| Date | What changed |
|---|---|
| 2026-10-24 | Initial launch. |
| 26.10.2026 | Six new guides: turning on Global Privacy Control in every browser, fingerprinting techniques, Tor Browser, Google's 2025 fingerprinting policy, incognito mode and VPNs against fingerprinting. Clearer titles for the test and the main guides. |
| 26.10.2026 | Review fixes: the home page now says it is based on Mozilla and EFF guidance rather than written by them. "What is fingerprinting" merged into the techniques page; the reduction page became a defence-by-technique table; the Firefox GPC steps now live on one page; the California sweep now names all three Attorneys General. |
