About this app

DoU is a messaging app designed with a strong focus on user privacy.
Unlike traditional messaging apps, DoU is not based on contacts but on an invitation-based system, allowing only invited users to communicate within chat rooms.
Without unnecessary connections, DoU provides a simple and trustworthy privacy messenger where you can safely communicate with the people who matter.
If the owner deletes the data, it will be removed from the server, and no third parties, including DoU, will have access to it.

■ Features of DoU
1. Place
Create a conversation space called a Place, invite friends you want to chat with, and start private conversations once they accept the invitation.
2. Contact-based Invitations
You can easily invite friends by syncing your contacts.
3. Focused Group Chats
DoU supports group chats with up to 100 participants, enabling more focused conversations and active participation.
4. Chat with Myself
Use the Chat with Myself feature as a personal memo space for notes, to-do lists, and quick ideas.
5. Quick Search
Easily find chat rooms or Places by searching their names.
