Cookie notice
Last updated 4 November 2026
Cookies are small files a website saves in your browser. Sites can also save information in your browser’s local or session storage. This notice covers both, and explains what CompaniesBoard stores and why. For everything else about your personal information, see our privacy policy.
On companiesboard.com
This website doesn’t use cookies. We count visits with PostHog in a cookieless mode: it keeps an anonymous ID in memory for the page you’re on and saves nothing to your device, so a visit can’t be linked to you or to your next visit. That’s why there’s no cookie banner here.
The only thing we save is your display preference:
| Name | Type | What it’s for | How long |
|---|---|---|---|
cb:theme | Local storage | Remembers whether you picked light, dark or system mode | Until you clear it |
In the app (app.companiesboard.com)
Essential
These are needed to sign you in and make the app work, so they don’t need your consent.

sb-…-auth-token-code-verifier | Cookie (Supabase) | Protects sign-in with Google while it completes | A few minutes |
cb:return-to | Session storage | Takes you back to the page you were on after signing in | Until you close the tab |
cb:signup-intent | Session storage | Carries the plan and any search you chose on companiesboard.com through sign-up | Until you close the tab |

Analytics
We use PostHog, hosted in the EU, to see how the app is used, such as which pages are visited and which features people use, so we can improve it. Like the website, the app runs PostHog without cookies: it keeps its ID in memory and saves nothing to your device. Once you’re signed in, events are linked to your account (see our privacy policy).
Other services
When you pay for Pro, you’re taken to a checkout page run by Stripe, which sets its own cookies for payments and fraud prevention. If you book a call after a business enquiry, the Cal.com booking widget may set its own cookies. If you sign in with Google, Google’s sign-in page uses its own cookies. Their cookie policies explain these.
How to control them
You can block or delete cookies and site storage in your browser’s settings. If you block the essential cookies, you won’t be able to sign in to the app. Blocking analytics storage won’t affect anything you can do. If you’d like us to stop analytics for your account, email info@jacobsargent.co.uk.
If we start using cookies for anything else, we’ll update this notice and ask for your consent first where the law requires it.
