Does office.com fingerprint you?

No monitored fingerprinting signals observed in the latest measured scans.

No monitored signal family met its threshold in the latest measured scans. This limited visit does not establish that the site never fingerprints visitors. Earlier runs remain available below.

Open evidence JSON ↗

All 14 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 ↗
