DotBGE encrypts files on-device with no accounts and no servers. Use the iPhone/iPad app to encrypt, decrypt, preview, and share .bge files; use the bge CLI on macOS/Linux for scripts and terminal workflows; or let Claude Code, ChatGPT, and other shell-running agents handle .bge files through the bundled skill. Built on the open .bge format with identity-based RSA encryption and password mode.
