MassPredict.ai is a prediction market aggregation and intelligence platform operated by MassPredict LLC, based in Oakland, California. We are the parent company of SwiPredict.ai. This policy explains how we handle your data.
What we do NOT collect: We do not collect biometric identifiers (fingerprints, facial recognition, voiceprints), geolocation data, audio or video recordings, government-issued identification numbers, or phone numbers. We do not use persistent identifiers to track users across third-party sites for advertising purposes. We do not access, store, or track your activity or account on external prediction market platforms.
MassPredict aggregates public market data from third-party prediction platforms including Polymarket, Kalshi, Manifold, PredictIt, Limitless, ForecastEx, Gemini, and Futuur. We also source prediction data from SwiPredict.ai, our sister platform — not an independent third party. This aggregated data is publicly available market information and is not linked to any individual's account on those platforms.
Data is stored on Supabase (AWS infrastructure, US-based). Serverless functions hosted on Netlify. Payments via Stripe. Authentication via Supabase Auth and Google OAuth. AI features are powered by the Anthropic Claude API — your Raven Aⁱ queries (search text, questions) are sent to Anthropic's API for processing. Your personal identity (name, email) is not included with these queries. See Anthropic's privacy policy for details. If you are in the EEA or UK, data is transferred to the US under Standard Contractual Clauses.
Raven Aⁱ analysis, market summaries, and intelligence features are AI-generated using Anthropic's Claude API. AI output may be inaccurate or incomplete. Do not make financial decisions based on AI-generated content. This is for informational and entertainment purposes only.
SP (SwiPredict Points) used in The Trade simulation have no monetary value, cannot be withdrawn, and do not represent real financial positions. Simulated trading on MassPredict is for entertainment and educational purposes only.
We do not sell your personal information. We do not share your data for targeted advertising. We share data only with the following service providers, solely to operate the platform:
We may also share data when required by law, to protect our legal rights, or to prevent fraud.
We do not share personal information with third parties for their own marketing purposes. We do not use third-party advertising cookies or tracking pixels for targeted advertising.
To exercise these rights, contact contact@masspredict.ai. We will respond within 30 days.
We retain your data only as long as reasonably necessary for the purposes described in this policy:
We do not retain personal data indefinitely. If you delete your account, we will delete your personal data within 30 days, except where required by law or for legitimate fraud prevention.
MassPredict is not directed at children. We require users to be at least 18 years old to access prediction market intelligence and simulated trading features. Our App Store listing carries a 13+ age rating.
We do not knowingly collect, use, or disclose personal information from children under 13. We do not engage in targeted advertising directed at children. We do not collect biometric identifiers, geolocation data, audio recordings, or government-issued identifiers from any users.

We comply with the Children's Online Privacy Protection Act (COPPA) and the FTC's amended COPPA Rule effective April 22, 2026.
EEA/UK users have rights under GDPR including portability, erasure, and the right to complain to your local DPA. Lawful basis: contract performance (subscription), legitimate interests (platform operation), consent (optional features).
California residents have the right to know what data we collect, request deletion, and opt out of data sales. We do not sell personal data. Contact contact@masspredict.ai to exercise your rights.
We use essential cookies for authentication (Supabase session). No advertising cookies. We also use browser localStorage for preferences and session state. Clearing cookies will log you out.
