Privacy Policy

What we collect

Nothing personal. Our calculators run entirely in your browser. The numbers you type are never sent to us, stored on a server, or associated with you. We do not operate user accounts and do not ask for your name, email, or payment details.

Analytics

We use Google Analytics and Microsoft Clarity to understand aggregate usage (which pages are popular, approximate location by country, device type). These tools set anonymous cookies and process data under their own privacy policies. This anonymous, aggregate analytics is the only data we collect — your calculator inputs are never part of it. You can block these tools with a browser setting or extension; the calculators still work.

Advertising & affiliate cookies

We display ads through Google AdSense. AdSense and its partners may use cookies to serve ads based on your prior visits to this or other sites. You can opt out of personalized advertising in two ways: Google Ads Settings and YourAdChoices (aboutads.info). Some pages contain affiliate links; clicking them may place a cookie set by the partner to track a referral — this never affects your price.

Third-party advertising vendors that may serve ads on this site include Google AdSense (Google LLC). These vendors may use cookies and similar technologies under their own privacy policies.

Your rights

Because we hold no personal data about you, there is nothing for us to delete or export. For questions, contact [email protected].
