Who we share it with

We do not sell your data. We share it only with the services that help us run this site and our products:

Substack (newsletter). GoHighLevel, run for us by our marketing partner Creator Funnels (sign-up forms, emails and follow-up). SendBlue (text messages, only if you opted in). Stripe (payments). GitHub (course access). Cal.com (call bookings). Notion and Slack (handling enquiries inside our team). Resend (emails from this site). Vercel (hosting and privacy-friendly usage stats). Google Analytics (site usage, after consent).

Some of these services are based in the United States. When a service handles your data outside the UK, we rely on the transfer safeguards that service offers under UK data protection law.

Emails and text messages

Every marketing email has an unsubscribe link. To stop text messages, reply STOP to any message.

How long we keep it

Sign-up details: until you unsubscribe or ask us to delete them.

Customer and payment records: six years, because UK tax law requires it.

Enquiries and applications: only as long as we need them to reply and follow up.

You can ask to see, correct, delete or move your data. You can object to how we use it, or ask us to limit it. You can withdraw consent at any time.
