Right-click → View Source. We have no backend.

Everything you enter into the calculator stays in your browser. There's no server taking your numbers, no email signup, no cookie that tracks who you are. The page is static HTML + JavaScript served from Vercel's CDN; the JavaScript runs entirely on your device.

What we collect

• Anonymous page viewsvia Vercel Analytics. Cookieless. Aggregated. We see "103 visits to the homepage today", not who you are.
• Anonymous performance metrics via Vercel Speed Insights — page load times, layout shifts. Cookieless.

What we don't collect

• Your name, email, phone, or any contact info — there's no form for it.
• Your income, family details, or calculator inputs — these never leave your browser.
• Tracking cookies. Advertising cookies. Anything you'd see a banner about.

What we don't do

• Sell or share data (we don't have any).
• Send marketing emails (no list).
• Run ads.
• Link to daycare providers, banks, or financial-advisor lead-gen pages.
