About

Kryptra

Features
Read full description

Keep your personal photos, videos and files together in a private, encrypted vault on your iPhone. Open Kryptra with a pattern you draw on a 5-by-5 grid, or enable Face ID for convenient access. ORGANIZE YOUR PRIVATE COLLECTION Create and rename albums, move items between them and mark favorites. Deleting an album keeps its files in your vault. Photos, videos and documents share one place, with no account sign-up required. IMPORT OR CAPTURE Use the central add button to import from Photos, choose files or open the camera. View your saved items and export or share selected files when you choose. Importing an original stored only in iCloud may require an internet connection. SEPARATE SPACES WITH PRO Set up a secondary vault or a separate decoy gallery with its own pattern and contents. Different patterns open different collections. These features do not erase your files. Pro also includes five alternate app icons and removes the free import limits, subject to available device storage. START FREE The primary vault includes up to 100 photos and non-video files combined, plus 10 videos. Each imported file counts toward its applicable limit. Pro is required to create additional vaults and add new items to them. If Pro ends, you can still view and export their existing contents. LOCAL STORAGE, CLEAR LIMITS Your vault files are stored encrypted on your device. Local viewing and organization work without an internet connection; purchases, purchase restoration and remote paywall configuration need connectivity. This version does not include cloud backup or synchronization. Keep exported copies of important files somewhere safe. Keep your nine-word recovery phrase safe. It can reset the pattern for encrypted files already on this device; it does not restore deleted files or transfer a lost vault to a new phone. Kryptra offers an auto-renewing annual Pro subscription and a lifetime Pro purchase. Available options and prices are displayed before purchase. Annual subscriptions renew unless canceled through your Apple subscription settings; deleting the app does not cancel a subscription. Use Restore Purchases to restore an eligible purchase with the same Apple Account. Kryptra uses subscription-screen analytics, purchase processing and diagnostics as described in its Privacy Policy. Vault contents, pattern and recovery phrase are not included in the app's first-party analytics events.
