Who we are

guthealthcookbook.com is run by Longevia Group Ltd, registered in England and Wales, company number 16793530, 124/128 City Road, London, EC1V 2NJ. We are the data controller for personal data collected through this website. Contact: [email protected].

What we collect and why

Your email address, if you join the Launch List. We use it to send you The Gut Health Starter, news of the book’s launch and occasional news from Longevia. Our legal basis is your consent, which you can withdraw at any time using the unsubscribe link in every email.
Your email address and reader code, if you request the 10-Day Gut Health Reset downloads. We use them to check the code and email you the downloads (or tell you if the code didn’t match). Our legal basis is that you asked us to send them. We won’t send you newsletters or marketing because of this request alone.
Your news preference, if you tick the box on the reset form. We then send you occasional news and recipes from The Gut Health Cookbook and Longevia. Our legal basis is your consent, which you can withdraw at any time using the unsubscribe link in every email.
Messages you send us, so we can reply.
Basic technical data, such as your network address, which our hosting provider processes briefly to deliver the site and keep it secure.

We don’t use advertising or tracking cookies on this site.

Who we share it with

MailerLite stores Launch List subscribers and reset requests, and sends our emails. EU Standard Contractual Clauses apply to any transfers. MailerLite privacy policy.
Cloudflare hosts the website. Cloudflare privacy policy.
Google Fonts supplies the typeface, so your browser contacts Google to load it. Google privacy policy.

We never sell your data.

How long we keep it

We keep your email address until you unsubscribe or ask us to delete it. If you only requested the reset downloads, we keep your email address and reader code for up to 12 months so we can resend them if you ask, then delete them. We keep messages for as long as needed to deal with them.

Your rights

Under UK GDPR you can ask to see, correct or delete the data we hold about you, object to how we use it, or withdraw consent. Email us and we’ll respond within 30 days. You can also complain to the Information Commissioner’s Office at ico.org.uk.
