Privacy policy
Data controller: MOONBERRY SLU. Last updated 2026.
What we collect
Your account email, your child's first name, age, whether they are a boy or a girl, and chosen language, any companions you save, and the stories generated for you. We never ask for photos, surnames, addresses, schools or dates of birth.
Photos are not collected
By design, WonderZzz never asks for, uploads or processes a photo of your child — illustrations are created entirely from the first name, age and short description you type in yourself.
Who can see your stories
Personalised stories are private to your account by default. They become readable by others only if you create a private family reading link, and that link stops working the moment you switch sharing off. Stories in the free library are curated by us and contain no personal data.
AI processing
Story text and illustrations are generated by third-party AI models on our behalf. Only the details needed for the story (first name, age, language, theme and companion) are sent, and this data is not used to train those models.
Children's data
WonderZzz is a service for parents and carers. Accounts are held by adults; children never sign in. We keep the minimum information needed to make a story feel personal, and you remain in control of it.
Your rights
You can access, correct, export or delete your data at any time. Deleting a story removes its pages and illustrations; deleting your account removes your profile, children, companions and stories. Write to privacy@wonderzzz.app and we will act within 30 days.
Cookies
We use only the cookies and local storage needed to keep you signed in and remember your reading position. There are no advertising or third-party tracking cookies.
