About End-to-End Encrypted Chat Sync

End-to-end encrypted chat sync allows you to access your Arattai chats securely across multiple devices without compromising privacy, security, or control.
Your messages remain private at all times and are readable only by you and the people you chat with, even when syncing across devices.

What is E2EE Chat Sync  

E2EE chat sync securely syncs recent messages between your primary device and companion devices while maintaining end-to-end encryption.
This ensures:
  • Your chats stay private.
  • Messages are never stored or read by Arattai.
  • You can continue conversations across devices smoothly.

What gets Synced  ?
All your recent end-to-end encrypted conversations and media files are synced to your companion devices. 

How Chat Sync Works  

Arattai uses a primary device model to maintain security while enabling multi-device access.
  • Your primary device acts as the trusted source for your account.
  • When you link a companion device, the primary device securely shares a copy of recent encrypted messages.
  • Each device gets its own encrypted session keys.
  • Messages sent from any device are end-to-end encrypted independently. 

How is it Secure

Seamless chat sync reinforces encryption:
  • Messages are encrypted before leaving your device.
  • Encryption keys are never stored on Arattai servers.
  • Each device has its own secure session.
