What we collect

The calculators run entirely in your browser. Dates you enter are never sent to a server, stored on our side, or logged. For convenience, your calculator settings and checked-off items are saved in your browser's local storage — on your device only, never transmitted to us or anyone else; clearing your browser data removes them. Calendar files are generated on your device.

Analytics

We use privacy-focused, cookieless analytics (Cloudflare Web Analytics) to count page views. It does not track you across sites, fingerprint your device, or store personal information.

Advertising

Pages may display ads served by third-party networks such as Google AdSense. Ad networks may use cookies to personalize ads; you can opt out of personalized advertising atGoogle Ads Settings. We do not share anything you type into a calculator with anyone — including ad networks.
