Plain language, no dark patterns

Privacy

The short version: the calculator runs entirely in your browser. The numbers you enter are not sent anywhere, not stored, and not seen by anyone — including us.

What the calculator collects

Nothing. Every figure you type or slide — savings, spending, the withdrawal rate, the reflection answers — is processed locally in your browser and never transmitted to a server. Close the tab and it’s gone. There is no account, no login, and no saved profile, by design.

Analytics

This site may use privacy-respecting, aggregate analytics to understand roughly how many people visit which pages. That data is anonymous and never tied to the values you enter in the calculator. If detailed analytics are ever added, this page will describe them specifically before they go live.

Advertising

The site is intended to carry clearly-labelled display advertising, placed only above the tool and after a complete result. When advertising is active, the ad provider (Google AdSense) may use cookies to serve and measure ads, as is standard for display advertising on the web. You can manage ad personalization through your Google account settings and your browser’s cookie controls. Until advertising is active, the slots are inert placeholders and set no advertising cookies.

What this site will never do

Contact

For any privacy question, the contact route will be listed here. If this policy changes, the change will be described in plain language on this page rather than buried in a longer document.
