Only the latest release receives fixes.

Please don't open a public issue. Report it privately through GitHub security advisories.

Include what you found, how to reproduce it, and its impact. You'll get a reply within a few days, and credit in the release notes if you'd like.

Math Game runs fully offline. It makes no network requests, collects no telemetry, and writes only one file: progress.json in the per-user app-data folder. The areas most worth checking are the parsing of that file and of stages.json, and the integrity of the release packages.
