Hide photos, videos and documents, not just tuck them away
Hidden albums only hide thumbnails. NumVault moves the files themselves into an encrypted vault, so they are scrambled on disk and invisible to other apps.
Photos
Private pictures and screenshots, removed from your camera roll after import if you choose.
Videos
Clips you do not want in your library or in cloud photo sync.
Documents
PDFs, contracts, medical letters, tax files and notes.
IDs and scans
Passport, driving licence and card scans kept off your gallery.
Three ways to get files into your vault
Share from any app
Tap Share in Photos, Files, Slack, Teams, Messages or Mail and choose NumVault. The file goes straight into the vault.
Import from your library
Pick photos and videos from your library. NumVault encrypts them and can remove the originals so nothing is left behind.
Shoot straight into the vault
Take photos inside NumVault. They are encrypted immediately and never touch your camera roll.
Face ID and Touch ID
Optional second step after your code.
Multiple vaults
Keep work, family and personal files apart, each with its own code.
Encrypted backup
Back up to iCloud or Google Drive. Files are encrypted before upload.
Your files are encrypted with AES-256 before they are stored
AES-256 is the encryption standard used by banks and governments. NumVault applies it to every file on your phone, so what is stored is unreadable without your keys.
- Each file has its own random 256-bit key (AES-256-GCM)
- Keys are protected by your phone’s secure hardware
- Backups are encrypted on your phone first, so iCloud and Google Drive only see scrambled data
- We have no servers that can read or recover your files
Bonus: make NumVault look like a calculator
Turn on the calculator disguise and the app opens as a fully working calculator. Type your secret code, press “=”, and your vault opens. Anything else just calculates. You can also change the home screen icon.
The disguise is optional and clearly explained in the app and store listing. It adds discretion, while the encryption is what protects your files. What is a calculator vault app?

Your files always stay yours. If you stop paying you can still open and export everything.

Questions about hiding files in NumVault
Can I really hide photos and files with NumVault?
Yes. You move photos, videos and documents into the vault from your photo library, the camera or the Share menu of any app. They are encrypted and no longer show up in your camera roll or file browser. You can also ask NumVault to remove the originals from Photos after import.
How are my files encrypted?
Each file is encrypted on your phone with its own random 256-bit key using AES-256-GCM, an authenticated mode that also detects tampering. Those keys are protected by a master key kept in your phone’s secure hardware. Your files are never uploaded in readable form.
Do I need an account?
No. There is no sign-up, no email and no password to remember on a server. Your vault lives on your device. We have no servers that can read your files.
What happens if I forget my code?
We cannot reset it, because we cannot read your data. That is why NumVault asks you to save a recovery key when you create your vault. With the recovery key you can open your vault again.
What if I lose or change my phone?
Turn on encrypted backup (iCloud on iPhone, Google Drive on Android) or export an encrypted .numvault file. The backup is encrypted on your phone before it leaves it, and you restore it on the new phone with your recovery key.
Is the calculator disguise required?
No. It is an optional extra for people who want more discretion. When it is on, the app looks and works like a calculator, and your secret code followed by “=” opens the vault. The encryption works the same with or without it.
What can I store in the vault?
Photos, videos, PDFs, scanned IDs, screenshots, documents and most other files. You can add several at once, and files you receive in Slack, Teams, Messages or Mail can be sent straight to NumVault with the Share button.
Is NumVault free?
You can start free with one vault and up to 10 items. NumVault Pro is $2.99 per week or $44.99 per year and adds unlimited items, up to five vaults, a decoy vault and encrypted cloud backup.
What if I cancel Pro?
Your files stay yours. You can still open, view and export everything. Only adding new items beyond the free limit stops.
Can someone with my unlocked phone open the vault?
Not without your code, and optionally Face ID or Touch ID as a second step. The vault locks itself when you leave the app. NumVault protects against casual snooping and a lost or stolen phone, but no app can protect you if your phone is already compromised by malware.
