🔒 100% Local — No Data Uploaded

All calculation data, income records, and tax scenarios are stored locally in your browser via localStorage.

No personal financial data is uploaded to any server. No email or account registration is required to use this site.

What Data Is Stored?

• Tax scenario names and calculation results (stored only if you click "Save Scenario")
• No names, SSNs, or addresses are ever collected
• Data persists in your browser until you clear it or click "Clear All Data"

Third-Party Services

This site uses no analytics, no ad tracking, and no third-party data collection. The only external resource is Chart.js (loaded via cdn.jsdelivr.net) for rendering tax trend charts — no user data is sent to the CDN.

Cookies

We do not use cookies for tracking. The only local storage used is localStorage for saving your tax scenarios (if you choose to save them).

Your Control

You can clear all saved data at any time by clicking "Clear All Data" in the Saved Scenarios tab, or by clearing your browser's localStorage for this site.
