Privacy policy

Last updated: 13 October 2026.

Calculator inputs

Calculations run in your browser. This release does not send calculator inputs to an application API and does not use analytics, advertising, cookies or local storage. Fonts and scripts are served with the website.

URLs and shared calculations

After a calculation, the address bar contains the selected region, dates and counting settings. Copying a share link includes those values. Anyone with the link can read them. The link may also be saved in browser history, synchronized by your browser or recorded by your network provider.

When you open or reload a parameter URL, it is requested from the hosting provider. Therefore, avoid putting confidential dates into a shared link. We use a no-referrer policy to keep the page URL out of referral headers sent to other websites.

Hosting

The website is hosted using Cloudflare. The hosting provider processes request information, such as IP address, requested URL and browser information, to deliver and protect the service. Infrastructure processing is separate from the in-browser calculation. See Cloudflare’s privacy policy for its practices.

Contact email

If you email contact@working-calendar.com, your address and the message you send are forwarded by Cloudflare Email Routing to Gmail so we can respond to your request. Do not send sensitive personal information. Ask through the same address if you want your correspondence deleted, subject to applicable retention requirements.

Future changes

Analytics or advertising will require a separate privacy review and an updated notice before activation. No analytics or advertising consent is requested in this release because neither is loaded.
