DotBGE
100% on-device secure file encryption and sharing tool.
What it does
Encrypts files and folders directly on-device using RSA-4096 and AES-256-GCM without cloud server involvement. Shares contact identity cards via QR codes or file exports to enable secure peer-to-peer file encryption. Locks local file vaults behind Face ID or Touch ID protection with optional private iCloud synchronization. Previews decrypted documents, photos, and media directly inside the app without writing unencrypted copies to disk.
Why it works
Local-first processing guarantees zero cloud tracking or account dependency, keeping complete control in user hands. Open .bge file format ensures data portability across devices without lock-in to proprietary services. Identity card sharing removes the friction of swapping complex raw cryptographic strings manually. Freemium tier availability drives low-barrier mobile utility adoption via the iOS App Store.
