Prices, usage figures, salaries and every other value you enter are processed entirely in your browser. They are not transmitted to a server and are not stored by us.

If convenience features such as recently used tools are added, that information stays in your browser local storage only.

There is no sign-up on this site, and we do not directly collect names, phone numbers or addresses.

If you email us, we keep the message only as long as needed to answer it.

Standard usage information — access logs, browser type, pages visited — may be collected while you browse. It is used to improve the service and diagnose errors.

Third-party advertising, including Google AdSense, may appear on this site. Third-party vendors, including Google, use cookies to serve ads based on a user prior visits to this or other websites.

You can opt out of personalised advertising at https://adssettings.google.com, and you can block or delete cookies in your browser settings.

We do not sell personal information, and we do not share it except where required by law.

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

You can refuse cookies in your browser settings, although some features may then behave differently.
