Does wordpress.com fingerprint you?

Browser signals observed; fingerprinting is unconfirmed.

Browser API activity met a monitored signal threshold in the latest measured scans. Some activity was recorded on a challenge page. The activity alone does not establish a tracking purpose.

Open evidence JSON ↗

All 5 source records are included in the JSON. Scan timestamps and versions are shown as recorded. The tabs show the latest usable homepage measurement for each setup. Later failed attempts remain in the history. Scan scope and methodology ↗
