Once dIM is installed you never have to access the internet again to send and receive messages. Stay in airplane mode as long as you would like and chat away.
How It Works
dIM uses Bluetooth to maintain a connection to other nearby users of dIM. When you send a message to your friend it is sent trough the Bluetooth connection of other people!
The range of Bluetooth Low Energy is 100 meters or 330 feet. If your friend is further away, the messsage is sent trough other dIM users connection if there are any. Otherwise the message is delivered next time a connection is made.
Add New Contacts
Open dIM on your phone and navigate to the QR code screen. Let your friends scan your QR code, then scan theirs. This enables you to send each other messages trough the dIM network.
dIM is decentralized and all phones play an equal part of keeping the network running. Therefore your phone works as a server and a client at the same time. Another benefit of this is that dIM cannot be shut down or turned off.
No Data Collection
Your data belongs to you. As such no userdata is collected, no connections are made to any servers and no logs are created. The content of your messages are encrypted for only you and your contact to see.
