Privacy Statement

Last updated: 2026-07-19

We collect nothing

FireMan does not collect, transmit, or store any data about you or the firewall configuration you analyze. There is no account, no login, no analytics, no telemetry, and no cookies.

Your configuration file never leaves your device

When you drop a configuration file into FireMan, it is parsed and analyzed entirely inside your browser tab, using JavaScript that runs locally. The file is never uploaded to any server — not to Microsoft, not to us, not to any third party. You can verify this yourself: open your browser's developer tools to the Network tab before running an audit, and confirm no request completes successfully during the entire process. You may see one blocked (not completed) request to res.cdn.office.net — this is the bundled Microsoft Teams SDK attempting to refresh its own list of trusted Teams domains, which our Content-Security-Policy blocks before it can complete; the SDK immediately falls back to its own identical bundled domain list, and no data of any kind is sent.

Hosting is not the same as data collection

FireMan's static files (this page, the app tab, the manifest) are served from a web host so Microsoft Teams can load them. That is a hosting relationship for delivering code, not a channel through which your configuration data travels — the audit logic executes only in your browser, after the page has already loaded.
