Features
Tools for people who prefer not to explain themselves
End-to-end encryption
Pick E2E mode and your browser encrypts the blob before upload. Server sees ciphertext only. Keys never leave this tab.
Content-addressable storage
Server-mode blobs are encrypted with a master key and addressed by plaintext hash. Two copies of the same file share one byte of disk.
Encrypted folders
Group files under one password. Share the whole folder with a single link — viewers unlock with the folder password, not individual file keys.
Public share links
Every file and folder gets a short slug. Shareable to anyone; decryption still needs the password you set.
Invite-only
Registration requires a code. Each user mints 6 invites. No bulk signups, no random visitors.
Bot-resistant by default
Hard-bot UAs get a 403. Everyone else solves a proof-of-work captcha once per 7 days. Human gate, not a paywall.
Threat model
What the server can see. And what it absolutely cannot.
Visible to the server (server-mode)
- Plaintext during the upload request itself
- Your encryption password (hashed with argon2)
- File size + MIME type in the database
- Decrypted bytes on demand, using a server master key
Never visible (E2E mode)
- Plaintext — encryption happens in your browser
- Your password — it never hits the wire
- Derived encryption keys — only the client holds them
- Cross-user dedup — requires same (file, password) pair
Flow
Three steps
Upload
Drop any file up to 500 MB. Pick E2E (browser-side) or server-side, set a password, hit go.
Encrypt
AES-256-GCM with chaos-derived keys seals the bytes. The original plaintext leaves memory as soon as the upload completes.
Share
Copy the generated slug. Recipients enter the password to decrypt. No password, no access — not even for us.
