Does microsoft.com fingerprint you?

Browser signals observed; fingerprinting is unconfirmed.

Browser API activity met a monitored signal threshold in the latest measured scans. The activity alone does not establish a tracking purpose.

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 ↗
