The short version
Everything you type into the calculator is processed in your own browser and is never sent to us. We do not sell personal data and we do not use advertising trackers.
Information stored on your device
To make the site more convenient, your browser's local storage keeps a few settings on your device only:
- your light or dark theme choice,
- your preferred unit and rounding,
- your recent calculation history (you can clear it at any time with the “Clear” button),
- whether you answered the “Did this solve your problem?” question.
This information never leaves your device, and you can remove it by clearing your browser's site data.
Contact form
If you send us a message, the name, email address and message you enter are delivered to us through our form provider, Web3Forms, so that we can reply. We use this information only to answer you and delete it when it is no longer needed.
Server logs
Like most websites, our hosting provider may automatically record technical information such as IP address, browser type and the pages requested, for security and to keep the service running. These logs are kept for a limited time and are not used to identify you.
Cookies
The site does not set advertising or tracking cookies.
Children
The site is suitable for students of all ages and does not knowingly collect personal information from children.
