Rotation counts returning devices with one random id, minted in your browser the first time you visit and stored there. This is yours, shown in full. It is not derived from anything — not your IP address, not your browser, not your hardware — and it means nothing except “this browser again.”

Clear this site’s data and it is gone; if you come back, you are a new device to us, which is the honest reading. What we do and do not record against it is written out in the privacy page.
