Is Threads Translator - Automatic message and reply translation safe?

Low risk

Threads Translator sends the text of Threads posts to ext-api.com translation servers, in one mode over plain HTTP.

The extension reads post and reply text on threads.net pages and sends it to its translation backend to be translated. When the DeepL engine is selected for a logged-in pro user, the text and a temporary account token are posted to translate-api.ext-api.com over unencrypted HTTP, so anyone on the network path could read them.

Shared hosts - 1 hostname

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.
