What Trackers Can See (local)

👁️
Educational: This report stays on your device. We do not send fingerprint data anywhere. Real click/email trackers need a server to receive beacons — viewing this page does not notify marketers about your IP beyond normal web hosting logs for the HTML file itself.

Privacy: This tool runs 100% in your browser. We do not log clicks, opens, IPs, or campaign data on ITCOH servers.

FAQ

Do you upload my fingerprint?

No. The report is built with JavaScript in your tab and never posted to ITCOH.

Why show cookie/localStorage as booleans only?

To avoid exfiltrating contents. We only show whether cookies exist / storage works.

Is this a full anti-fingerprint tool?

No — it’s educational. Blocking trackers needs browser settings or extensions.

Why can’t ITCOH offer email open tracking?

Open pixels and click redirects must hit a server to log IP/time. We deliberately don’t run that.
