This website

• This website has no user accounts, no contact forms, no newsletter, and no advertising or analytics trackers. It does not set cookies of its own.
• It does not ask for any information about children.
• Like any website, our hosting provider (Render) processes technical data such as your IP address and browser type in server logs, to deliver the pages and keep the service secure.
• The fonts and images are served from our own website. The sales and thank-you pages show trust badges provided by Digistore24, which load from digistore24.com; when they load, your browser connects to Digistore24, which receives technical data such as your IP address. No other third-party services are loaded.

Purchases

When you buy a book, you order from Digistore24, which acts as reseller and processes your payment, invoice, delivery, and any refund. Digistore24 collects the information needed for your order and handles it under its own privacy policy, available on the Digistore24 order form. As the publisher, we receive order details from Digistore24 (such as your name, email address, and the product you bought) so that we can provide support.

Emails to support

If you email us, we use your message and email address only to answer you, and keep it only as long as needed for that purpose and for our legal obligations.

Your rights

Depending on where you live, you may have the right to access, correct, or delete your personal data, or to object to its use. To make a request, contact us at the address above.

Changes

If we add any service that processes personal data (for example analytics or a newsletter), we will update this policy first and ask for consent where required.
