Who handles your data
The data controller is Jose Pereira De Merces. For any question about your data, write to:
What data we collect
- Newsletter — the name and email address you give. They are used only to send you the articles and the announcements of new books.
- Purchases — the email address, the book bought and the payment reference. They are needed to deliver the file to you and to meet tax obligations.
- Contact — whatever you write in the contact form.
Card details never pass through this site: payment is handled by Stripe or by Hotmart, which receive those details directly.
Cookies
This site uses the cookies it needs to work — the session, the memory of your choice in the cookie notice and, only if you press «I liked it» on an article, a random identifier so that it counts once. If you accept in the notice, it also uses measurement cookies from Google (Google Ads and Google Analytics) and Microsoft (Microsoft Advertising), which tell us whether a purchase came from an ad — not to show you advertising on this site. If you choose «Necessary only», those cookies are not stored. You can change your mind by clearing this site's data in your browser.
For how long
Newsletter data stays until you unsubscribe. Purchase data stays for the period tax law requires. Contact messages are deleted when they are no longer needed.
Your rights
You may ask at any time for access to, correction of, erasure of or portability of your data, and object to its processing. Simply write to the address above. You may also lodge a complaint with the Portuguese data protection authority (CNPD) or with the authority of your own country.
To leave the newsletter, use the link at the foot of any email we have sent you. It is immediate and needs no explanation.
Changes
If this policy changes, the date at the top is updated. Significant changes are announced by email to subscribers.
