The documented difference
Vaultaire presents an iOS local-first vault with pattern-addressed spaces, recovery phrases, optional encrypted iCloud backup and Pro device sync. Its site distinguishes interface privacy from countable encrypted index files. See Vaultaire’s official documentation.
Side-by-side decisions
| Question | NullVault | Vaultaire |
|---|---|---|
| Published platforms | iPhone and Android | iOS-focused product |
| Pattern processing described | Argon2id within the documented access design | PBKDF2 within its documented access design |
| Cloud question | Check the specific backup and sharing capabilities for your platform | Evaluate its documented iCloud backup and Pro device-sync workflow |
When Vaultaire is the better choice
Vaultaire may be the better fit when its documented iPhone-and-iPad device-sync workflow is a requirement. If you already depend on that workflow, verify any replacement feature explicitly before migrating.
When NullVault fits
NullVault is relevant when Android availability matters alongside iOS, or its particular recovery and local-vault behavior fits your needs. The key-derivation function name alone does not establish that one complete app is safer. Read NullVault’s features and security limitations for the released scope.
Before you move an archive
Try the same harmless archive and recovery exercise in each app. Compare what changes synchronize, what requires an explicit backup, and which phrase is needed after device loss. Do not treat matching marketing terms as proof of compatible backups.
