What cookies are
Cookies and similar storage let a site remember information in a browser. Some are necessary for requested features; others may support measurement or advertising.
Our use
Calculator inputs need no account and are processed locally. One stored value remembers your consent choice.
Analytics cookies
Yandex Metrica sets cookies to tell repeat visits apart and to reconstruct how a page was used (session replay). They carry no calculator input. Refuse them with the Metrica opt-out extension or by blocking cookies for this site.
Advertising cookies
Advertising here is served by Google and its partners, which may set cookies to measure performance, cap repetition and, where permitted, select ads from previous browsing. Google’s own use is described at policies.google.com/technologies/partner-sites. Opt out in Google Ads Settings, aboutads.info or youronlinechoices.com. These cookies never carry your calculator inputs.
Third parties
Hosting and security providers may process request data to deliver and defend the site. Advertising or analytics partners, if enabled, have their own privacy and cookie policies.
Controls
Use the cookie notice when shown, or your browser settings, to allow, block, or delete storage. Blocking optional storage does not prevent the calculators from performing their core calculations.
