Privacy Policy

Updated May 10, 2026

We collect minimal information required to run and protect our Minecraft client and launcher. For questions or privacy requests, contact us at privacy@prismclient.net.

What we collect

  • Minecraft JWT token: used only once at login to verify identity and immediately exchanged for a Prism session token. We do not store your Minecraft token.
  • Prism session token: issued by us and kept only for the active session (invalidated on logout or expiry).
  • Social/presence data: username, online status, and which server you are on. Stored only for the duration of the session, plus a single "last online" timestamp after disconnect.
  • IP addresses & connection metadata: used to detect and prevent abuse and investigate incidents.
  • Diagnostics: crash reports and error data. We use Sentry for error monitoring and limit the personal data sent.

How we use data

  • Authentication: exchange your Minecraft JWT once per login for our session token.
  • Social features: power presence, friend lists, and join requests while you are connected.
  • Security: detect and prevent abuse using IPs and logs.
  • Debugging: use Sentry and logs to find crashes and bugs.

Sharing and retention

  • We do not sell personal information.
  • We forward diagnostics to Sentry and may share data with service providers (hosting, storage, security). Providers are contractually limited to use data only for services.
  • Minecraft JWTs are not stored; session tokens and social data are kept only for the active session (we keep a "last online" timestamp after disconnect); IP logs are retained for up to 90 days; Sentry data is retained up to 60 days.

Your rights

You may request deletion by emailing privacy@prismclient.net. We will verify your identity before fulfilling requests.

Other

  • Children: not intended for children under 13.
  • Security: we implement reasonable safeguards but cannot guarantee absolute security.
  • Changes: we may update this policy; the updated date will change when we do.
