I'll get back to you. I'm not actually that worried about it, but I thought this would be a good opportunity to educate myself about how this works. I gathered NIP-44 use comes down to encrypting the aes key that encrypts the notes, and sync server stores encrypted notes and (nip44) encrypted aes key. I hope I got that right. There weren't any red flags from the robot, but I still have questions about "what if vinney were malicious?" Nature haha. Again, mostly for curiosity, not true fear.
