A private, self-hosted file-sharing suite that works across iOS, Android, Windows, macOS and Linux, with a post-quantum end-to-end encrypted messenger and calls built in. It is a single app that replaces both a cloud drive and a secure chat, from one shared codebase.
Move files between any of your devices, mirror your phone storage, and talk to people securely, without handing anything to a third-party cloud.
Highlights
- Truly cross-platform: iOS, Android, Windows, macOS and Linux from one codebase.
- Post-quantum end-to-end encryption for messages and calls (ML-KEM-1024, Dilithium5, XChaCha20-Poly1305) with safety-number verification.
- Cloud-drive experience with a bidirectional phone-storage mirror, background sync and offline files.
- Powerful sharing: direct shares, expiring codes, password-protected public links and recipient-locked links.
- Voice and video calls (WebRTC) with post-quantum-derived keys and CallKit hand-off on iOS.
- Business workspaces: multi-tenant organisations, roles, encrypted group channels, quotas and audit logs.
Built with Flutter, Go, Rust, WebRTC, Kyber-1024, Dilithium5.
