Your data stays on your machine
Flowgauge runs entirely in your browser. No server receives your Jira data, no account is required, and nothing is stored outside your own device.
What happens when you upload a CSV:
- Every calculation — lead time, throughput, cycle time, WIP, aging, Monte Carlo — runs in JavaScript on your machine. Your Jira data is never transmitted.
- For convenience, the app caches your most recent upload in your browser's own
localStorage so the dashboard auto-restores when you reload the page. This stays on your device. To remove it, use the in-app reset or clear this site's storage in your browser (see "Clearing your data" below). - Saved views ("Snapshots") are written to your browser's own IndexedDB storage. They also stay on your device and are never synced or shared.
- On first load the page fetches four open-source charting and parsing libraries (Chart.js, PapaParse, chartjs-adapter-date-fns, Dexie) from a public CDN (jsDelivr). These are integrity-pinned (SRI) so the browser refuses any tampered file. This is a normal page load — no Jira data is involved.
- The static hosting provider (GitHub/Cloudflare) and the CDN see only standard HTTP request logs: IP address, path, and timestamp. Neither ever receives Jira data.
What the site does not do:
- Set cookies.
- Fingerprint your browser.
- Send analytics events containing your data.
- Require an account or sign-in.
If a cookieless aggregate page-view counter is later enabled, it will count visits only — no individual tracking, no data attached.
Clearing your data
Your uploaded CSV cache and saved Snapshots live in your browser's storage for this site. To remove them: use the in-app reset, or clear site data for flowgauge.app in your browser settings (this wipes both the localStorage cache and the IndexedDB Snapshots). On a shared or public machine, do this before you leave.
As-is disclaimer
Flowgauge is provided as-is, for informational and analytical purposes only.
The calculations follow published Kanban-standard definitions (lead time, cycle time, throughput, Monte Carlo forecasting), but you are responsible for verifying that the outputs make sense for your team's specific workflow before acting on them. Flow metrics are inputs to team conversations, not management targets.
Flowgauge is not affiliated with Atlassian, Kanban University, or any organisation whose tools or methods it may reference. "Jira" is a registered trademark of Atlassian Pty Ltd.
The "Load sample data" option loads a fully synthetic dataset (a fictional team, generated for demonstration purposes). It is not real company data.
