Privacy Policy

What happens to your data on CalcOtter — the short version: we don't collect it.

Your inputs stay in your browser

Everything you type — amounts, rates, weights, dates — is processed by code running on your own device. Nothing is transmitted to us or stored on a server. Closing the tab discards it.

No accounts, no tracking by us

There is no sign-up and no login. We do not run our own tracking pixels and we do not sell data, because we do not have any to sell. We use privacy-focused, cookieless page-view counting to see which calculators are used most.

Advertising

CalcOtter is supported by ads. When advertising is enabled, Google AdSense and its certified partners may set or read cookies as part of serving and measuring ads; where required, you will be asked for consent, and you can opt out of personalised advertising through Google's ad settings. Ads appear only in the single labelled slot on each page.
