Fairsum

Privacy

Fairsum is built privacy-first. In short: your numbers stay in your browser, we don't ask who you are, and our analytics are anonymous and cookieless.

Your calculator inputs never leave your browser

Every calculation — salary, loan amount, rate, deposit and the results — runs entirely in your browser. Those figures are never sent to us or anyone else, and are never stored.

No accounts, no sign-up, no email

Fairsum doesn't ask you to register or hand over any personal details to use the calculators. There's nothing to log in to.

Cookieless, privacy-first analytics

We use privacy-friendly, cookieless analytics (Umami) to understand aggregate usage — which calculators are used and how often. It sets no cookies, doesn't track you across sites, and collects no personal information. We record that a calculation happened and which calculator — never the numbers you entered.

No advertising trackers

There are no third-party advertising or social-media tracking pixels on the site.

Any future links out to partners

If Fairsum ever links to a lender or partner, clicking that link takes you to their site, which has its own privacy policy. We may count that a link was clicked (the destination site, not who you are) so we can see which tools are useful.

This page describes current practice and may be updated if the site's features change. Questions: contact the site owner.
