Short version: what you type into the calculators stays on your device. Ads, if they're showing, come from Google, and Google uses cookies to choose them.
Calculator inputs
Every calculation runs in your browser. The prices, costs and settings you enter are not sent to us, not stored and not shared.
Analytics
We may use privacy-friendly, cookie-free analytics (Cloudflare Web Analytics) to count page views. It doesn't track you across sites or build a profile of you.
Advertising and cookies
To keep the calculators free, the site may show ads served by Google AdSense. When it does:
- Third-party vendors, including Google, use cookies to serve ads based on your earlier visits to this site or to other websites.
- Google's use of advertising cookies lets it and its partners show you ads based on your visits to this site and other sites on the internet.
- You can turn off personalised advertising in Google's Ads Settings. You can also opt out of some other vendors' use of cookies for personalised ads at aboutads.info.
If you're in the UK, the European Economic Area or Switzerland, you'll be asked for consent before any advertising cookies are set, and you can change your choice later from the privacy link in that message. Google explains what it does with this information in How Google uses information from sites or apps that use its services.
Affiliate links
Some pages may link to tools for sellers. If we earn a commission from a link, the page says so, and the partner site may be told that you came from here. Links never change the fee numbers.
