Privacy Policy

Your calculator inputs are processed on your device.

Information entered into tools

Dates, durations, excluded working dates and time-zone selections are calculated in your browser. This application does not send them to a database or third-party calculation API. Optional shared countdown links include the settings you choose in the URL fragment; share them only with people you intend.

Local preferences

We use browser local storage to remember your light/dark theme and 12/24-hour clock preference. You can clear these preferences in your browser’s site-data settings. Blocking local storage does not prevent the calculators from working.

Hosting

The site is hosted on Cloudflare. Like other hosting providers, Cloudflare processes connection information such as IP addresses and request metadata to deliver and protect the website. See Cloudflare’s privacy policy.

Analytics and advertising

This version does not install advertising scripts, third-party analytics, marketing pixels or tracking cookies. If those features are added, this policy must be updated to reflect the actual configuration.

Feedback

GitHub handles information you choose to submit in a public issue under its own policies. Avoid posting private information. Use the contact page for the available feedback channel.
