Direct answer

The CSV includes deploys/week, failed/week, devs, MTTR, blended FTE cost, annual failures, annual total deploys, CFR %, and annual engineering burn. Generated entirely client-side; no data leaves your browser.

What the file contains

Two columns plus a unit column: metric, value, unit. Header row included for spreadsheet import. UTF-8 encoded. No PII because there is no PII; we never ask for one.

Re-running with new inputs

Change any input and click Download again. Each export is independent; nothing is versioned server-side. If you want to track the same team over time, append timestamp to the filename when saving.
