Privacy

Last updated 25 September 2026

On This Day This Happened is a UK sole trader business responsible for the personal information described here. You can contact us about privacy through our contact form.

Information we use

If you sign up for the free book and newsletter, we collect your email address, subscription status and the social link you used, if applicable. If you contact us, we collect your name, email address and message. Our hosting service also receives technical information needed to deliver and protect the site.

Why we use it

We use your email to confirm your signup, give you access to the book, and send history stories and occasional news or offers when you have agreed to receive them. We rely on your consent for marketing emails; you can withdraw it using the unsubscribe link in each message. We use contact details to answer enquiries and site visit statistics to understand which pages and social links people use. Our lawful basis for those purposes is our legitimate interest in responding to enquiries and improving the site.

Services and storage

Beehiiv manages newsletter subscriptions and confirmation emails. Resend delivers contact form messages. Vercel hosts the site and provides cookie-free Web Analytics. These providers may process information outside the UK; contact us for details of the transfer arrangements. We keep subscription details while you remain subscribed and retain only the information needed to honour an unsubscribe. We keep contact messages only while needed to deal with the enquiry and any related recordkeeping. We do not use automated decisions that have legal or similarly significant effects on you.

Cookies and video

Essential cookies hold your pending signup for up to seven days and, after confirmation, allow access to the downloads for seven days. Your email is encrypted in the pending cookie. Vercel Web Analytics does not use analytics cookies. The YouTube video loads only if you choose to play it; YouTube may then use cookies and collect viewing information.

Your choices

You can ask to access, correct or delete your personal information, or object to its use, through our contact form. You can also complain to the Information Commissioner’s Office.
