Hyderabad, Telangana, India
What it is
Blackbox is a mobile app for keeping photos, videos, files, notes and other content in encrypted vaults. Vaults can use a PIN, pattern match or piano sequence, while a decoy PIN opens a separate vault with harmless content if someone forces an unlock. The maker says AES-256 encryption takes place on the device before data is transmitted. The free version has a limited number of vaults, PIN-only unlocking, local storage and ads. Premium costs $12.99 a month and adds unlimited vaults, advanced unlock methods, cloud sync, base cloud storage and an ad-free experience. Premium users can sync encrypted vaults to iCloud Drive, Google Drive or Blackbox Cloud; cloud sync is disabled by default. The app is available for Android and iOS through Google Play and the App Store. The maker says it cannot recover vault data if a user forgets the PIN, so retaining the unlock details is important. Support is available at [email protected].
For and against
For
- Vaults can hold photos, videos, files and notes
- Decoy PIN opens a separate harmless-content vault
- Maker says encryption uses AES-256 on-device
- Premium supports three cloud storage options
Against
- Free version is limited to PIN unlocking
- Free version includes ads
- Forgotten PIN means vault data cannot be recovered
The verdict
Blackbox provides local encrypted vaults, with cloud sync available to Premium users and disabled by default. Because the maker cannot recover vault data after a forgotten PIN, preserving unlock details matters.
Who it suits
Blackbox suits mobile users who want to keep private files and notes in protected vaults. Premium may suit users who want cloud sync or unlock methods beyond a PIN.
