What are cookies?
Cookies are small text files stored by your browser when you visit a website. They help sites remember your settings and understand how the site is used. We also use "local storage", a related browser technology, to keep your preferences on your device.
Types of cookies we use
Essential: Needed for the site to function and stay secure, such as protecting against abuse.
Preferences: Remember choices like light or dark theme and any calculators you save. These are stored in your browser's local storage, not on our servers.
Analytics: Help us measure aggregate usage and performance so we can improve the calculators. This data is privacy-respecting and not used to identify you personally.
How we use cookies

Managing cookies
You can control or delete cookies and local storage through your browser settings. Most browsers let you block cookies, clear stored data, or browse privately. Disabling cookies will not stop the calculators from working, but it may reset your preferences each visit.
