Passcode vs Encryption

Secret Photo Album protects your files with a passcode screen. Enter the correct code and the app displays your photos. This is access control, not encryption. The distinction matters: access control decides who can use the app, while encryption transforms the data itself into an unreadable format. If someone bypasses the app -- through a backup, file browser, or forensic tool -- access control is irrelevant because the files were never transformed.

Vaultaire encrypts each file individually using AES-256-GCM. The pattern you draw is not just a passcode -- it is an input to a cryptographic key derivation function that works with the Secure Enclave hardware. The resulting key encrypts each file separately, with its own initialization vector and authentication tag. Bypassing the app does not help because the data on disk is ciphertext.

File Accessibility Concerns

Because Secret Photo Album stores files in their original format, they are accessible through multiple vectors outside the app. Connect the device to a computer and browse the file system. Create an iTunes or Finder backup and examine the app's container. Use any third-party file management tool. In each scenario, the "hidden" photos are sitting there in JPEG, PNG, or MOV format, readable by any image viewer.

Vaultaire's container holds only encrypted blobs. Each blob is an AES-256-GCM ciphertext that includes an authentication tag for tamper detection. Browse the container all you want -- every file looks like random bytes. Without the pattern-derived key, there is no mathematical shortcut to recover the original content. This is the difference between hiding something under a mattress and locking it in a safe.

Data Migration Risks

Moving to a new device is where passcode-based vault apps consistently fail their users. Secret Photo Album stores files in the iOS sandbox, which may or may not transfer correctly during device migration, iCloud restore, or manual backup. Users report losing entire collections during phone upgrades because the sandbox data did not survive the transfer.

Vaultaire separates the encryption keys from the encrypted data. Your recovery phrase can regenerate the keys on any device. If you enable iCloud backup, the encrypted blobs sync automatically. A device migration with Vaultaire means: install the app, enter your pattern or recovery phrase, and your vault is restored. The encryption architecture makes migration a solved problem rather than a gamble.

プライバシーアーキテクチャ

Secret Photo Album's ad-supported free tier means the app includes advertising SDKs that collect device information, track user behavior, and transmit data to third-party servers. The app you trust with your most private photos is simultaneously reporting your usage patterns to advertising networks. This is a fundamental architectural contradiction.

Vaultaire contains no advertising SDK, no analytics framework, and no telemetry system. The app makes zero network requests by default. When you enable iCloud backup, the only network traffic is encrypted blobs sent to Apple's iCloud infrastructure. There is no server operated by Vaultaire, no data collection, and no third-party integration. The privacy architecture is 機能ではなく -- it is the absence of surveillance infrastructure.
