Does TrackBlock send data to servers?
No. TrackBlock does not send any data to external servers. All tracker detection and analysis is performed entirely within your browser. We do not use analytics services, telemetry, or remote processing of any kind.

No. TrackBlock does not require any account, registration, or login. Simply install the extension and it works immediately. There are no accounts because there is nothing to store on our end.
