# Flyby A privacy focused conversation app # What makes Flyby different The market around messaging apps is getting pretty dense nowadays, so why should you choose to use flyby? Great question! Flyby's main focus is to provide you with as much privacy as possible. It **will not** track you, it **will not** spy on you, and it **will not** hide anything in hard to read or lengthy documents. # App Features ## Anonymous login There is no need to log into the app. When you download the app a unique id is generated and stored on your device. This id is used to connect you with others using this app. ## Connections ### Anonymous Connections To connect with someone else you must find a way to scan their QR code. Once you connect, you can update their display name to be anything you want. This is only for you and will not be shared with them in any way. ### Severing Connections Once you're done communicating with someone you can easily sever the connection FOR-EV-VER. The only way to reconnect is to rescan your QR code. Severing a connection is permanent! Make sure to only do this when you never want to talk to them again. ## Use Cases ### School Have you ever been assigned to a group project where you're supposed to communicate to one another but don't know them well enough to trust them with your phone number? Connect with your group members with Flyby and sever the connection after the project is complete. ### Dating Dating is hard. It's commonplace to start dating through a website or app and at some point you want to connect with one another outside your dating software. The unknown of a new connection leads people to have alias phone numbers they give out in case your date Scooby-Doo unmasks themselves to be someone you no longer want to talk to. Not anymore! Just connect with Flyby and sever the connection at any time. ## Networking Cocktail parties, galas, weddings, business events, meetups, etc. all have the same problem; connecting. The whole purpose of going to a network event is to be able to communicate with them once it's over. Business cards are outdated, get lost, need to be transcribed into software programs, etc. and other non- business events have you connecting on Facebook, Twitter, LinkedIn, email, or giving out your phone number. Now you can have one location for all your acquaintances that could one day turn into friends, business partners, lovers, associates, bosses, employees, or any other type of connection without the need to electronically distance them up front.

Anonymity is the integral aspect the UUP technology is built on. A group of servers, which do not have access to the whereabouts of the person that connects, form a network at the lower level. Each client is provided with a public key as well as a private key, both of which are not sent to the server. This way, the identity of the user is protected. The hash algorithms derived from the client's device are irreversible making it impossible to trace the public key corresponding to the communication channels open on the server. There are two libraries at the device level. One deals with the transmission protocol with the server while the other deals with a high performing protocol that works at the byte level in the binary to extract the maximum potential of the hardware without weighing down the machine. From simple texts to large video broadcasting, the expandable "point to multipoint" protocol can be used for the massive transmission of encrypted data. The intrinsic speed of the server makes large file transmissions possible. Unlike competing applications, the under-development protocol of UUP guarantees a high level of security and confidentiality through a trustless system and open-source data encryption. Instead of using the notification centers of Google, Apple, or Microsoft, the system acts as a notification center so that nobody, including the system, can make a network of correlation between individuals who use the infrastructure.
