Privacy

This describes how the site is built. It is not a legal agreement.

What the calculators do with your inputs

Calculations run in your browser using JavaScript. The site's code does not send the numbers you enter to a server, and there is no account system or database.

Shareable links

As you change inputs, the page updates its address with them (for example ?v=8&a=128) so you can copy and share a link. Anyone you give the link to can see those values, and they may appear in your browser history. When someone opens such a link, the values are part of the page address sent to the hosting provider, so they can appear in its request logs. Do not put anything sensitive in the inputs.

Cookies and tracking

The site's own code does not set cookies, run analytics, or load advertising, third-party scripts or third-party fonts. The hosting provider operates separately from this code and may have its own practices. If the site's behavior changes, this page will be updated.

Hosting

Pages are delivered as static files from a hosting provider. Like any web host, the provider may keep standard request logs (such as IP address, requested page and browser type) for operation and security, and its own policies apply to that data. This site does not control those logs.
