Competitive Companion extracts problem data from online judges. This only happens when the user triggers the page action. The extracted problem data does not contain personal data.
The extracted problem data is shared with various ports on localhost. These are port 4243, the ports in this file and any custom ports specified by the user in the extension's settings. Extracted problem data is never sent to non-localhost hosts.
