only to limit spam and is not stored with the report. If you email hello@crazyfit.one, we use your address only to reply.
Advertising
This site shows ads through Google AdSense. Google and its partners may use cookies or device identifiers to show ads based on your visits to this and other websites. Where the law requires it, for example in the European Economic Area, the United Kingdom and Switzerland, you are asked for consent before any advertising cookie is set, and you can change your choice at any time with the Ad choices link at the bottom of every page. You can turn off personalised ads in your Google ad settings at adssettings.google.com. Google explains how it uses data at policies.google.com/technologies/partner-sites.
Changes
If this policy changes, the date at the top changes with it.
