Privacy policy

Short version: the site does not ask for an account or personal details, and the quiz and calculators run in your browser.

Last updated 2 Oct 2026. This is a plain-language policy for a new site and has not been reviewed by a lawyer.

What we collect

Cookies, local storage and your choices

Today the site sets no cookies, runs no analytics and shows no adverts. When you first visit, a banner asks for your choices. "Reject all" and "Accept all" are equally easy, nothing optional is switched on for you, and you can change your mind at any time with the "Cookie settings" button at the bottom of every page.

What this site stores and why
CategoryWhat it isStatus
NecessaryItems kept in your browser's local storage (not cookies) so features work: phv.theme (light or dark), phv.quiz.v1 (practice progress), phv.checklist.v1, phv.planner.v1, phv.breakeven.v1, phv.cpm.v1, phv.taxcalc.v1, phv.runcost.v1, phv.zones.v1, phv.reminders.v1 (calculator figures and reminder dates), and phv.consent.v1 (your choice on this banner, with a version number and the date). They never leave your device and we cannot see them.Always on. These exist only because you used the feature or made a choice.
AnalyticsAnonymous visit counts, if we switch them on. If we do, we plan to use Cloudflare Web Analytics, which says it does not use cookies or track people across sites.Not in use. If it is ever added, it loads only after you accept it.
AdvertisingAdvert serving and measurement.Not in use. There are no ads on this site.

We treat the necessary items as strictly necessary, so they do not need your consent under UK rules on cookies and similar technologies (PECR). You can delete them at any time from your browser settings or with the "Clear my figures" and reset buttons on each page. If we add analytics, advertising or affiliate tracking we will update this page first and ask you before any of it loads.

Not legal advice. This page describes what the site does today in plain English. It has not been reviewed by a lawyer and is not a certified consent management platform.
