Requires the app

Test server

A public server you can connect the app to, without a server of your own. It requires the SacketChatty app on iPhone: the test server cannot be used in any other way.

Get the app for iPhone

Reset every 10 days

Every 10 days the test server is wiped: all accounts, messages and files are deleted, without notice. Do not use it for real conversations or sensitive data.

Public beta on TestFlight

SacketChatty is not on the App Store yet: you can install it now through the public beta on TestFlight, Apple's app for pre-release versions. Install TestFlight on your iPhone, then open the link.

Join the beta

Connect the app

  1. Install the SacketChatty app on your iPhone (iOS 26 or later) and open it.
  2. On the Set Up Server screen, tap Use the Test Server: the connection details are already in the app.
  3. Wait for Tor to reach the server: the first time it can take a minute.
  4. Tap Sign Up and choose a username and a password.

Using it every day

For everyday use you can ask for a personal server, set up and managed by us, with the costs at your charge. Write to sacketchatty@proton.me.
