Manifold Privacy Policy

Last Updated: May 19th, 2025

1. Introduction​

Manifold Markets, Inc ("Manifold" or "we", "our", or "us") is a social media platform that lets people discuss the future and trade on play‑money prediction markets. Because we ask users to share ideas, forecasts, and data, protecting your privacy is core to our mission. This Privacy Policy explains what information we collect, how we use it, the choices you have, and the rights you can exercise.

By using Manifold—whether through our website, mobile apps, or any other services we provide (collectively, the "Services")—you agree to the terms of this Privacy Policy. If you do not agree, please do not use our Services.

2. Scope​

This Privacy Policy applies to personal information processed in connection with the Services. It does not apply to third‑party websites or services that we do not control, even if they link to, or are accessible from, Manifold.

3. Information We Collect​

3.1 Information You Provide to Us​

  • Account details – display name, username, email address, password, and, if you choose, a profile picture or avatar.
  • Content – posts, comments, predictions, market questions, signals, messages, and any other content you upload or create.
  • Play‑money balances & transactions – the virtual currency ("Manifold$"), trade orders, positions, and settlement outcomes.
  • Communication with us – requests, feedback, survey responses, and any correspondence with customer support.

3.2 Information We Collect Automatically​

  • Usage & log data – time spent, markets visited, search queries, and interactions with content or ads.
  • Device & connection data – IP address, browser type, operating system, device identifiers, and crash reports.
  • Cookies & similar tech – small files or SDK data used to recognize you and to improve and secure the Services (see Section 8).

3.3 Information from Third Parties​

We may receive information about you from:

  • Social sign‑in providers (if you link or create your account using an external service);
  • Analytics & advertising partners that help us understand usage or measure performance.

4. How We Use Information​

We process your information to:

  1. Provide and maintain the Services – create accounts, display markets, execute trades, process play‑money settlements.
  2. Personalize your experience – recommend markets, forecasts, and people to follow.
  3. Enable social features – show your public username, predictions, and comments to other users.
  4. Research & improve – analyze behavior, test new features, and build aggregate statistics (e.g., market accuracy).
  5. Communicate with you – send transactional notices, security alerts, and, with your consent, newsletters or updates.
  6. Ensure safety & integrity – detect and prevent fraud, spam, abusive content, and violations of our Terms.
  7. Comply with legal obligations – respond to lawful requests and enforce our agreements.

If you are in the European Economic Area or United Kingdom, we process your personal data on one or more of the following bases:

  • Contract – as necessary to provide the Services you request (Article 6(1)(b) GDPR).
  • Legitimate interests – to keep our Services safe, improve them, and grow our business, provided those interests are not overridden by your rights (Article 6(1)(f)).
  • Consent – for optional uses such as marketing emails or certain cookies (Article 6(1)(a)). You can withdraw consent at any time.
  • Legal obligation – where processing is necessary to comply with applicable law (Article 6(1)(c)).

6. How We Share Information​

We may share information:

  • Publicly – your username, avatar, predictions, market comments, and trades are visible to anyone unless you use a feature we label as private (e.g., direct messages).
  • Service providers & contractors – companies that host data, send emails, provide analytics or security, and help us operate (bound by confidentiality and data‑protection obligations).
  • Advertising & marketing partners – only if we decide to show ads; partners will not receive your private messages or password.
  • Compliance & safety – to comply with laws, respond to legal process, protect our users, or defend our rights.
  • Business transfers – in connection with a merger, acquisition, bankruptcy, or sale of assets; we will notify you of changes.

We never sell your personal information for money.

7. Your Choices & Rights​

  • Access & portability – request a copy of your data.
  • Correction – update or correct inaccurate information.
  • Deletion – delete your account or ask us to erase certain data.
  • Limit or object – restrict processing under certain circumstances.
  • Withdraw consent – opt out of marketing emails or specific cookies.
  • Do Not Track – we do not respond to browser DNT signals at this time.

8. Cookies & Similar Technologies​

We use cookies, local storage, and mobile SDKs to:

  • Keep you logged in;
  • Remember preferences;
  • Measure site performance;
  • Fight fraud and abuse.

You can control cookies through your browser settings and mobile OS permissions; disabling certain cookies may limit functionality.

9. Data Retention​

We keep your personal data only as long as necessary for the purposes described in this Policy, unless a longer retention is required by law. After account deletion, we typically erase or anonymize data within 30 days, except backups and logs retained for security and compliance.

10. Security​

We implement administrative, technical, and physical safeguards to protect your information, including encryption in transit, access controls, and regular security audits. No system is 100% secure; we encourage you to use strong passwords and enable two‑factor authentication.

11. International Data Transfers​

Manifold is headquartered in the United States. When you use our Services, your information may be processed in, and transferred to, countries outside of your own that may not offer the same level of data protection. We rely on Standard Contractual Clauses or other legal mechanisms to safeguard EU/UK data transfers.

12. Children’s Privacy​

Manifold is not directed to children under 13 (or the minimum age required by local law). We do not knowingly collect personal information from children. If we learn a child has provided personal data, we will delete it.

13. Changes to This Policy​

We may update this Privacy Policy from time to time. If changes are material, we will provide prominent notice (e.g., via email or an in‑app banner) and, where required, obtain your consent.

The "Last Updated" date at the top indicates the effective date.
