Privacy Policy

This site does not send the data you enter into its calculators to a server; all calculations happen in your browser.

We may use third-party advertising services such as Google AdSense. Google and its partners may use cookies to show ads relevant to you. You can opt out of personalized ads in Google Ads Settings.

We may use analytics tools such as Google Analytics, which collect anonymous usage data. We also keep our own page-view counters (page, language, date) without cookies and without identifying anyone.

If you subscribe to the newsletter we store your e-mail address only to send the weekly newsletter. Subscription starts with the confirmation link in the e-mail and can be cancelled instantly with the link in every issue; on cancellation your address is deleted. If you create an account, your e-mail and the results you save are kept in your account, and your password is stored only as a hash. You can contact us about your data rights under GDPR.

You can manage cookie preferences in your browser settings.
