During checkout, we collect your name and email address to process the order and deliver your e-books. Payment details are handled securely by Polar and its payment providers and are never stored by Kozmikus.
How we use your data
We use your checkout information only to complete your purchase, deliver your books, provide support, and maintain legally required transaction records.
Cookies and analytics
The site stores your cart, language, recent book views, AI guide answers and recommendations, reading feedback, and a random reader-journey identifier on this device for up to 60 days.

We do not send form contents, payment details, or session recordings to PostHog, and we do not create PostHog person profiles.
