Cookie policy
Short, because there isn't much. Two cookies keep the site working. Google Analytics only runs if you click Accept. Nothing is used for advertising.
What cookies are
Cookies are small files a website stores in your browser. Some are needed for the site to work. Others, such as analytics cookies, need your permission first under the Privacy and Electronic Communications Regulations (PECR).
Cookies the site needs
These are set without asking, because the site cannot work without them.
| Name | Set by | What it does | How long |
|---|---|---|---|
hedgevolt-session | Hedgevolt | Remembers what you entered in the postcode check while you finish it. | 2 hours |
XSRF-TOKEN | Hedgevolt | A security token that stops other sites submitting our forms as you. | 2 hours |
__cf_bm, cf_clearance | Cloudflare | Set only when needed, to tell people from bots and block attacks. | Up to 30 minutes (__cf_bm); for the security check's lifetime (cf_clearance) |
Analytics cookies, only if you accept
If you click Accept on the cookie banner, Google Analytics (Google Ireland Limited) counts visits and shows which pages help. It never receives your postcode, email or report, and it never runs on report pages. If you click Reject, or never choose, it does not load and sets nothing.
| Name | Set by | What it does | How long |
|---|---|---|---|
_ga | Google Analytics | Tells one visitor from another, so visits are counted once. | 2 years |
_ga_<ID> | Google Analytics | Keeps track of the current visit. | 2 years |
Things that are not cookies
- Your cookie choice is kept in your browser's local storage as
hv-analytics, so the banner does not ask again on every page. It stays until you clear your browser data. - Cloudflare Web Analytics counts page views without cookies and without storing anything on your device. It does not identify you or follow you to other sites.
- Payment happens on Stripe's own checkout page (checkout.stripe.com), which sets its own cookies for fraud prevention under Stripe's cookie policy.
- Our email sign-up sets no cookies.
Changing your mind
Click at the bottom of any page to change your choice. Choosing Reject also deletes the Google Analytics cookies. You can also block or delete cookies in your browser settings; the site still works without analytics cookies.
