What we store on your device
| Name | What it does | How long |
|---|---|---|
| bd-last-check | Remembers the last site you checked, so you can see its report again. Only set if you run a check. | Until you clear it |
| bd-scan | Keeps the result of the check you just ran, so a reload or a trip to another page finds it again. It stays in this tab. Only set if you run a check. | Until you close the tab |
| bd-check-who | Remembers the email, the name and the email box choice you gave for the site check, so a second check does not ask again. Only set if you run a check. | Until you clear it |
| bd-done | Remembers the problems you tick as done on a site check report, one list for each site. Only set if you tick one. | Until you clear it |
| bd-check-pass | A signed cookie that shows the site check you have given an email. It does not hold your email. Only set if you run a check. | 30 days |
| bd-no-count | Remembers that you asked us not to count your visits. Only set if you press the button under Visitor counting. | Until you clear it |
| bd-consent | Remembers your answers on our banner, with a random receipt number, so it does not ask again. | Until you clear it |
| Google Analytics (_ga, _ga_*) | Two cookies from Google: _ga, and one named _ga_ with our code after it. They show us how visitors move through the site, with Google signals and advertising features off. Only set if you press Accept. | 60 days after your last visit, or until you press Reject |
| bd-offer-closed | Remembers the day you closed our 20% move offer, or got a code from it, so the offer does not open again. It holds that date and nothing else, and it is never sent to us. The site works without it, so it is not strictly necessary. It needs no yes from you, because it only remembers your own choice about what the page shows. Only set if you close the offer or sign up. | 30 days, then cleared the next time you open a page that can show the offer |
| Sign-in (Firebase) | Keeps you signed in to your account. Only set if you sign in. | Until you sign out |
| bd-theme | Remembers whether you chose the light or the dark look with the switch in the header. Only set if you use the switch. | Until you clear it |
| Bot check (Vercel BotID) | A security check that runs when you use the site check, the brief, the brief assistant, the founder’s intake or the move code sign-up, to tell a person from a bot and stop misuse. It may keep a short-lived token in your browser for that. | Set by Vercel, short-lived |
| Stripe | Set on Stripe’s own payment page to stop card fraud. Only if you pay online. | Set by Stripe |
None of these follow you around the web, and none are used for advertising.
The button clears what your browser keeps for the site check, apart from bd-check-pass. Our pages cannot read or clear that one. It ends after 30 days, or you can delete it in your browser’s settings.
Closed our 20% move offer and want to see it again? This clears bd-offer-closed, the one note it keeps. The site uses it for 30 days at most, and it only remembers your own choice.
Your choice
Anything marked as waiting for your yes runs only after you press Accept on our banner, and each has its own yes. Reject is as easy, and carrying on browsing is not a yes. You can change your mind at any time, with one press, here or from the foot of the site’s main pages.
Visitor counting
We count visits ourselves, to learn which pages are read and improve the site. When you start using a page, your browser tells us which page it is. For the first page of a visit it also says the kind of site that sent you, and the short code if you came from one of our letters, leaflets or posts. We keep only the totals for each day, one running total for each short code, and no record of any one visitor. It uses no cookie, and we do not read what kind of phone or computer you use. Your internet address is held briefly in memory for rate limiting, never written to storage.
You can stop it for this browser with one press, here or from the foot of the site’s main pages. Short links are covered too. Your browser then keeps one line, bd-no-count, to remember your choice.
