When you translate an email, the text content of that email is sent to the translation service you selected in the extension settings. No other data (headers, sender, recipient, subject, attachments) is transmitted.
Depending on the translation provider selected in Settings:

See their privacy policy.api-free.deepl.com, operated by DeepL SE (Germany).
See their privacy policy.Translated results are cached locally in your Thunderbird profile using the browser's
storage.local API. This data never leaves your device and is not accessible
to the extension developer.
