See what loads when you open a page, how different kinds of blockers decide, what an app tracker report shows, and what a search reveals. Every site, company and app here is made up. The lab runs in your browser and sends none of your choices anywhere. Like every page on this site, it counts page views with the Foundation's self-hosted metrics, which use no cookies. Tools are named as examples, not recommendations.
A learning blocker watches which outside companies seem to track you across different sites. After it sees the same one on three sites, it blocks it. Visit the sites one by one.
| Outside company | Seen tracking on | Decision |

The right column describes how a metasearch engine such as PrivacySafe Search is designed, in its own words. Results can feel less personalized, and you still trust whoever runs the service, so read its privacy policy.

A report like this lists tracker code found inside an Android app, plus the permissions it asks for. Pick a made-up app.
A report shows that tracker code is present. It is not proof the tracker is active or that data was sent. Permissions are requests, and you can often decline them. Some trackers may be unknown to the tool.
Tools named here are examples, not recommendations. Extensions can read what you do on every site, so install only from the official source, from people or groups you trust. Do not change settings on a school or work device without permission.
