Notebooks are stored on device by default. Cloud sync, if enabled, uses your account and encrypted object storage. We do not put note, PDF, OCR, or audio content into analytics or crash reports.
Purchases are processed by Apple, Google, and RevenueCat. Account deletion removes cloud account data we are not legally required to keep.
Ink, PDFs, recordings, and transcripts you do not sync remain local. Face ID locks guard the app door — they do not encrypt files on disk.
