What a cookie is
A cookie is a small file a website stores in your browser to remember information between visits. Similar technologies are used alongside them, such as the browser’s local storage (localStorage).
Cookies we use

|---|---|---|
| Technical | Remembering your light or dark theme and the last values you used in a calculator. Stored in localStorage and never leaves your device. | No |
| Statistics (Vercel Web Analytics) | Counting visits in aggregate. It uses no cookies, stores nothing in your browser and doesn’t identify you across visits. | No |
| Advertising (Google AdSense) | Showing ads, limiting how often you see the same one and measuring their performance. They may be used to personalize advertising if you accept. | Yes |
How to manage your consent
The first time you visit, a notice lets you accept, reject or configure non-essential cookies. Until you accept, advertising cookies aren’t installed. You can change your choice at any time from the cookie settings link in that notice.
You can also block or delete cookies in your browser settings. Keep in mind that blocking technical storage may stop the site from remembering your preferences.
