Context Search Origin does not collect any data of any kind.

Context Search Origin stores nothing but the extension preferences in your browser profile. Not even the search engines you add for use in Context Search Origin, as they are stored as Firefox bookmarks.

Favicons (website icons) are fetched from a remote server (Google S2) in real-time via secure connection (HTTPS). You can opt out of using this service in the extension preferences by unchecking "Enable favicon fetching (Google S2)". Google's Privacy policy (https://policies.google.com/privacy) may apply if favicon fetching is enabled.
