Please report vulnerabilities privately via GitHub Security Advisories — do not open a public issue for security problems.
You should expect an initial response within a week. As a local-first desktop app, the most sensitive surfaces are the OAuth token store, the Google Sheets connector, and the SQLite database in the user's app-data directory.
Only the latest release receives fixes.
All release artifacts carry SLSA build provenance. Verify any downloaded binary with:
