Star us on Codeberg, open an issue, or send a correction — the catalogue is public so anyone can audit and improve it.
ConsentTheater is a free, open-source lookup for cookies, domains, and trackers. Type a cookie name or domain and you'll see who's behind it, what it does, how invasive it is, and where it sits under GDPR. We also publish a handbook of plain-language privacy guides.
Every website silently talks to dozens of third parties — analytics, ad networks, fingerprinting libraries, session recorders — and almost none of it is explained to the visitor in understandable terms. We catalogue what those trackers actually do, so individuals can read it, and compliance teams, journalists, and researchers have a consistent reference to cite.
Yes, free. No ads, no sponsorships, no paid placements in the catalogue. The site loads no third-party scripts, sets no tracking cookies, and uses no external fonts. See our privacy policy for the full statement.
The catalogue lives in a separate open-source package called the Playbill (codeberg.org/ConsentTheater/playbill, published on npm as @consenttheater/playbill). Every entry is public so the claims are auditable. Sources for each tracker are documented in the entry where possible.
Open an issue or pull request against the Playbill repo, or email developer@consenttheater.org. Corrections are welcome — that is the whole point of keeping the catalogue public and auditable.
Star the project on Codeberg — it genuinely helps people find it. Beyond that: add or correct catalogue entries in the Playbill, file bugs, improve documentation, or contribute to the browser extension. The project is volunteer-run; there are no paid roles and there's no investor pressure to deliver anything you don't want to.
We develop on Codeberg — a non-profit, community-run home for free and open-source software, which suits a privacy project better than a big commercial platform. If you prefer GitHub, we keep a read-only mirror there so you can still browse and follow along. Just open issues and pull requests on Codeberg, since that's where the work happens.
No. Everything on this site is for educational use only. ConsentTheater is not a law firm and is not affiliated with any regulator. For a GDPR or ePrivacy assessment on a specific situation, talk to a qualified lawyer or DPO.
