Capture into the vault
Shoot photos and videos with the built-in camera and they’re encrypted on the spot — the originals never touch your camera roll.
Krypta is an encrypted vault for the photos, videos, documents and notes you’d rather keep to yourself. Locked behind a PIN, encrypted with the same cipher trusted by security professionals — and they never leave your phone.
Krypta
Most “private” apps quietly send your files to a server. Krypta has no server to send them to.
Encryption happens on your phone, with a key only your phone holds. Even we couldn’t read your vault if you asked us to — there’s nothing to read.
Pull in anything sensitive, view it without ever decrypting it to the camera roll, and keep your most private notes sealed alongside it.
Shoot photos and videos with the built-in camera and they’re encrypted on the spot — the originals never touch your camera roll.
Open images, play videos and audio, and read PDFs right inside Krypta. Files are decrypted to a private cache and wiped the moment you lock.
Passwords, codes, private writing — stored inline inside the encrypted index. No separate file, no plaintext ever written to disk.
Scan paper documents with edge-detection and multi-page support, combined into a single encrypted PDF without a plaintext copy left behind.
A second PIN opens a harmless decoy vault. Turn on intruder capture and a wrong PIN silently snaps a front-camera photo, just for your eyes.
Optionally back up to your own Google Drive. The archive is encrypted on your phone first — Google only ever stores ciphertext it can’t read.
Krypta uses layered “envelope” encryption bound to your specific device, so a stolen vault file is useless without the phone it came from.
Deliberately slow and memory-hard, so guessing is expensive even with the file in hand.
A hardware-backed secret that never leaves the phone — this is what makes offline brute-force impossible.
Every file gets its own data key. Changing your PIN re-wraps one key — your files are never re-encrypted.
Authenticated encryption in independent chunks — tampering, reordering or truncation is detected and rejected.
No home-grown crypto. Krypta builds on libsodium — the same well-reviewed library used across the security industry.
No sign-up, no email, no waiting on a verification code. Set a PIN and you’re in.
On first launch you create the PIN that unlocks your vault. There’s no account and nothing to remember beyond it.
Import from your gallery or files, capture with the camera, scan a document, or jot a secure note. Each is encrypted as it lands.
Krypta auto-locks and wipes its decrypted cache. Re-open, enter your PIN, and everything is right where you left it.
Backup is always optional and always encrypted before it leaves your device. Choose the recovery method that fits you.
Nothing extra to memorise. Restore on a new phone with the same PIN you already use.
A one-time secret phrase protects the backup independently of your PIN — for the most security-conscious.
Krypta has no ads, no subscriptions, and collects no data. It’s kept free by people who chip in. If it protects something you care about, you can help keep it going and fund what’s next.
Download Krypta and put a real lock on your most personal files — encrypted on your device, answerable to no one but you.
