1. What We Collect

When you sign in with X (Twitter), we receive and store:

  • Your X user ID, username (@handle), and profile picture URL
  • A display name (which you can change in your dashboard)

When you use the site, we also store:

  • Tweet URLs and text excerpts you submit for point verification
  • Memes you upload (images, metadata, moderation status)
  • Solana wallet address, if you choose to provide one
  • Drawings created in the 3D gallery

We do not collect your email address, password, browsing history, IP address logs, or any financial data.

2. How We Use Your Data

  • Authentication — to identify you across sessions via a secure JWT token
  • Gamification — to track your MichiPoints, streaks, and activity
  • Tweet verification — to confirm tweet ownership and content via the public FxTwitter API

We use a session cookie for authentication (JWT-based, expires after 7 days). We also use localStorage for theme preference and gallery settings. We do not use any third-party tracking or analytics cookies.
