Privacy policy
This page is maintained by the What EV team and explains what we collect when you use the cost calculator, the EV quiz and our guides. Last updated 2026.
What we collect
You can use every tool on What EV without giving us any personal information. We record anonymous, aggregate answers from the calculator and the quiz — things like annual mileage, driving profile, charging access, budget band and which models matched — so we can improve the tools. These records contain no name, address, IP address or account.
The one piece of personal data we collect is your email address, and only if you choose to type it in on the quiz results page to have your matches sent to you. It is optional.
Why we collect it
Anonymous answers are processed on the basis of our legitimate interest in understanding how the tools are used and keeping our assumptions accurate. An email address, when you give one, is processed on the basis of your consent, solely to send you the results you asked for.
How it is stored
Submissions are stored in an access-controlled database with row-level security enabled. No public or anonymous read access is granted, so stored records — including email addresses — are not reachable from any public endpoint or from the website itself. Data is transmitted over HTTPS only.
Who we share it with
We do not sell your data and we do not share it with advertisers. Our hosting and database providers process it on our behalf as data processors.
Cookies and consent
Strictly necessary cookies keep the site working and your cookie choice remembered; under PECR these do not require consent. We set no advertising cookies and no third-party tracking pixels.
Optional analytics cookies are only ever set after you actively accept them in our cookie banner. Nothing analytics-related loads before that — no scripts, no cookies, no requests. Your choice is stored in a first-party, SameSite=Lax, Secure cookie containing only the categories you agreed to, the date and a policy version; it is never shared. You can change or withdraw consent at any time via Cookie settings in the footer, and we re-ask automatically after six months.
How long we keep it
Anonymous submissions are retained for up to 24 months. Email addresses are kept only for as long as needed to send the results you requested, and are deleted on request.
Your rights
Under UK GDPR you have the right to access, correct, delete or restrict the processing of your personal data, to withdraw consent at any time, and to complain to the Information Commissioner's Office. Because our analytics records are anonymous, these rights apply in practice to any email address you have given us.
Third-party price data
Our pages fetch live UK fuel and electricity prices from public data feeds. These requests are made by our servers, not your browser, so those providers do not receive your details.
