Nothing but the strictly necessary items below is stored until you choose. You can change your mind whenever you like, there is a button at the end of this page, and one in the footer of every page.
1. Strictly necessary
These are set without consent because the site cannot work without them. They carry no marketing or profiling function.
| Name | Purpose | Lasts |
|---|---|---|
b3v_consent | Remembers the choices you made in the cookie banner, so you are not asked again on every page. | 180 days |
__Host-authjs.csrf-token | Protects the staff sign-in form against cross-site request forgery. Only set on the back-office login screen. | Session |
authjs.session-token | Keeps a signed-in staff member signed in. Never set for ordinary visitors. | 30 days |
2. Analytics, only with your consent
Our own analytics are first-party: the data is collected by this site and stored in our own database. If you accept analytics, we store one item in your browser:
| Name | Purpose | Lasts |
|---|---|---|
b3v_sid, b3v_sid_at | A random identifier that groups the pages you view into one visit, so we can tell one person reading five pages from five people reading one. | 30 minutes of inactivity |
We never store your IP address. To count returning visitors we derive a one-way hash from your IP address and browser, combined with a salt that changes every day, which means the hash cannot be used to link your visits across days, by us or by anyone who obtained the data.
If you decline analytics, we still count the page view so we know how busy the site is, but with no session identifier and no visitor hash. The record is an anonymous aggregate that cannot be connected to you or to your other visits.
We also use Ahrefs Web Analytics to see which pages people find and read. It sets no cookies and stores nothing on your device, it does not store your IP address, and it is not used to identify you or follow you to other sites. Because nothing is stored on your device it runs whether or not you accept analytics, and only on our public pages.
3. Marketing, only with your consent
If you accept marketing cookies, and only then, we load third-party tags to measure advertising. These set their own cookies under their own policies:
- Google Analytics / Google Ads (
_ga,_gcl_au), campaign measurement and conversion attribution. - Meta Pixel (
_fbp,_fbc), measures whether an advert led to an enquiry.
No tag is loaded before you consent, and none of these are loaded on the staff back office or the sign-in pages at all.
4. Other browser storage
A few small preferences are kept in local storage rather than cookies. They never leave your device and are not sent to us:
- the currency you chose on the pricing page;
- whether you have dismissed the announcement bar;
- whether the introduction animation has already played in this browsing session;
- campaign parameters from the link you arrived on, held so that if you go on to create an account we can tell which campaign brought you. Stored only if you accept analytics or marketing, and kept for 90 days.
5. Changing your choices
Change your consent at any time using the button below, or the one in the site footer. You can also clear or block cookies in your browser settings; if you do, the strictly necessary items will be recreated as needed and the banner will ask you again.
