Does weather.com fingerprint you?

Fingerprinting indicators observed.

The latest measured scans include canvas drawing and readback by the same script. This is a fingerprinting indicator, not proof of tracking intent or transmission.

Open evidence JSON ↗

All 7 source records are included in the JSON. 2 older runs have no recorded timestamp; missing provenance stays unknown. The tabs show the latest usable homepage measurement for each setup. Later failed attempts remain in the history. Scan scope and methodology ↗
