“They're now forcing us to move to their garbage cloud service that has carve outs in their privacy policy allowing them access to notes and use for ai training. There's no opt out. Previously you could use encrypted storage on iCloud for cloud storage. Notability didn't like that. Now they're forcing everyone over to their own cloud to steal our document data. If you have sensitive information in notability, get out …”

Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
Professionals with sensitive documents fear vendor access to notes. Zero search volume masks real pain—this is driven by privacy policy changes at incumbents (Evernote, OneNote), not proactive search. Demand is reactive and episodic, likely concentrated after privacy scandals.
Competition & the opening
Minimal competition (1/10) on true E2E-encrypted notes is false comfort; Notion, OneNote, Evernote, and Apple Notes dominate. The gap is authentic: end-to-end encryption with zero vendor access. But most incumbents won't build this because it breaks their data-for-AI/monetization model.

What's hard to build
E2E encryption is well-solved cryptographically, but syncing encrypted data across devices without vendor key access is operationally hard. You lose search, analytics, and many features. Adoption friction is real—users must manage key recovery, and any mistake means permanent data loss. You also face credibility risk: crypto is easy to mess up, and one breach destroys trust.
Why now
Major cloud providers removing E2E opt-outs and claiming AI training rights; privacy-first note apps are now a category.
How you'd monetize
$4.99/mo for E2E sync (or one-time $29.99)
