Privacy

The calculators run entirely in your browser. Whatever you type into a calculator — dates, times, durations — is used only to compute the result on your own device and is never sent to us or stored anywhere. No account is required.

Analytics and advertising are intentionally disabled. This site sets no cookies, uses no local or session storage, and makes no requests to third-party analytics or advertising services. This page will be updated before either is ever enabled, to describe the actual services, cookies, data flows and choices involved.

This site is hosted on Vercel. Reaching this site at all necessarily means your device sends a request to Vercel's servers, and web hosting inherently involves processing basic technical data about that request — your IP address, the page requested, the time of the request, and similar request and infrastructure log data — the same way any web server works. This happens purely to operate the site, keep it secure and reliable, and diagnose technical problems; it is not used to build a profile of you or track you across other sites. Because Vercel operates a global hosting network, this technical data may be processed on servers outside your own country, including in the United States. We do not separately collect, store or have direct access to these hosting-level logs beyond what Vercel provides as part of its hosting service.
