Privacy
We count page views without cookies; no personal data is stored.
To see which pages people find useful, the server notes each page view: the page, when, how long it took, the site that linked to it (just its name, such as google.com), what you searched for here, and whether a search engine or AI crawler made the request. It does not store your IP address or browser details. To count visitors, it uses a scrambled code made from those details and a random value that changes every day and is then deleted, so a visit can’t be traced back to you or linked to another day. Page views are deleted after 30 days; only daily totals are kept.
Browsing sets no cookies. Signing in sets one cookie, which keeps you signed in. Your account holds your email, display name, password hash and the cards you track; your collection is only shown to others if you choose to share your profile. A bug report or feature request keeps the page it came from, your browser name (to help reproduce bugs) and an email address only if you give one.
