This extension does not collect, store, or transmit any personal data.

All communication occurs locally between the Firefox extension and the Cove Download Manager desktop application using Firefox's native messaging system (stdin/stdout). Cookie and referrer information is forwarded only to the local aria2 download engine when required for authenticated downloads.

No user data is sent to external servers, shared with third parties, or stored outside of the local system. The extension's sole purpose is to pass download requests from Firefox to the locally installed Cove Download Manager application.
