GalleryVault vs NullVault

GalleryVault is an Android and iOS app for keeping photos, videos, and other files in a private vault. Users can add or capture photos and videos; supported file types also include audio and documents. The maker describes stored files as encrypted, and says media on SD cards can be encrypted too. A private browser can download all images and videos from a web page with one tap. For disguised access, the app can hide its icon and provides a secret door. GalleryVault includes backup and restore, and its help page says it can connect to Google Drive to store encrypted files. Free users can upload up to 100 new files to Google Drive per month. The maker says data is kept on the user's device and recommends backing it up. Deleted photos remain in the recycle bin for 60 days before automatic deletion. Paid features include fingerprint unlock, folder lock, fake passcode, random PIN keyboard, shake-to-close, and break-in alerts. A free plan is listed; the seven-day trial applies to six-month and one-year subscriptions. Paid options include 9.90 CNY a month and 68 CNY a year.

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.
