Only for iPhone

iPhone
If someone opened your phone right now — what would they see?
Your photos. Your documents. Your private life.
One tap is all it takes.
Fort Knox makes sure that never happens.
Real Protection. Not Just a Hidden Folder.
Most "private photo" apps are just folders with a password. Easy to open. Easy to fail.
Fort Knox is different. It's built like a vault.
- Face ID & Touch ID — only you can unlock
- Secure PIN protection
- 100% local storage — nothing ever leaves your device
- Stealth mode — hide the app in plain sight
- Break-in alerts for every unauthorized attempt
Because privacy should never depend on luck.
What happens when someone tries to get in?
You don't just block them. You expose them.
- Intruder Selfie — captures anyone entering the wrong PIN
- Instant alerts — know the moment it happens
- Fake Vault (Premium) — show harmless content if you're forced to unlock
No guessing. No blind spots.
Everything Private. One Secure Place.
- Photos & videos
- Documents, IDs & passports
- Audio recordings
- Personal notes
Import from Photos and Files, or capture directly in the app — so sensitive content never appears in your gallery.
Fast. Simple. Under Your Control.
- Secure folders and subfolders
- Tags, comments & smart metadata
- AI-powered keyword suggestions
- Lightning-fast search across every file
Find what you need instantly — and keep everything else hidden.
Unlock Full Protection
The free version gets you started. Premium makes you truly secure.
- Unlimited storage — no caps on files, folders, or subfolders
- PIN-protect individual folders — extra security for your most private content
- Fake Vault with separate PIN — show decoy content under pressure
- Built-in PDF document scanner — capture IDs and papers directly into your vault
- Trash, watermark-free exports, and smarter import — every detail polished
Because partial protection isn't protection.
100% Private by Design
Your data stays on your device. Period.
