Cookies and local storage. We use your browser's local storage to remember preferences such as theme and units. We do not use these to identify you.
Advertising. We may display ads through third-party vendors, including Google AdSense. These vendors may use cookies to serve ads based on your visits to this and other sites. You can manage ad personalization in your Google account settings and via Google's Ads Settings.
Analytics. We use Google Analytics (GA4) and Vercel Web Analytics to understand aggregate traffic. Google Analytics sets a cookie to measure visits; it does not collect personally identifying information, and advertising signals stay off. You can opt out via your browser settings or Google's opt-out add-on.
