Privacy policy

1. What you type into the tools

Values entered into calculators and converters are processed inside your browser only. They are not sent to a server and not stored by us. Some tools mirror the inputs into the address bar so that a result can be shared; that address goes nowhere unless you copy and share it yourself.

2. Information collected automatically

The site is hosted on Cloudflare, which may temporarily process connection data such as IP address, browser type and request time to protect and operate the service.

We use Google Analytics to understand which pages are visited, on which kinds of devices and from which approximate regions. IP addresses are anonymised. Google describes its processing in the Google Privacy Policy.

3. Advertising and cookies

We do not currently show ads or set advertising cookies. This section will be updated if that changes.

4. Affiliate links

Some pages may contain affiliate links, always inside a clearly labelled box. If you buy through such a link we may earn a commission at no extra cost to you.

5. Browser storage

Convenience settings such as display preferences may be kept in your browser's local storage. That information stays on your device.

6. Children

The site is not directed at children under 13 and we do not knowingly collect personal information from them.

7. Contact

Questions about privacy can be sent through the contact page.
