FastForward does not collect any personally identifiable information on its users. The only information collected is what is described below, in the Auto updating and Crowd Bypass sections.
This section does not apply to Firefox.
In order to provide up-to-date bypasses, FastForward sends a request to Github every hour, and if a new commit is found, it will download the latest "injection script."
When Crowd Bypass (Options > "Give and take the destinations of unbypassable shorteners.") is enabled, ocassionally the extension will send requests to our server.
