End-to-end encrypted cloud storage where even we can't see your data. No backdoors. No compromises. Ever.
Your passphrase never leaves your device. We derive keys locally, encrypt locally, and only send ciphertext to our servers. We are architecturally blind to your data.
Military-grade cryptography meets modern cloud storage. Fast uploads, seamless sharing, and zero compromises on security.
XChaCha20-Poly1305 encryption with Argon2id key derivation. Your passphrase is never transmitted or stored.
Store on AWS S3, Cloudflare R2, Backblaze B2, or MinIO. Switch providers anytime — no vendor lock-in.
Files split into 4 MiB encrypted chunks for parallel uploads, resumable transfers, and efficient bandwidth use.
Share files with X25519 key agreement. Recipients decrypt with their own keys — we never see the content.
Web app, desktop (Tauri), and mobile (React Native). Your encrypted vault, everywhere.
Client code is fully open source. Every cryptographic operation is auditable. Trust is verified, not assumed.
Transparency isn't a feature — it's a requirement. Here's exactly what our architecture makes possible, and what it makes impossible.
No custom cryptography. No security through obscurity. Every algorithm is an industry standard, independently auditable.
Argon2id
Memory-hard, GPU-resistant
XChaCha20-Poly1305
256-bit, AEAD
X25519 + HKDF
Elliptic curve Diffie-Hellman
BLAKE3
Faster than SHA-256, equally secure
No hidden fees. No data mining. You pay for storage, not for us to exploit your data.
5 GB encrypted storage
200 GB encrypted storage
2 TB encrypted storage
Join the waitlist for early access. We'll never share your email — that would be ironic.
