This app is NOT a chat app. This apps main purpose is to demonstrate encrypting and decrypting cloud variable values. The program also locally maintains a short history of prior values of the decrypted cloud variable. Received messages will not display capitalization. There is a 1 in 44,444 chance your message won't be received, everytime you send a message.
Load this in multiple browsers if you don't have other people to test with. I made this within two hours while bored. If you are trying to send unique characters, but they aren't registering. Make a remix and add your characters to the "definitions" list.
