What we collect

The calculators on this site run entirely in your browser. Nothing you type into a calculator is sent to us or stored by us.

Hosting logs

The site is served by Cloudflare, which keeps standard, short-lived server logs (IP address, browser type, pages requested) for security and performance. We do not use these to identify individual visitors.

Advertising and cookies

This site may display ads served by Google AdSense. Google and its partners may use cookies, including the DoubleClick cookie, to show ads based on your visits to this and other websites. You can opt out of personalized advertising at Google's Ads Settings or at aboutads.info. Third-party vendors may also use cookies to serve ads; their use is governed by their own privacy policies.

Analytics

We may use privacy-respecting, cookie-free analytics to count page views. If that changes to a cookie-based tool, this page will be updated.

Children

This site is not directed at children under 13 and does not knowingly collect information from them.
