iPhone

Open .bge files from Files or other apps, decrypt and preview them privately, then encrypt or share with identity cards. On-device, no accounts, your keys stay yours. 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. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdfla/ Privacy Policy: https://dotbge.app/privacy
