Privacy Policy - MassPredict.ai

1. Who We Are

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.

3. Data Sources

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.

4. How We Use Your Data

To manage your subscription and process payments
To track simulated SP trades and display your activity
To send price alerts and watchlist notifications
To improve our aggregation algorithms and AI models
To prevent abuse and maintain platform security
Aggregate, anonymized data may be used for analytics

5. Data Storage & Processors

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.

6. AI & Raven Aⁱ

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.

7. SP Simulated Trading

SP (SwiPredict Points) used in The Trade simulation have no monetary value, cannot be withdrawn, and do not represent real financial positions.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.
