Someone sent me a .bge file. How do I open it?
Install DotBGE (it's free on the App Store), then open the
.bge file with it — from the Files app, Mail, or any share sheet. If the file was locked to your identity, authenticate with Face ID / Touch ID. If it used a password, enter the password the sender gave you. Decrypting and previewing are always free.I forgot my password. Can you recover the file?
No — and that's by design. DotBGE never sees your passwords or files, so there is no backdoor and no reset. If you forget the password used to encrypt a file in password mode, the file cannot be decrypted. Keep your passwords somewhere safe, like a password manager.
I lost my private key / got a new phone. Can I still open my files?
Files encrypted to an identity can only be opened with that identity's private key. If you enabled iCloud Keychain, your key syncs to your new Apple device automatically. If you did not back it up and it's gone, identity-locked files cannot be recovered. We recommend keeping iCloud Keychain on, and exporting a backup of important identities.
Does my data go to your servers?
No. DotBGE has no servers and no account system. Everything happens on your device. Optional sync uses your own private iCloud, managed by Apple — it never passes through us. See the Privacy Policy.
What's free, and what needs Pro?
Free forever: decrypting and previewing any
.bge file, encrypting single files (identity or password), one identity, a vault of up to 3 files, and the Share Extension. Pro adds: batch encryption, folder & structured encryption, an unlimited vault, and multiple identities.Should I buy Pro once or subscribe?
We recommend the one-time lifetime purchase ($24.99) — pay once, keep Pro forever, no renewals. A monthly subscription ($3.99) is available if you'd rather a lower upfront cost. Both unlock the same features.
I already paid. How do I restore Pro on a new device?
Open Settings → BGE Pro → Restore Purchases in the app, signed in with the same Apple ID you purchased with. Refunds are handled by Apple through your App Store account.
Can I sync my vault across devices?
Yes. Turn on Settings → iCloud Sync. Your encrypted vault, identities, and contacts sync through your private iCloud container so they appear on your other devices. It's off by default, and you can turn it off or erase the iCloud copy any time.
What encryption does DotBGE use?
Identity mode uses RSA-4096-OAEP to wrap a per-file AES-256-GCM key. Password mode derives the key from your passphrase with PBKDF2-SHA512. The container is the open .bge format (v3) — standard algorithms, fully documented.
Which platforms are supported?
iPhone and iPad (available now on the App Store). A macOS app and a command-line tool are in development, and because the format is open, third-party clients are possible too. A
.bge file made on one platform opens on every other.
