Privacy
We set no tracking cookies. Analytics on this site are:
- Google Analytics 4 in cookieless mode (client storage disabled, Google signals and ad personalisation off) — page and event counts only; returning visitors look like new ones by design.
- A first-party beacon that records the page path, the referrer reduced to a hostname, and outbound affiliate clicks reduced to a target hostname — no cookies, no identifiers, no personal data.
We collect no names, no emails, no accounts. Outbound links go to the sites they name; their privacy practices are their own.
Embedded videos: some pages embed YouTube videos in YouTube's privacy-enhanced mode (youtube-nocookie.com). No YouTube cookies are set by loading the page; when you press play, the video streams from YouTube and Google's own privacy practices apply from that point.
Collection tracker
The collection tracker stores the figure names, notes, list status and quantities you enter in this browser’s local storage. We do not upload this collection or its JSON backups and CSV exports. Clearing browser data removes the local copy; export a JSON backup first. Aggregate events record actions such as save, export, import or calculate, without collection content or measurement values. Existing site analytics described above still apply.
