The private Discord alternative, encrypted by default
Rooms, roles, voice, video, and file sharing, wrapped in end-to-end encryption. Your data never leaves your device unencrypted.

- Key exchange
- X25519
- Message cipher
- AES-256-GCM
- Calls
- WebRTC Insertable Streams
- Server knowledge
- Zero
Full feature set. Zero compromise.
Everything Discord does. Nothing Discord sees.
MESSAGING
Chat like nobody’s watching. Because nobody is.
Every message is sealed on your device before it leaves: DMs, group DMs, and rooms, with replies, reactions, GIFs, and custom emoji. The server relays ciphertext it can’t read.
- Encrypted DMs, group DMs & rooms
- Replies, reactions, pins & full-text search
- Disappearing messages with per-channel timers

VOICE · VIDEO · SCREEN
Calls that stay between you.
Voice channels, camera, and screen sharing with every frame encrypted before it touches the relay. The relay never holds a key, and your IP address is never exposed to the other people in the call, on every plan.
COMMUNITIES
Run it like a real community.
Rooms with channels, categories, roles, and fine-grained permissions. Invites, moderation, audit logs, webhooks, and bots. The structure Discord taught everyone, minus the surveillance.
- Roles with granular, per-channel permissions
- Invites, moderation tools & audit logs
- Custom emoji, webhooks & flow automation

Calendar
Plans that don’t leak.
Shared calendars live right inside your rooms. Schedule events, set recurring meetings, collect RSVPs, and send reminders, with event details encrypted end to end like everything else.

Every screen
One account, every device.
The same encrypted rooms, calls, and files on the desktop app and the web today. iOS and Android, with a full multi-pane layout on tablets, are on the way.

The rest of the toolbox.
Everything you’d expect from a modern chat platform, and a few things you wouldn’t. All of it built on the same zero-knowledge foundation.
Encrypted file vault
Client-side encrypted storage, shared per room.
Group DMs
Private group chats with their own keys.
Notifications
A unified feed, push, and granular mutes.
Achievements
Badges to earn and show off on your profile.
2FA & devices
TOTP, session management, remote sign-out.
Custom emoji
Upload your own or import a whole pack.
Search
Find any message, indexed on your device.
Nicknames & aliases
Per-server nicknames and private aliases.
QR device linking
Add a device by scanning, keys handed off sealed.
Blocking & reporting
Cut someone off and destroy the shared keys.
Bots & webhooks
Automate with flow bots and inbound webhooks.
Discovery
Find public communities in the Explore directory.
Security architecture
“Trust us” isn’t a security model.
Cloak is built so that trusting us is unnecessary. Encryption happens before your data leaves your device, keys stay with you, and the server’s job is to move ciphertext, not to understand it.

What is Cloak?
Cloak is a privacy-first Discord alternative with the features you actually want. Create or join encrypted chat rooms with text and voice channels, set up roles and permissions, react to messages, share files, hop on encrypted video calls with background effects, and customize your experience with themes and appearance settings. All protected by end-to-end encryption and zero-knowledge architecture, making it the secure messaging app for people who refuse to compromise.
How does Cloak protect my privacy?
Unlike Discord or other mainstream chat apps, Cloak uses modern public key cryptography (X25519) for key exchange and AES-256-GCM to encrypt every message on your device before it reaches the network. The server only ever sees ciphertext, never plaintext. Voice and video calls are also end-to-end encrypted using WebRTC Insertable Streams. Your encryption keys are stored locally on your device, so even we cannot read your messages, files, or calls. This zero-knowledge architecture is what makes Cloak a truly private chat app.
What platforms is Cloak available on?
Cloak is available as a desktop app for Windows, macOS, and Linux, plus a web app at app.cloak.chat. Apps for iOS and Android are on the way. Desktop and web app users can subscribe and manage their plan right in the app; this website handles the same thing for anyone on a phone.
How do group chats and rooms work?
Rooms are encrypted spaces with text and voice channels, just like servers on other platforms. You can create roles with granular, per-channel permissions, upload custom emoji, generate invite links with optional expiration, view audit logs, and set AFK timeouts. Room owners can cycle encryption keys at any time. Free users can join up to 2 rooms, while paid tiers support 20 to 200 rooms.
What are the limitations for voice and video features?
Voice channels have no strict limit on participants and all voice and video is end-to-end encrypted on every plan. Every frame is encrypted on your device before it is sent, the relay never holds a key, and your IP address is never exposed to the other people in the call. Free users can turn on their camera or share their screen at 720p30, one at a time, in channels of up to 10 people, and can watch one stream at up to 720p30 plus small previews of up to three others. Paid tiers can run camera and screen share together with screen share up to 1080p60, and watch more at once: Basic 3 streams at 720p30 or 1 at 1080p60 plus 6 previews, Plus 8 or 1 plus 5 at 720p30, and Pro 16 or 1 plus 13 at 720p30. One to one calls always allow camera and screen at the same time. Screen sharing is available on desktop and web.
How much does Cloak cost?
Cloak offers four tiers: a Free plan with up to 2 rooms, 1GB encrypted vault storage, 720p30 video and screen sharing, and core privacy features; a Basic plan at $6.99/month with 20 rooms, 10GB storage, and camera plus screen share together at up to 1080p60; a Plus plan at $14.99/month with 100 rooms, 25GB storage, and more streams at once; and a Pro plan at $29.99/month with 200 rooms, 100GB storage, and the most streaming capacity. Every plan uses the same end-to-end encryption.
What storage limits and file sharing options are available?
Cloak offers two upload modes. Public uploads go to an unencrypted CDN as direct links (10MB limit, all tiers), great for non-sensitive content. Private uploads are encrypted on your device with AES-256-GCM before upload and stored in your encrypted vault with tier-based limits: Free gets 1GB with 10MB files, Basic gets 10GB with 50MB, Plus gets 25GB with 200MB, and Pro gets 100GB with 500MB. The vault lets you browse every private file you’ve shared, manage per-file sharing permissions for specific users or rooms, revoke access, and download or delete files from one place.
How long are messages stored?
Paid users (Basic, Plus, and Pro) can choose if and how long their direct messages persist. All messages are stored as encrypted data that can only be decrypted on authorized devices. The server never has access to plaintext.
