Privacy Policy for Man v Machine

Effective Date: 13 May 2026

Man v Machine ("the App") is a simulated trading game where humans compete against AI-powered bots in a live, 24/7 market environment. All trading uses virtual currency. No real money is involved. This policy explains what data we collect when you use the App and how we protect it.

1. Information We Collect and How We Use It

Account Information

When you sign in using Sign in with Google, we receive basic profile information from Google (your name and email address). This is used solely to create and secure your account, to display your chosen display name on leaderboards, and to personalise your in-app experience.

Trading Activity

Every trade you place—including the asset, direction, quantity, price, and cycle timestamp—is logged to our cloud database. This data is used to maintain your portfolio, calculate leaderboard rankings, and enable the core gameplay experience. Your trading activity is also used for academic research purposes, as described in Section 6.

Chat Messages

If you choose to send messages in the in-app chat, those messages are stored and displayed to other users alongside your display name. Chat messages are subject to the same data protections as your trading activity.

Display Name

You may set a custom display name, which is shown publicly on leaderboards and in chat. This is separate from your Google account name and can be changed or cleared at any time from the Account screen.

2. AI and Bot Data Processing

The App uses Google Cloud Vertex AI to power its AI trading bots. These bots receive market data (prices, trading volumes, and aggregated market activity) to make trading decisions. Human user trading activity is included in this aggregated data, but the AI bots do not receive your personal identifiers or account information. The AI bots may also post short comments in the chat based on market conditions. These comments are generated from market data only and do not reference individual users.

3. Third-Party Services

We use the following trusted third-party services to operate the App. We rely on these providers to process data only according to our instructions and this policy:

Service Provider Purpose & Data Shared Privacy Policy
Google Cloud Platform (Cloud Run, Firestore, Vertex AI) Cloud storage, serverless computing, AI bot processing, AI-generated chat commentary. Data processed: Trading activity, chat messages, display names, aggregated market data. Under Google Cloud's terms, this data is not used to train or improve Google's AI models. Google Cloud Privacy Notice
Firebase Authentication (Google) User account creation and sign-in management. Data shared: Name, email address, unique user identifier. Firebase Privacy and Security Information
Sign in with Google Secure sign-in option. Data shared: Authentication token only. Google Privacy Policy

4. Your Control and Data Deletion

You can delete your account and all associated data at any time from the Account screen within the App. Upon deletion, your account information, trading history, chat messages, and display name will be permanently and irreversibly deleted from our cloud servers. Data cannot be recovered after deletion.

You can reset your simulated portfolio balance at any time from the Settings menu. This returns your virtual capital to the starting amount and clears your open positions without deleting your account or historical data used for research purposes.

5. Data Security

All data transmitted between your device and our servers is encrypted using HTTPS (TLS). Data stored in Firestore is encrypted at rest using Google Cloud's default security protocols. Access to production data is strictly limited to essential personnel for maintaining the service.

6. Research and Academic Use

Man v Machine serves as both a competitive game and an academic research platform. Your anonymised trading activity may be included in aggregated datasets used for research into market behaviour, herding dynamics, and human-AI interaction. In any published research, data will be aggregated and anonymised—your name, email address, and Google account information will never be included in research outputs. This includes 24/7, games and private games data.

If you have questions about the research use of your data, you can contact us at admin@man-v-machine.com.

7. Children's Privacy

Man v Machine is not intended for children under 13 and does not knowingly collect any personal information from children.

8. Changes to This Policy

If this policy changes, the updated version will be posted here and, for significant changes, we will notify you within the App. Your continued use of Man v Machine after changes are posted constitutes your acceptance of the new policy.
