Privacy policy
Last updated: 26 October 2026
This policy explains what personal data Librolux (librolux.com) collects, why, and what you can do about it. Librolux is a business based in Argentina that publishes digital books in PDF. It covers this site, its sales pages and its checkout (pagar.librolux.com). For anything about your data, email hola@librolux.com.
1. Purchases
Payments in US dollars are processed by Whop, the payment platform: only Whop sees your card details, and it handles them under its own privacy policy. To deliver your PDF and help you, we keep your name, your email address, your country and the order details (what you bought, what you paid and the order number). We use them only for that, for refunds, and to meet our legal and tax obligations. We never sell or rent your data.
2. Emails
We send our emails through Resend:
- the email of your purchase, with your download links, and, for anything bought as a pre-order, the email on the day it arrives;
- if you started a purchase and didn't finish it, a reminder after 3 hours and, the next day, a one-time discount;
- if you bought, a discount on the extras you didn't take after 2 days, another of our books at a discount after a week, and a request for your review after 3 and 10 days.
Every one of those emails has a link to stop receiving them. You will still get the email of any purchase you make.
3. Reviews
If you review a book, we publish it on our pages only with your permission, with the name and city you choose, never with your email. If you add a photo, we keep it private until we check it: we cover the face of any child and remove your phone's data such as the location, using Gemini, Google's AI service, to find the faces. We take it down whenever you ask.
4. Cookies and measurement
Our pages set a first-party cookie (ed_vid) to count visits and know which ad each visit came from. They use this site's Meta pixel and the Meta Conversions API to measure our ads on Facebook and Instagram: they record events such as a page visit, starting a payment and a purchase, with technical data (browser, IP address, cookie identifiers) and your email encrypted with a hash. We never send the book's title or topic. Meta handles this data under its Privacy Policy. We also use Microsoft Clarity to see how our pages are used (clicks and scrolling) and improve them; it hides what you type in forms and handles the data under the Microsoft Privacy Statement. You can block cookies in your browser and limit personalised ads in your Meta ad settings.
5. Where your data goes
To run the shop we use providers outside your country: our hosting provider, Whop (payments), Resend (emails), Meta (ad measurement), Microsoft (Clarity) and Google (Gemini, only for review photos). They process the data for us, under their own security and privacy terms.
6. How long we keep it
We keep purchase data while we need it to support you and for as long as the law requires. Visit data is deleted after 180 days.
7. Your rights
You can ask us to access, correct or delete your data, or withdraw your consent to our marketing emails, by writing to hola@librolux.com with the subject "Personal data". We reply within 10 working days. If you are not happy with our answer, you can complain to your data protection authority (in Singapore, the PDPC; in Malaysia, the JPDP; in Hong Kong, the PCPD; in South Africa, the Information Regulator).
Survey after your purchase
After you pay we show you three optional questions: what you bought the book for, what you do, and which other topic you would like us to publish. We never ask about your health, your age or your phone number. We use the answers only to choose our next books, always as totals and percentages. The legal basis is your consent, which you give by answering; if you don't answer, nothing changes. We keep the answers with your purchase for 24 months and then delete them. To group the topics buyers write we use Claude, Anthropic's artificial intelligence service, without your name or email. You can ask us to delete your answers at any time by writing to hola@librolux.com; if you ask us to delete your data, we delete them too.
8. Changes
If we change this policy, we publish the new version on this page with its date.
