Privacy

Your calculator inputs

Every calculation on PlainSumsruns locally in your browser. The amounts, rates and figures you enter are not transmitted to us, not stored, and not associated with you in any way. Close the tab and they're gone.

Analytics

We use privacy-friendly, aggregate analytics to understand which calculators are useful — for example, page views and general location at the country level. This data is anonymous and is never tied to the values you enter.

Advertising

If this site displays ads in future, ad partners may use cookies to serve relevant ads. Where required, you'll be asked for consent and can opt out. We will keep ads non-intrusive and clearly labelled.

Your choices

You can block cookies in your browser settings without losing any calculator functionality, because the tools don't depend on them. Questions about privacy? Reach us via the contact page.
