Is Simple Translate safe?

Clean risk

Simple Translate reads selected page or form text and sends it to Google Translate for language checks and translation.

Simple Translate runs a content script on all pages and listens for mouseup after text selection, excluding password fields. With the default Google translation setting, it can send selected text, including non-password form input, to translate.googleapis.com to check the language and provide translations.

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.
