DotBGE encrypts your files with RSA-4096 and AES-256-GCM, right on your device. No accounts, no servers, no cloud middleman — and it's built on an open format, so your files outlive the app.
Someone sent you an encrypted .bge file? Decrypting and previewing are always free — no purchase needed. Install DotBGE, authenticate, and open it.
Every feature runs locally. There is no dashboard to log into and no key to upload — the app simply works with the keys on your device.
Encrypt a file so that exactly one person can open it. Exchange identities with a QR code — no key servers, no email attachments of public keys, no trust-on-first-use guesswork.
A private store for sensitive files, protected by device biometrics and locked the moment you background the app.
No DotBGE on the other end? Seal with a passphrase — PBKDF2-SHA512, a million rounds.
View decrypted photos, PDFs, and video in-app — nothing is ever written back to disk.
Use the system share sheet to bring files into DotBGE on iOS and Android. On Apple devices, the Share Extension encrypts straight from Photos or Files, and optional iCloud sync keeps your vault across devices.
A .bge file made on one platform opens on every other. iPhone, iPad, Android, and the command line are available now; the macOS menu-bar app is on the way.
The .bge file is fully documented and free for anyone to implement. Your encrypted files are not locked to this app, this company, or any account. That is the whole point.
