What we collect

When you buy a book we collect your name, email address and country, plus the payment record our provider returns. On the waitlist we collect your email address only. Card numbers are entered on the payment provider's page and never reach our systems.

Why we hold it

Your email is how we deliver the download link and any replacement link later. Order records meet tax and accounting duties. Waitlist addresses are used for launch news and nothing else.

Who processes it

Payments are handled by our payment provider, email by our email provider, and hosting by Relume. Each holds only what its job requires, under contract, and none of them sells your data.

How long we keep it

Order records are kept for seven years, as accounting rules require. Waitlist addresses are deleted after the launch message, or immediately if you ask before then.

Your rights

Email hello@zentesto.online to ask for a copy, a correction or the deletion of your data. We answer within 30 days. If our answer does not satisfy you, you can complain to your local data protection authority.
