Chrome/Firefox extension for Twitch (Frankerfacez, Better TTV, etc.) privacy safety

I would like to know if someone could tell me if there is any concerns for privacy in using one of those extensions (Frankerfacez, Better TTV, etc.) to add emotes to Twitch ?

When I went to the Chrome store, the privacy practices (personally identifiable information) seemed a bit risky to me.

Am I reading too much into this term (personally identifiable information) or is there a real risk for private informations ?

Thanks in advance 🙂
