LanguageTool is owned by a German business (GmbH), but operates under an international business called Learneo (Inc.). The privacy policy is with Learneo and does include data transfer to the US. It's unclear to me whether they operate [with the data] in the US or if that is only for specific or secondary operations and support.

LanguageTool uses third-party US analytics (Google Analytics and Amplitude.

LanguageTool is Open Source, but self-hosting does not include any of the AI features/rules.

DeepL is a German business. The free tier processes your data for training, and you must not submit any personal data.

Do you know of other alternatives that go beyond simple dictionary spell-checking, similar to these services? Ready-for-use service, local, or self-hosted.

Antidote. From Druide Informatique is a great set of spellcheckers (and gramamtical guides) for French and for English.

Alas, a few years ago they dropped their Linux version. Also, it's not from the EU but from Canada... which has not yet been invaded by the USA.

Edit: too many things to list, I'm tired (and I don't have Antidote on my Linux machine)

Tracking integration of Google, Meta - presumably on their website only.

Data transfer to Canada (I checked to make sure they don't transfer to the US despite being based in Canada).
