What you are agreeing to
- The browser will ask you to let this extension read history and cookies, limited to the … domains listed below: the Discover-Tech network plus the mainstream ad platforms the report names, which are shown separately as context. It cannot see any other site.
- History is searched for those domains only. Cookie names are noted; cookie values are never read.
- Nothing is uploaded. The only network request is the download of the public indicator list.
- Access is removed again when the scan finishes, unless you choose to keep it.
- Clearing history or cookies before scanning hides past visits, so a clean result is not proof.
Domains that will be checked
Live monitoring
Watches as you browse and alerts you if this browser contacts an indicator domain. To deliver requests made by other sites' ads, the browser requires access to all websites, which it words as reading your data on every site. The extension asks the browser to hand it only requests to the indicator domains, never reads page content, and stores or sends nothing else. The source is open to inspect.
Off
- Each alert records the indicator domain, when, and which site you were on. That stays on this device.
- Reporting to the Leah Files is off by default. When you turn it on, or press Send on one alert, the only data sent is the published indicator and the word "live", for example
{"indicator":"fearevolve.com","origin":"live"}. No page, URL, time or identifier is sent. Like any web request, it shows your IP address to our server, which does not store it.
