Privacy Policy

The calculators save your inputs in your browser’s local storage so they are still there when you come back. A few facts you enter in one calculator (your age, state, salary and take-home pay) are kept so the next calculator can start from them. None of it is sent to our servers. The planner sandbox at /sandbox keeps a copy of plans you change, for up to three sessions, so that signing up later can offer to import one; each copy is deleted 30 days after its last change, and starting over removes it.

To clear all of it, clear this site’s data in your browser settings (often under “Cookies and site data”).

When you use Share, your inputs are written into the link itself. Anyone with the link can see those numbers, so share it only with people you trust. We don’t store shared links.

We use Vercel Analytics and Vercel Speed Insights to count page views and measure how fast pages load. They record the page, referrer, country, device type and browser, without cookies, and never what you type into a calculator. Our host, Vercel, keeps standard server logs (such as IP address and the page requested) for security and troubleshooting.

If you email us, we keep your message and address to reply. That is the only personal information we hold.

• No accounts or sign-in yet, so we hold no profile about you.
• No advertising, ad cookies or cross-site tracking.
• No selling or sharing of personal information.

Because we don’t track you across sites, Do Not Track and Global Privacy Control signals change nothing here today; we will honor them if that ever changes.

Accounts and ads are planned. Before either goes live we will rewrite this policy, show a notice on the site announcing the change, and update the date above.

The site is for adults. We do not knowingly collect information from anyone under 18.
