If you find a security issue in Mainframe, please report it privately — don't post it publicly.

• Inside the app: use Report a Problem. It reaches us directly and attaches the details we need.
• Or: kvrnl.io/contact

Tell us what you found, how to reproduce it, and the version you're on. We'll acknowledge your report and keep you posted on the fix.

Only the latest release of Mainframe receives security fixes. The app updates itself, so staying current is automatic.

• Test against KVRNL servers in ways that could disrupt service.
• Access, change, or delete other people's data.
• Publish the issue before we've had a chance to fix it.

Thanks for helping keep KVRNL users safe.
