⚠️ ⚠️ ⚠️ Please note: This project is no longer officially maintained. In an attempt to focus our maintenance efforts, we have decided to stop the maintenance of some projects, including this one. This means that there will be no further feature updates or bugfixes planned for this app (exceptions only in cases of severe security or privacy issues). Consequently, the app has also been removed from the stores. If someone is interested in taking over the maintenance of this app, please do not hesitate to contact us: [email protected]
Privacy Friendly Werewolf is an open source Android implementation of the Werewolf card game. You can play it with your friends inside a distributed network so that everyone can use its own phone without the need of a game master. The is build to respect your privacy by only demanding as less permissions as possible and not including any tracking algorithms.
Nowadays there are many apps that require many or all permissions available in Android in order to be installed. However these apps do not always need all of the permissions they ask for. With this project we want to offer an app where the user can be sure that private information such as contacts, location, identity etc., are not being used by the application. This app belongs to the group of Privacy Friendly Apps developed by the SECUSO Group at Karlsruher Institute for Technology (KIT).
For further development we recommend Android Studio (version 2.3.1 or higher).

Each participant needs to have Wifi activated, and keep it activated throughout the whole game. When starting a new game (host-player) or respectively connecting to a game (client-player), the player needs to state an in-game name and follow the given instructions. If something goes wrong, there should be a notification telling what went wrong and a suggestion what should be adjusted. After the notification the player is usually directed to the main menu, where he can apply the adjustments and try to start/connect to a game again.
One of the players needs to act as the game host (although he participates in the game as everyone else). The host creates a lobby, by navigating to the main menu (or through the Navigation Drawer) and press "New Game". He also needs to have Wifi activated, or else he will get shown a notification to do so. If done so, his socket address is shown on the screen, which he now can tell to each other player who wants to participate. From now on the Host just waits till everyone is connected to the Lobby (shown as List of Players connected), and then start the game by pressing the "Start"-Button.
Each other player (aside from the host) acts as game clients (although in-game they have the same rights as the host - except for invoking a new round). When the host set up the lobby, and told his socket address to each participant, the client can connect to the lobby by entering the given socket address into the "ip-address" field, and pressing the "Connect"-Button. After a short while, the client gets notified if the connection was successfully established or not. He now just has to wait till the host starts the game and then follow the in-game instructions (same as for the host).
Due to the complexity of network communications in the game, be advised that repeated (and intentional ;)) false inputs, e.g. when trying to connect to a non-existent host, that becomes existent short after, may in some cases lead to unexpected results. So in case of doubt (like for example game says you are connected, but the host does not see you in his list), just go to the main menu and connect to again. Also note that this should not happen in normal cases, but even so, now you know what to do. Another thing: For the clients it is expected to stay in the game as long as the host does. Only the host may end the game (by pressing the X-Button in-game or pressing the hardware back-button).
