Your calculations stay on your device
Every calculator on CalculatingThis.com runs entirely in your web browser. The numbers and dates you enter are not sent to our servers, stored or shared.
Information we store
If you switch between light and dark mode, your choice is saved in your browser's local storage so the site remembers it. You can clear it at any time through your browser settings.
Third-party services
Our fonts and other site files are served from our own server. Our web host keeps standard server logs (such as IP address, browser type and pages requested) for security and performance purposes.
Advertising
We use Google AdSense to show ads, which keeps this site free. Google and its partners are third-party vendors that use cookies (and similar technologies) to serve ads based on your prior visits to this website and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info.
- Learn more about how Google uses information from sites that use its services.
Visitors in the European Economic Area, the UK and Switzerland are asked for consent before personalized ads are shown, and can change their choice at any time through the privacy message shown on the site.
Ads never see the numbers you enter into our calculators — those stay in your browser.
