Feature rich, privacy focused

Every last message, secured by design

Cloak Chat offers a range of familiar features with security and privacy built in from the start.

The Cloak app showing encrypted servers, channels, and a live conversation
01

Secure messaging

Ordinary chat message bodies are end-to-end encrypted on your device. The service stores ciphertext and encrypted key backups; public sharing and integrations have separate privacy boundaries.

02

Servers & communities

Spin up servers with six channel types: text, voice, forums, calendars, whiteboards, and tickets. Threads keep side conversations beside the channel, and roles, fine-grained permissions, AutoMod, audit logs, and bot automation keep big communities manageable.

03

Encrypted file vault

Share files that are encrypted on your device before upload. Grant or revoke access per user or per server, with up to 100 GB of encrypted storage on Pro.

04

Make it yours

A full theme editor with gradient themes and share links, custom emoji, per-server nicknames, role icons, and achievements to show off on your profile.

Wait, you can do that?

No compromises, just features

VOICE · VIDEO · SCREEN

See and hear, privately.

High-quality voice channels, camera, and screen sharing on every plan. On desktop, share audio comes from just the app you are sharing, in clean stereo at music quality, no notification pings or mic bleed. Every frame is encrypted before it reaches the relay, the relay never holds a key, and your IP address stays private. Paid plans go up to 1080p60.

WHITEBOARDS

Draw together, live.

Whiteboard channels give every server a shared infinite canvas: live cursors, follow mode, and view-only access for members without edit permission. Every stroke leaves your device as ciphertext Cloak cannot render.

FORUMS

Long conversations, organized.

Forum channels hold long-form posts with threaded replies, so announcements, guides, and big discussions stay findable instead of scrolling away. Mentions and notifications work exactly like everywhere else.

CALENDAR

Shared calendars, sealed.

Plan inside your servers with recurring events, RSVPs, and reminders. My Calendar rolls every server’s schedule into a single view, and event details stay encrypted end to end.

Moderation & community tools

Run a real community.

Big communities need more than good intentions. Cloak ships the tools to keep yours healthy, and every one of them works without anyone reading your messages.

AUTOMOD

AutoMod that never reads a message.

Rules watch behavior, not content: message bursts, mention storms, attachment floods, embed spam, and poll spam. Set a threshold and a window, choose alert or block, exempt trusted roles, and review every incident in a queue. It works entirely on rate signals, so moderation never needs a peek inside your encryption.

TICKETS

A help desk built into your server.

Members open a private ticket from a menu of topics you define. Staff see every open ticket in one queue, answer in a dedicated channel, and close it out when resolved. Ticket messages ride the same encryption as everything else.

POLLS

Decide things, honestly.

Native polls with multiple choice, time windows, and hidden-until-close results. What a poll says is encrypted end to end; the server only sees the structure it needs to tally votes and genuinely enforce anonymous voting.

Encrypted file vault

Your files, your rules

Every private file you share lives in your encrypted vault. Browse, re-share, revoke future access, or delete, all from one place. Public CDN uploads follow a separate path outside the vault.

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.

  • AES-256-GCM encrypted client-side
  • Stored in private bucket (ACL: private)
  • File keys encrypted with your recovery secret
  • Granular sharing: users or servers
  • Managed from your encrypted vault

Public Upload

PUBLIC, NOT E2EE

Files are uploaded as-is to a public CDN and embedded as direct links. Intended for shareable media like memes and reels. Anyone with the link can access the file, even when the link is posted in an encrypted chat. 10 MB limit on Free, up to 100 MB on Pro.

  • HTTPS delivery, without end-to-end encryption
  • Embedded as direct links in chat
  • Per-file limit: 10 MB Free, 20 MB Basic, 100 MB Pro
  • Supports spoiler & NSFW tags
  • Does not count against vault storage

How the vault protects your files

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

Client-Side Encryption

Private files are encrypted with AES-256-GCM on your device before HTTPS upload. The file service stores ciphertext and encrypted file keys.

Granular Permissions

Share encrypted file keys with specific users or entire servers. Revoke future access without re-uploading. This does not erase copies or keys recipients already saved.

Encrypted File Keys

File keys are encrypted using your separate recovery secret before server storage. Authorized recipients receive encrypted key material to open shared files locally.

Full lifecycle control

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