Privacy Policy
Last updated: 17 October 2026
I am Leo Di Lux, an author of dark historical thrillers. This policy explains, in plain language, what information this site collects and what happens to it.
What I collect
When you sign up for my newsletter or claim a free book, I collect your email address, the first name you choose to give, and basic signup context such as which page or advertisement brought you here. The site also uses cookies from Meta, Pinterest and Kit to measure how people find these pages. When you arrive from one of my letters, Kit’s tag can connect that visit to your subscriber record, so that I can see which letters lead to sign-ups and sales. Visitors from the United Kingdom, the European Economic Area and Switzerland are asked first, and anyone can turn them off on the cookies page. Kit, which sends my letters, records whether each letter is opened and which links are clicked, along with the approximate location of the device used, as every newsletter platform does. It may also add a small amount of information about you from outside sources, described below under “Information from other sources”.
What I use it for
Your details are used to deliver the books you request, to send you my newsletter, and to let you know about new releases, campaigns, and offers from me. Nothing else. I do not sell, rent, or trade your information, and I do not send email on behalf of anyone but Leo Di Lux.
Advertising audiences
To keep my advertising honest, Kit shares a scrambled (hashed) copy of subscriber email addresses with Meta. Meta uses it only to recognise which of its users are already on my list, so that I can stop showing them advertisements for a book they already have, and to find new readers whose interests resemble theirs. Meta cannot read the addresses, and they are used for nothing else. If you would rather be left out of this, write to me and I will remove you from those audiences while keeping you on the list.
Information from other sources
Kit, the platform that sends my letters, offers a feature called Subscriber Signals, which I have switched on. For each active subscriber, Kit matches the email address against records held by outside data companies and public sources, when the address first joins my list and again as more data becomes available. Where it finds a match it may add details such as a job title, company, industry and education, a short public biography, public social media profiles (for example YouTube, Instagram, X and LinkedIn) with their follower counts, and labels Kit derives from these, such as whether someone appears to be a founder or executive, or to have a large following. For readers in the United States it may also add demographic estimates drawn from postal records: age range, gender, household income and home ownership. Kit pairs these details with its own record of which of my letters you open and click. Many addresses return nothing at all. I use what comes back only to understand who reads my books and to judge what is worth writing to you about. It is never sold or passed on, and I will not use it to contact you anywhere other than the email address you gave me. My basis for this is my legitimate interest in knowing my readership, and you may object at any time: write to me and I will have Kit remove those details, or delete your record altogether if you prefer.
Who processes it
Your data is stored and processed by the trusted services that run this operation: Kit (email newsletter platform, together with the outside data companies it uses for the information described above, which are given the email address in order to match it), BookFunnel (book delivery), StoryOrigin (promotional book delivery), SparkLoop (the referral programme, which records who recommended whom so that rewards can be sent), Payhip (direct sales of my audiobooks; your card details go to Payhip and its payment providers and are never seen by me), Meta (the advertising audiences described above), and Vercel (website hosting). Each processes your information only to provide their service to me, under their own privacy and security commitments.
Your rights
Every email I send includes an unsubscribe link, and unsubscribing always works immediately. You may also ask me at any time to show you the information I hold about you, correct it, or delete it entirely. That includes the right to object to the advertising audiences and to the information from other sources described above, both of which I will honour on request. Under UK and EU data protection law you have the right of access, rectification, erasure, and objection, and the right to complain to a supervisory authority such as the UK Information Commissioner’s Office.
