Privacy Policy
Last updated: May 21, 2026
The short version: there's no account to create and nothing to log in to, so we never ask for your name, email, or anything that identifies you personally. The longer version is below, in plain language.
What we don't collect
We don't have user accounts, sign-ups, or profiles. We don't ask for your email to use the solver, and we don't sell or rent data to anyone. The letters you type into the custom solver are processed to find solutions and aren't tied to your identity.
What stays on your device
Small preferences — like your theme choice — are saved in your browser's local storage. They live on your device, never get uploaded to us, and you can clear them anytime through your browser's settings.
Analytics
We use Google Analytics 4 to see things like how many people visit and which pages are popular, all in aggregate. It helps us decide what to fix and build next. This involves cookies and basic data such as your approximate region, device type, and browser. We don't use it to identify individual visitors. You can read how Google handles this data in Google's Privacy Policy.
Advertising
This site is free, and ads are how we keep it that way. We use Google AdSense to display them. Google and its partners may use cookies to show ads based on your prior visits to this and other sites. You can opt out of personalized advertising in Google's Ads Settings, and learn more about how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites. You can manage cookies for any site through your browser settings.
Children
This site is meant for a general audience and isn't directed at children under 13. We don't knowingly collect personal information from them.
Changes & contact
If this policy changes, we'll update the date at the top of the page. Questions about your privacy are welcome at .
