Private messaging app without a phone number

A private messaging app that runs in your browser on any phone, laptop or computer. Sign up with just an email address and share a link - people you invite join straight from their browser with no app and no account. Encrypted messages, voice and video calls that delete on your timer, with no AI and no location tracking.

Free account, no phone number. Enter your email → enter the code we email you → share your first chat link. (It's browser chat, not SMS.)

  • Free, no phone number
  • Any phone or computer
  • No account for guests
  • No built-in AI or tracking

Start a private chat in three steps.

Step 1: Create
Name your chat and choose when it deletes: a set date, 24 hours, 3 days, 1 week, or 72 hours after the last message.
Step 2: Share
Send the link to anyone. They open it in their browser and join as a guest. No app, no account.
Step 3: Talk, then it's gone
When the timer ends, the chat and its messages are permanently deleted. Want it gone sooner? Delete it and revoke the link.

Your conversations, your business.

Most encrypted apps still keep a permanent account, contact graph and server record tied to your phone number - and many now build AI directly into your chat screen. SyfChat is built to leave nothing behind.

Whether you're a business owner talking through a sensitive deal, a professional discussing confidential details, or someone who simply values private conversations, SyfChat is secure, reliable and easy to use.

Everything a private conversation needs

No phone number
Sign up with an email. Your number never comes into it.
Guests join by link
The people you invite don't need an account or the app.
Chats delete themselves
Pick a time. When it's up, the chat and its messages are gone.
End-to-end encrypted
Messages are encrypted before they leave your device.
Voice and video calls
Call from the same chat, on a phone or a computer.
Nothing to install
Runs in any modern browser. Add it to your Home Screen if you like.
No built-in AI
No AI bots in your chat list, no writing suggestions, and no AI reading, summarising or training on your conversations. Nothing to switch off.
No location tracking
SyfChat never asks for device location permissions or tracks where you are. No GPS collection, no "nearby" tracking, and no contact-book uploads.

Phone Booths: A disposable server for every chat

Encryption protects what you say. Disposable servers leave no record of who you talk to, or when.

Long-lived messaging apps store your account, contact connections and activity on permanent infrastructure - creating a lasting attack surface if a phone or account is ever compromised.

SyfChat works like a private phone booth: when you create a chat, we spin up a dedicated, temporary message server just for that conversation. Every booth uses multilayer end-to-end encryption. When your timer expires or you delete the chat, the disposable server and everything inside it are permanently destroyed.

Chat securely, anywhere, without the hassle

No phone number. No downloads. No app store. Open SyfChat in your browser on any device, or add it to your Home Screen to launch it like an app. Your team stays connected and your privacy stays protected.
