Keepsafe Photo Vault vs NullVault

Keepsafe Photo Vault gives iPhone, Android and tablet users a protected place for photos, videos and documents. Access can use a PIN, fingerprint or Face ID, and users can arrange content in custom albums. The app can sync encrypted vault items to a private cloud for recovery or use on another device. Keepsafe says photos and videos are protected with 256-bit AES encryption at rest, backups are encrypted, and employees cannot view user content. The free Basic plan is ad-supported and backs up up to 200 items. Premium supports up to 10,000 cloud items on monthly or yearly plans, or up to 100,000 on Lifetime. Premium adds separately password-locked albums, a Decoy Vault, Intruder Alerts and Space Saver, which compresses photos on the device and stores originals in the cloud. Safe Send lets users share pictures from the vault for a limited time. New accounts are offered a 30-day Premium trial that Keepsafe says does not automatically charge when it ends. Premium costs $9.99 a month or $23.99 a year; both subscriptions renew automatically unless cancelled.

NullVault stores photos, videos, files, and notes in separate encrypted vaults, each opened with its own pattern. Entering a pattern opens the matching vault without showing a master list or the number of vaults. Within a vault, users can organize content into collections, search, and sort; they can capture or import items and deliberately export selected ones. Exported copies are outside NullVault’s protection.

Local vaults work offline without a NullVault account or server. The maker describes Android encryption using AES-256-GCM, Argon2id, and Android Keystore material; its iOS description lists AES-256-GCM, Argon2id, Apple CryptoKit, and libsodium. iOS supports encrypted iCloud backup and controlled read-only sharing through CloudKit, while Android supports portable encrypted backups. The free iOS plan allows up to five vaults and 20 items total, with one collection per vault. Compatibility is listed for iPhone running iOS 26 or later and Android phones running Android 10 or later. The maker warns that a compromised device may expose patterns, keys, screens, or plaintext, and that hidden vaults do not make encrypted data impossible to detect.
