Search a site. See who shares its ad companies.
Look up a familiar site and see other well-known sites that loaded the same advertising or high-risk companies. That is how an article on one site can follow you to another — an opportunity to recognize you, not proof a specific ad was sold.
What website tracking audits show
Each entry is a registrable domain (eTLD+1) with aggregated metrics from the Privacy Companion extension: tracking surface score, third-party contacts, known trackers, cookies, and local storage keys. Operator and shared audits try to accept cookie banners first so counts reflect post-consent tracking; if no banner is found, metrics are as-loaded.
Users explicitly tap Share to publish a counts-only summary — no cookie values, no storage contents, no full URLs. Operators may also contribute automated audits using the same counts-only format.

Editorial starting points — not a live ranking. Open a domain if someone has shared an audit.

Chats and feeds that are hard to leave.
Directory at a glance
Headline counts from opt-in shared audits in the directory — not a census of the whole web.

Run your privacy auditFAQ
Where does the data come from?
From Privacy Companion extension users who opt in to share counts-only audit summaries for a domain, plus operator batch audits that use the same format.
Can a site have a low score and still track me?
Yes. The score reflects third-party exposure observed during shared visits — ideally after accepting cookies when a banner is present — not every tracking technique (browser fingerprinting needs your privacy audit on the homepage).
Why are some domains missing?
Until someone shares an audit for that domain, it will not appear in search or rankings.
Why are these sites linked?
They loaded the same advertising or high-risk third parties during shared audits. Analytics, CDNs, and ubiquitous ad tags such as DoubleClick do not create a link on their own. Observation is an opportunity to recognize a visitor across sites — not proof a particular ad was shared.
These results are contributed by users who explicitly shared an audit (and operator batch runs). They are counts-only summaries for education, not legal proof of tracking. Scores aim to capture post-consent tracking when a cookie banner could be accepted.
