Does my writing get sent somewhere?

Yes — checking grammar needs a language engine, and this uses the public LanguageTool service. Do not paste anything confidential. An administrator can point it at a self-hosted server instead.

Why does it flag correct sentences?

Style rules are suggestions, not errors. Deliberate fragments and technical terms often get marked — that is why nothing is applied automatically.

Which languages does it check?

English and around twenty more, including German, French, Spanish and Portuguese. It detects the language of what you paste.
