Midnight Mafia is a free party game. It has no accounts and no visitor statistics of its own. This page explains the information the game uses, why, and how ads on the site work.
One phone, passed around
Everything stays on the phone you play on. The names you type, your settings, your scores and a game you saved are kept in the phone's browser storage. They are never sent to us or anyone else.
When nobody has used the game on the phone for 2 hours, it deletes the names, the saved game and the scores. This happens as soon as the game is next on screen or opened. Settings such as timers and the narrator's voice stay. You can also remove everything at any time by clearing this website's data in your browser settings.
Everyone on their own phone
To let phones play together, the game uses Google Firebase, an online database run by Google.
- Your name in the room. The name you type when you create or join a room is saved in the room, so the other players can see it. Use a first name or nickname, not anything private.
- A random player number. Each phone is signed in anonymously and gets a random ID. It is not linked to your email, phone number or any account. It only lets the game keep your role, night picks and votes private.
- The game itself. Roles, night picks and votes are saved in the room while you play. Each player can only see their own secret role.
- How long it is kept. When the host presses "Close this room", the room and everything in it are deleted straight away. Otherwise, once nobody has used a room for 2 hours, it is deleted automatically with every name, role and vote in it. This is checked every 15 minutes.
- Spam protection. Google reCAPTCHA checks that requests come from a real phone using this website. To do this, Google collects information about your device and browser. Google's Privacy Policy and Terms of Service apply.
Your phone also remembers your settings and the last name you used, so you don't have to type it again. After 2 hours without use, it forgets the name and which room it was in.
Other services the game uses
- Netlify hosts this website. Like any web host, it may keep basic visit records, such as your IP address and browser type.
- Google Fonts supplies the game's lettering. Your browser asks Google for the font files.
- Cloudflare (cdnjs) supplies the tool that draws the room's QR code, in the online game.
