Is Ban Checker for Steam safe?

Low risk

Ban Checker for Steam sends Steam Web API keys to api.steampowered.com when checking ban status.

When the extension checks Steam accounts for bans, it uses a bundled default Steam Web API key unless you configured your own. The background worker sends that key with the Steam IDs being checked to Steam's GetPlayerBans API at api.steampowered.com.
