What this site does
Boring Tools provides free calculators that run in your browser. We do not require an account, and calculator inputs are not sent to our servers for storage.
Cookies
We use cookies and similar technologies. Essential cookies (or local browser storage) may be used so basic site features work — for example remembering recent calculations on your device. Third-party cookies may be set by advertising partners such as Google AdSense to serve, personalize, and measure ads. You can control cookies through your browser settings; blocking some cookies may affect ads or site features.
Google AdSense & advertising
We may show ads through Google AdSense. Google, as a third-party vendor, uses cookies to serve ads on this site. Google’s use of advertising cookies enables it and its partners to serve ads based on your visits to this and other sites. You can learn more and opt out of personalized advertising via Google Ads Settings.
Data stored on your device
Calculator history and similar preferences may be saved in your browser’s local storage on this device only. Clearing site data in your browser removes them. We do not sync that history to our servers.
Affiliate links
Some product links may be affiliate links. If you buy through them, we may earn a commission at no extra cost to you. This helps keep the calculators free.
Analytics & logs
Hosting providers may collect standard server logs (IP address, browser type, pages requested). If we add analytics later, this page will be updated with details and opt-out options.
