Cookies and similar technologies
This site stores very little on your device and nothing that tracks you across other sites. This page lists everything it can store, what each item is for, how long it lasts, whether it needs your consent, and how to change your choice.
What we store, and why
Nothing is stored for advertising, and no advertising or social network sets anything here. Our fonts and images are served from our own hosting, so a visit makes no request to Google, Meta or any other advertising network. The only party other than us that can set anything is Cloudflare, which serves the site.
| Name | What it does | Type | Lasts | Needs your consent |
|---|---|---|---|---|
| wfConsent | Records whether you accepted or rejected optional storage, so we do not ask again | Local storage, set by this site | We honour it for 12 months, then remove it and ask again. It is also removed the moment you change your choice | No. It exists only to record and honour your choice |
| wfEvents | A short list of the pages you viewed and the buttons you used on this site, sent to our own server so we can see which pages are read and where people get stuck. It contains no name, no email and nothing from any other site | Local storage, set by this site | Until sent, then cleared; our server keeps the batch for 90 days | Yes. Nothing is written unless you have accepted, and the record is deleted if you later reject |
| __cf_bm | Cloudflare's bot-management cookie, set when Cloudflare's protection is active for this site, to tell genuine visitors from automated abuse | Cookie, set by Cloudflare | Up to 30 minutes | No. It is essential to keeping the service you asked for available and secure, which the Regulations exempt |
Pages that let you configure a plan or an estimate keep your choices in the page while you use it and do not store them after you leave.
Your choice
When you first visit, a bar at the foot of the page asks whether you accept the optional storage above. Accept and Reject are the same size and each takes one click; nothing is pre-selected, and if you do nothing, nothing optional is stored. You can change your mind at any time with the button below, which clears your recorded choice and any usage record and asks you again.
How the law applies
The Privacy and Electronic Communications Regulations require your consent before anything is stored on or read from your device, unless it is strictly necessary to provide a service you have asked for, is needed to transmit a communication, or falls within the other narrow exceptions the Regulations allow. Cloudflare's security cookie and the record of your own choice fall within those exceptions. Our usage measurement does not, which is why it is off until you switch it on. Our privacy notice explains what happens to any personal data we hold.
