Private End-to-End Encrypted iCloud Sync
Keep your iPhone and iPad libraries synchronized with Vaultron Pro without registering an email account on third-party servers or exposing plaintext media to cloud providers.
Client-Side Encrypted Before Upload
Files are encrypted on-device into 256 KB AES-256-GCM chunks inside .vault containers, and catalog rows are sealed into authenticated encryptedMetadata envelopes before CKSyncEngine uploads a single byte.
Stored in Your Personal CloudKit Private Database
Records live strictly inside your own Apple Account private zone (iCloud.com.vaultron.app / VaultronEncryptedZone_v1) using EncryptedVaultItem records and CKAsset ciphertext streams.
Overnight Lock-Safe Outbox
Pending ciphertext uploads queue inside cksync_outbox.json so iOS BGProcessingTask wakes can finish large backups overnight while your device remains locked and charging, with no Master Key held in RAM.
One-Tap Remote Zone Purge
Return to local-only storage whenever you choose and permanently delete VaultronEncryptedZone_v1 and all local sync queues from Settings.

Questions & Answers
Can Apple or Treegarden Software Ltd view synced vault items?
No. Your Master Vault Key is never uploaded or escrowed. Without your vault credential or 12-word Recovery Phrase, EncryptedVaultItem assets and metadata envelopes cannot be decrypted.
