Privacy Policy

Last updated: February 2026

This privacy policy describes how ProChain (“we”, “us”, “our”) collects, uses, and protects your personal information when you use the ProChain desktop plugin and the Plugin Radar website.

1. Information We Collect

Account Information

  • Email address — used for authentication and account recovery
  • Username — displayed publicly on shared chains, comments, and your profile
  • Password — stored as a PBKDF2 hash; we never store or have access to your plaintext password

Profile Information (Optional)

  • Contact information (phone number, Instagram handle) — used only for friend lookup
  • Display name

Plugin Data

When you use the plugin scanner, we collect a list of installed audio plugins (names, manufacturers, formats) to enable plugin compatibility checking and cloud chain features. This data is synced to the cloud only if you are logged in and have completed the onboarding scan.

Chain Data

When you save chains to the cloud, we store chain name, description, structure (plugin order, group configuration), plugin preset data, and associated metadata.

Social Activity

  • Star ratings, comments, follow/unfollow actions
  • Friend requests and friendships
  • Chain forks

Usage Data

We currently do not collect analytics, telemetry, or usage tracking data. This may change in future versions, and this policy will be updated accordingly.

2. How We Use Your Information

  • Authenticate you and maintain your session
  • Display your username on shared chains, comments, and profiles
  • Enable plugin compatibility checking (matching your plugins against community chains)
  • Deliver chains shared with you by friends
  • Display ratings, comments, and social interactions on community chains
  • Enable friend lookup by username, email, phone, or Instagram handle

We do not sell your data to third parties.

3. Data Storage

All user data is stored in a Convex cloud database (convex.dev). Convex provides encrypted data at rest and in transit, hosted in the United States, with automatic backups. For more information, see convex.dev.

4. Session Management

  • Session tokens are stored in your browser's localStorage and expire after 7 days
  • Tokens are opaque (not JWTs) and cannot be decoded by third parties
  • You can log out at any time, which invalidates your session token

5. Third-Party Services

  • Legal requirements: we may disclose data if required by law

7. Data Retention and Deletion

Your data is retained as long as your account is active. You can request deletion by contacting us (see Section 10). Upon deletion we will remove your profile, saved chains, comments, ratings, friend connections, and synced plugin data. Backups may be retained for up to 30 days.

8. Children's Privacy
