Encrypted file vault

Your files, your rules

Every private file you share lives in your encrypted vault. Browse, re-share, revoke access, or delete, all from one place. The server never sees your data in plaintext.

Private Upload

Encrypted

Files are encrypted on your device with AES-256-GCM before upload. Stored in a private bucket with per-file permission controls. Tier-based size and storage limits apply.

Public Upload

Unencrypted

Files are uploaded as-is to a public CDN and embedded as direct links. Fast and convenient for non-sensitive content like memes, screenshots, or public media. 10 MB limit for all tiers.

How the vault protects your files

Private files are encrypted before they leave your device and stay encrypted at rest.

Client-Side Encryption

Every private file is encrypted with AES-256-GCM on your device before it ever leaves. The server stores only ciphertext; even Cloak cannot read your files.

Granular Permissions

Share encrypted file keys with specific users or entire rooms. Revoke access per-user or per-room at any time, without re-uploading.

Zero-Knowledge Storage

File keys are wrapped with your password-derived key and stored alongside the encrypted data. Without your credentials, your files are unreadable by anyone.

Full lifecycle control

Upload a file once, share it anywhere: DMs, rooms, or new conversations. Grant and revoke access on a per-user or per-room basis without re-uploading. Delete a file from the vault and it's gone from every conversation it was shared in.
