Privacy Policy
This Privacy Policy explains what information the free online game Machine Party (the “Game”, at machine-party.com) collects when you play, how that information is used, and the choices you have. Machine Party is a browser-based, instant-play party game — you do not need to create an account, and we never ask for your real name, email address or payment details in order to play.
Who we are
Machine Party is made and operated by SunMonkey Studio. If you have any question about this policy or your data, contact us at [email protected], or see our Contact page.
Information we store on your device
So you can keep your settings and progress, the Game saves data locally in your browser (using local storage) or, in the mobile app, in the app’s own storage. This data stays on your device and includes:
- Your chosen display name, avatar colour and language.
- Game progress and session stats: matches played, scores and per-mini-game results.
- Audio, graphics and control settings.
- Whether you dismissed the “install the app” banner, and how much of the daily web-play allowance you have used on mobile browsers.
You can clear this data at any time by clearing your browser’s site data for machine-party.com, or by uninstalling the app. Clearing it resets your local progress and settings.
Information sent to our servers
Machine Party is an online multiplayer game. Our game servers run on Cloudflare. When you play online, the following is processed:
- Multiplayer gameplay — your display name and in-match state (position, pose, actions, round results) are shared in real time with the other players in your room so the match can work. Match state is not kept after the room closes.
- Optional saved identity — if you choose to reserve a display name with a PIN, our server stores the name together with a salted PBKDF2 hash of the PIN and issues a signed token that your device keeps. We never store your PIN in plain text.
- Error reports — when the Game hits an unexpected error, it may send a technical error report (error message, screen and game version) so we can fix bugs.
- Technical data — like any website, our servers automatically receive your device’s IP address and standard request information in order to deliver the Game and keep it secure.
Advertising
The website itself does not run advertising banners inside the game canvas. The optional Android and iOS apps may show ads, including rewarded ads you choose to watch and occasional interstitial ads. Where ads are shown, third-party ad providers such as Google may use device identifiers to serve and measure ads and — where permitted — to show personalised ads.
You can control how Google personalises ads to you at myadcenter.google.com, and read how Google uses data from its partners at policies.google.com/technologies/partner-sites. In some regions you can also opt out of personalised advertising at optout.aboutads.info or youronlinechoices.eu.
Cookies and similar technologies
The Game uses local storage rather than tracking cookies for its own features. Our infrastructure and advertising partners (Cloudflare, and Google in the mobile apps) may set cookies or use similar technologies as described above. You can block or delete cookies in your browser settings; doing so will not stop you from playing.
Third-party services
- Cloudflare — website hosting, game servers and security (privacy policy).
- Google Play and the Apple App Store — if you install the optional mobile app.
- Google — advertising and measurement inside the optional mobile app.
These services process data under their own privacy policies, which we encourage you to review.
Children’s privacy
Machine Party is a family-friendly game, but it is not directed to children under 13 (or the minimum age required in your country). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it. Where required, advertising shown to users we believe may be children is limited to non-personalised ads.
Your rights and choices
Depending on where you live (for example under the EU/UK GDPR or the California CCPA/CPRA), you may have the right to access, correct or delete your personal data, and to object to certain processing such as personalised advertising. Because the Game does not require an account, most of your data lives on your own device and you can clear it yourself at any time. For any request about data held on our servers, such as a reserved display name, contact us at [email protected].
Data retention & security
Local data remains until you clear it. Server-side data is kept only as long as needed for the features described above. We use reasonable technical measures — including Cloudflare’s security infrastructure, salted password hashing and signed tokens — to protect data, though no method of transmission or storage is 100% secure.
Changes to this policy
We may update this Privacy Policy from time to time. When we do, we will change the “Last updated” date above. Significant changes will be reflected on this page.
