Is Competitive Companion safe?

Clean risk

Parses competitive programming problems and contests for use in supported coding tools.

This extension reads supported online judge problem pages and sends the parsed problem data to tools such as CP Editor and CPH. Users can click the green plus icon or use the Ctrl+Shift+U shortcut, and on supported contest pages it can parse all problems in the contest at once.

Shared hosts - 5 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
