That means your confidential discussions - therapy sessions, doctor visits, legal consultations, salary negotiations, business strategies - travel through the internet and sit on someone else's computer indefinitely. Private Notes - AI Note Taker is different. We built this offline note taker from the ground up to be 100% local and on-device. No compromises. No "mostly private" half-measures. Paid users who want backup can enable optional iCloud sync - encrypted by Apple, with no third-party access. Sync is off by default, and we still can't see your data. When you delete a recording, it's gone forever - because we never had access to it in the first place.
