DotBGE: File Encryption

DotBGE encrypts your files right on your iPhone — no accounts, no servers, no cloud. Your keys stay yours.

Built on the open .bge format, DotBGE uses proven RSA-4096 + AES-256-GCM encryption to protect documents, photos, PDFs, and more. Share encrypted files with people you trust using identity cards, or lock everything with a password only you know.

▸ ENCRYPT FOR A FRIEND
Encrypt a file so that only a specific person's identity can unlock it. Add trusted contacts, then encrypt in a few taps — no passwords to exchange, no shared secrets to leak.

▸ IDENTITY CARDS, NOT RAW KEYS
Share your identity card via QR code or a .bgekey file so friends can encrypt files for you. No manual key swapping, no copy-pasting long key strings.

▸ PASSWORD MODE
No contact? Encrypt with a passphrase instead. Anyone with the password can decrypt — perfect for one-off sharing.

▸ OPEN .bge FILES FROM ANYWHERE
Open encrypted files from Files, Mail, or any app that offers a document handoff. DotBGE routes .bge files straight into a private decrypt-and-preview flow on iPhone and iPad.

▸ OPEN .bge FORMAT
Your encrypted files use a documented, self-describing container (BGE3). They're portable and not locked to any account or service — open them on iPhone, iPad, or Mac.

▸ FACE ID VAULT
Keep encrypted files close in a local vault, protected by Face ID / Touch ID. Optional iCloud sync keeps your vault available across your devices.

▸ PREVIEW AFTER DECRYPTING
View photos, PDFs, text, audio, and video right inside the app after decrypting — without writing decrypted copies to disk.

▸ ENCRYPT FROM ANYWHERE
Encrypt from your Photo Library, the Files app, or any app via the share sheet. Single files are always free to encrypt, preview, and decrypt.

▸ 100% ON-DEVICE & PRIVATE
Encryption happens entirely on your device. DotBGE has no account system and no servers — your files and keys never pass through anyone else's hands.

▸ DOTBGE PRO (one-time purchase)
Unlock batch encryption, folder encryption, an unlimited vault, and multiple identities. A monthly option is available for short-term projects. Decryption, preview, and single-file encryption are always free.

PERFECT FOR:
• Anyone sending sensitive documents to a specific person
• Privacy-minded users who want encryption without the cloud
• Professionals handling confidential files on the go
• People who want their own keys, on their own device

Encrypt your files. Keep your keys.
