What we collect, what we don’t, and where your numbers actually go.
Last updated 2026-07-23.
The notice, itemised
| Personal data collected | None. Every calculator runs entirely in your browser — your inputs are never sent to a server to be calculated, and we never see your corpus, expenses, or results. |
|---|---|
| Non-personal data collected | Two tool-slug strings and a boolean per “next decision” link click (for example, corpus-target → sip-to-goal, whether numbers were carried across). Aggregate only — no identifier ties two clicks to the same visitor. |
| Purpose | To see which decision paths people actually follow, so the connected journeys can be improved. |
| Retention | 90 days. This data is stored in Cloudflare’s Workers Analytics Engine, whose stated retention period is three months. |
| Sharing / processors | Cloudflare — for hosting, the traversal analytics dataset above, and Cloudflare Web Analytics (page-visit counts). No other processor. |
| Cross-border processing | This site runs on Cloudflare’s global network, which serves and processes requests from whichever edge location is nearest to you — not confined to one country or region. We haven’t configured Cloudflare’s data-localization options, since there’s no personal data collected that would need geographic restriction. |
| Your rights | See your data rights for all six, and how to exercise them. |
| Grievance route | See the grievance officer page for who to contact and the response timeline. |
| Children | This site isn’t directed at children under 18. We don’t knowingly collect data from anyone, of any age, and don’t process data in ways that would require verifiable parental consent. |
| URL parameters | Your numbers travel between tools as URL query parameters — visible in your address bar, saved in your browser history, and included if you copy or share that link. Share deliberately. |
| Last reviewed | 2026-07-23 — updated whenever what the code actually does changes. |
In plain language
Every calculator on this site — including the Retirement Planner’s Monte Carlo simulation and the Retirement Corpus Target Calculator’s stress-tested search — runs entirely in your browser. This is a factual statement about how the code works, not a promise layered on top of it: nothing in this site’s code makes a network request to compute a result.
We use Cloudflare Web Analytics, enabled at the network level (not a script we embed), to count page visits — it’s cookie-less and doesn’t track you across other sites. Separately, the traversal analytics described above logs tool-to-tool clicks in aggregate. See the cookie policyfor why there’s no consent banner.
We don’t use cookies or browser storage of any kind — there is genuinely nothing stored on your device by this site beyond what your browser caches for performance.
