What is Chadder?
Chadder is a simple cross-platform private messaging application. We make privacy easy to reach and fun to use. We never see what you send. Say what you want, we can't see it anyway!
Our encryption system locks your message before it's sent through our servers, and then unlocks it only once it reaches its destination.
We allow you to send pictures over our servers, with the same end-to-end encryption as normal messages.
We provide 100% private conversations with your contacts. We never see what anyone says within our app.
QR Code System
We give you many ways to add friends. With a QR Code, you can be sure that it's actually your friend adding you.
Simple Friend Adding
Once you know the nickname of the person you wish to add, search for them using the search function.
Who made this?
Chadder was developed by 7 students from Rochester Institute of Technology. We have worked tirelessly to build an application that is balanced between fun and private. Time and time again we have seen "private" applications with access to your information and we thought it was about time someone changed that.
Since we're college students, we're operating on a very limited budget. In order to bring you the best, we need money to bring on more developers and designers, and to get a better infrastructure to manage as many users as we can.
Why should I care about privacy?
There have been many news articles lately regarding online privacy, many of which claim that "once you put it on the internet, it's there forever." There's also stories like THIS that we aim to prevent.
Why did you build Chadder?
We as a team built Chadder to provide an alternative to all of the public messaging applications out there: Facebook, SnapChat, Twitter, Tumblr, etc. And our goal is to build and maintain a system that will always put the user in control.
How do I add contacts on Chadder?
To add a contact, a couple things have to happen:
1) Make sure you go to settings and make sure you have entered a name to be found with.
2) Check the box next to the field you just filled out.
3) Hit submit.
4) Not required, but recommended: scan the other user's QR Code next time you see them.
This allows people to find you by the criteria you have checked public next to.
What is the goal for Chadder?
Chadder is aiming to be the application that allows normal everyday people to have private communication. We are not claiming to be the perfect security application because there is no such thing.
What is the difference between security and privacy?
The difference between Security and Privacy is simple. You can be secure without being private. It is very hard to be private without first being secure. Think of it like an airport: nobody is going to harm you (the security aspect), but your stuff has just been searched (the privacy aspect).
What type of encryption do you use?
We use ECDH with the SecP256k1 curve (the same form of encryption that Bitcoin uses), combined with AES 256. We also use ECDSA for message signing. Our user key thumbprints use SHA-1.
