Is HyperChat [Improved YouTube Chat] safe?

Clean risk

HyperChat sends YouTube live chat text to kentonishi.com when message translation is enabled.

HyperChat includes an optional translation feature for YouTube live chat. When a target language is set, it embeds a translator iframe from kentonishi.com and posts chat message text to that iframe for translation.

Shared hosts - 2 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.
