Privacy Policy
Last updated: October 20, 2026
Who we are
Curiosity 4U publishes puzzle and activity books, sold on Amazon. This website is curiosity4u.com. Curiosity 4U is operated by T3 Evolution AB, Sweden.
If you have questions about this policy or your personal data, contact us at hello@curiosity4u.com.
What we collect and why
Free bonus downloads. When you sign up for a free bonus (for example, extra puzzles linked from one of our books), we ask for your first name and email address. We use them to:
- send you the bonus download link
- occasionally tell you about new books and free extras from Curiosity 4U
We only send you emails after you confirm your subscription (double opt-in). Every email has an unsubscribe link, and you can unsubscribe at any time.
Website visits. Like most websites, our server records basic technical data such as IP address, browser type and the pages visited. We use this to keep the site secure and working. If we use analytics, the data is aggregated and is not used to identify you.
Analytics. With your consent, we use Google Analytics to understand how visitors use this site, for example which pages are visited and how visitors find us. Google Analytics sets cookies only after you accept analytics cookies in our cookie banner. You can change your choice at any time.
Contact. If you contact us by email, we keep your message and contact details so we can reply.
Legal basis (GDPR)
- Consent: for email signups and analytics cookies. You can withdraw consent at any time.
- Legitimate interest: for website security, basic statistics and replying to messages.
Who we share data with
We do not sell your personal data. We use a small number of trusted service providers that process data on our behalf:
- MailerLite: email signups and delivery
- Google (Google Analytics): website analytics, only with your consent
- Our web hosting provider: hosting this website
- Amazon: links to our books and to leave a review take you to Amazon, which has its own privacy policy
Some of these providers may process data outside the EU/EEA. When they do, appropriate safeguards are used, such as the EU Standard Contractual Clauses.
Cookies
This site uses the cookies needed for it to work, such as login cookies and a cookie that remembers your cookie choice. With your consent, Google Analytics also sets analytics cookies. Signup forms hosted by MailerLite may set their own cookies. You can change your cookie choice at any time, or block or delete cookies in your browser settings.
How long we keep data
- Email subscribers: until you unsubscribe. After that, we keep only what is needed to respect your opt-out.
- Server logs: a limited period for security purposes.
- Analytics data: up to 14 months in Google Analytics.
- Messages: as long as needed to handle them.
Your rights
Under the GDPR you have the right to:
- access your personal data
- correct it
- have it deleted
- restrict or object to its processing
- data portability
To use any of these rights, email hello@curiosity4u.com.
You also have the right to lodge a complaint with the Swedish Authority for Privacy Protection (IMY), www.imy.se.
Children
Our books are for all ages, but bonus signups are intended for adults. We do not knowingly collect personal data from children under 16. If you believe a child has signed up, contact us and we will delete the data.
