Are my Auth0 tokens sent anywhere?

No, all decoding happens locally in your browser ensuring your Auth0 credentials remain secure.

Can I verify the signature?

Decoding and signature verification are different steps. You can see the claims without the private key.

Auth0 JWT Decoder is designed to run in the browser. Review outputs before sharing them with any external service or workflow.
