If I opted in to share my data with the Ghostery Extension, is that data connected with my account?

No. Data shared with Ghostery through the opt-in program is solely related to tracking technologies that the user encounters – it is not connected with user accounts in any way.

No account needs to be created to use the Ghostery Extension; it is simply an option to make things more convenient for the user. However, an account will need to be created to access Ghostery Midnight.
