RevaultAn account-free mobile photo vault that encrypts photos, videos, filenames and thumbnails on-device. Choose private previews, recovery and optional sync.
Download RevaultSecurity modelRevault is a native photo vault for iPhone and Android. Photos and videos are encrypted on your device with AES-256-GCM before they are stored, along with their filenames and thumbnails. Each vault opens with its own pattern, and you keep the recovery key, so there is no master key on our side to hand over or leak.
In the next iOS and Android update, video tiles show a poster frame and duration in grid and list views, including inside folders. New imports and edited videos save these details encrypted with the file. Existing local videos are filled in one at a time on the current page, decrypting only the parts needed in memory without writing a decrypted copy to disk. Unavailable files or unsupported codecs keep their fallback icon.
The native iOS and Android apps need no Revault account, email or sign-up. Vaults stay local unless you choose a cloud provider, share or export. The apps are coming soon to the App Store and Google Play.
A vault can’t protect an unlocked phone from malware, and the service can still see file sizes and timestamps. Revault has not had an independent security audit. Everything we do implement is documented in our security model.
Look for a published encryption mode and key design, keys that stay with you, encrypted filenames and thumbnails rather than only the images, a recovery path the provider cannot use, and a clear account of what remains visible. Revault documents each of these in its security model.
Each vault has a random 256-bit AES master key. Your pattern combines with a random device secret to wrap that key. File contents use HKDF-SHA-256 streaming encryption with authenticated AES-256-GCM segments, and filenames, thumbnails and folder information are encrypted on the device too. A separate recovery key wraps the same master key.
No. The native iOS and Android apps need no Revault account, email or sign-up. Optional iCloud or Google Drive sync uses your own Apple or Google account.
Yes, on mobile. On Android phones, the plus button opens a bottom sheet with file imports, gallery selection, camera capture, new folders and vault creation. Android tablets keep the expanding menu. On iOS, use the plus menu to choose an import or capture action. Captures are encrypted into that vault and do not automatically enter your device gallery. You can also import selected items from Photos; the originals stay where they were.
Optional per-vault optimization can make newly imported photos and videos smaller before encryption, with Original, Balanced and Smaller modes. Files already in the vault and your source files are left untouched. Available device space still applies.
Turn on Break-in Alerts for a vault and, after three unmatched patterns, the app can take a front-camera photo. Alerts are encrypted, stored locally, and never uploaded or added to Photos. Safe Exit lets a designated vault’s pattern open that vault while removing other vaults’ local access from the device.
Create an encrypted share with its own key and send its secret separately. Controlled shares expire at a time you choose within 30 days, can limit access sessions, and can disable export. Recipients open the share in the Revault app without seeing your pattern or recovery key.
Revault for iPhone and Android is coming soon to the App Store and Google Play; it is not available to download yet. Revault is an independent app and is not affiliated with Revolut or similarly named products.
Revault keeps mobile vaults account-free and leaves the recovery key with you. Some photo vault apps favour email-based account access or cloud-first backup instead. The comparisons below set out the differences, with sources.
Moving a photograph out of an ordinary gallery can make it less visible during casual browsing. Encryption adds a protection boundary around the stored file and its private information. Revault encrypts the vault copy, filename and thumbnail on the device. It does not erase an earlier gallery copy, photo-provider backup or the version already sent through a chat.
A vault for original personal photographs may keep original import quality and use an independent encrypted backup. A smaller everyday collection might enable media optimization and favourites. A vault intended for selective sharing may also use metadata stripping and automatic random import names. These choices are separate: compressing a picture does not guarantee that its location metadata or visible identity clues are gone.
Import selected gallery items or capture directly inside the vault, then organize the collection with names, folders and tags. Use the thumbnail grid to browse images and list view to distinguish file details. Private preview actions let you edit, rename or share without first exporting to another app. Keep recovery material outside the phone so locking the collection does not make a lost device the only surviving route to your photos.
In the next iOS and Android update, video tiles show a poster frame and duration in grid and list views, including inside folders. New imports and edited videos save these details encrypted with the file. Existing local videos are filled in one at a time on the current page, decrypting only the parts needed in memory without writing a decrypted copy to disk. Unavailable files or unsupported codecs keep their fallback icon.
Android’s grid shows two thumbnail columns on compact screens and additional columns in wider windows, without file cards, filenames or action buttons. Scrollable underline tabs filter All, Photos, Videos, Documents and Audio while keeping your current search. Tap an image to open its private preview, or long-press for file options. Switch to list view when you need names and details beside the thumbnail. Folder names remain visible on one line, with tap to open and long-press for folder options.
In Android’s private preview, favourite, edit and encrypted-share actions sit in the bottom toolbar. The more icon opens an anchored menu for renaming, tags, supported metadata removal, moving, decrypted export and deletion. Long filenames stay on one line in the header. Marking a favourite keeps the preview open and saves without a progress popup; export remains an explicit action that creates a copy outside the vault.
Drag horizontally through the files in the folder, category, search or favourites view you opened: the current and adjacent pages follow your finger. Previous/next controls offer the same navigation, with a position counter. All file types stay in order; an unsupported format shows a safe placeholder and requires an explicit export to open elsewhere. At most one adjacent preview is prepared alongside the current page. Completed page changes release the previous temporary content; cancelled drags discard the incoming preview. Shared-vault navigation keeps the sender’s access rules in effect.
Android’s floating plus expands a labelled action menu above the button for creating a vault, importing files, choosing gallery items, taking a photo, recording video and creating a folder. Tap the plus again, tap elsewhere or use Back to collapse it. Short windows can scroll the actions without leaving the current screen.
Yes. The in-vault editor supports crop, rotate, horizontal flip, brightness and contrast with private working copies. Saving creates an encrypted PNG replacement inside the vault; it does not automatically create an ordinary gallery image.
Yes. They are part of the protected vault information. A cloud provider may still observe operational facts such as object sizes and transfer times. After you unlock, the app must temporarily decrypt the information it displays.
Yes. Leave optional sync disabled for that vault. Keep a separate encrypted backup because an offline-only collection can be lost with the phone. Explicitly creating a share or export is a separate decision to move a copy elsewhere.
Choose the settings that fit your files, and keep a recovery plan before you rely on a single device.
Download RevaultTake photos and videos inside an unlocked vault, import selected items from Photos, or send files from another app’s share sheet.
Make new photo and video imports smaller before encryption. Choose optimization settings separately for each vault.
Opt a vault into encrypted local photo alerts after repeated failed patterns. Review the evidence only after unlocking that vault.
