Privacy

Short version: what you type stays in your browser, and we do not use cookies.

Your figures

Every calculation runs inside your web browser. Your salary, pension and family details are never sent to our servers and are not stored anywhere by us. If you use the "copy a link" button the figures are encoded in that link, so share it only with people you want to see them.

Cookies and analytics

The site sets no cookies and uses no tracking pixels. We use Cloudflare Web Analytics, a privacy-first service that counts page views in aggregate without cookies, fingerprinting or identifying individual visitors.

Hosting

The site is served by Cloudflare. Like any web host, Cloudflare processes standard connection data (such as your IP address and browser type) to deliver pages and protect against abuse, under Cloudflare's own privacy policy. We do not receive or keep that data.

Contact

If you email us we keep your message for as long as needed to reply. We never add addresses to a mailing list.

Changes

If we add any other service that needs consent, this page will be updated first and you will be asked before anything is set. Last updated 28 August 2026.
