Who we are
Onceling is operated by Martin Jewell, [Street Address], [Postal code, City], Germany. As the operator, I am the controller responsible for the personal data processed on this site. You can reach me at any time at [email protected].
What we collect
Your account details (email address, optional display name and avatar), the book details you enter (the child's first name, age, interests and the dedication), the photos you upload, the content we generate for you (story text, illustrations, audio narration), and order data such as your shipping address and order history. Payments are processed by Stripe — we never see or store your card details.
Your photos
We do not keep your photos. Uploaded photos are used solely to create your book's illustrations and are deleted automatically as soon as your book has finished generating. Only the generated artwork remains. If you tick "Save my photos for next time", we keep them in your account so you can reuse the same characters in future books. You can switch this off at any time in Settings. Your photos are never shared, never used for any other purpose, and never used to train AI models.
How we use your data
We use your data to create and deliver your personalised book, to fulfil print orders, to send transactional emails such as order confirmations and book-ready notifications, and to provide customer support. We do not use your data for advertising.
Who we share data with
AI providers receive your photos and book details only to generate your book. Stripe processes payments. Our print partner receives the recipient name and shipping address for physical orders. Our hosting providers store data on our behalf. We never sell personal data.
How long we keep data
Account data is kept for as long as your account exists. Generated books are kept so you can re-read and re-download them. Uploaded photos follow the photo policy above. Order records are kept for as long as the law requires.
Your rights
You can request access to, correction of, or deletion of your personal data, ask for a copy in a portable format, and object to or restrict certain processing. Email [email protected] and we will respond. You also have the right to lodge a complaint with your data protection authority.
Children
Our service is intended for adults. Details about children are entered by the purchasing adult, who is responsible for having the right to share them. We only use these details to create the book.
Cookies
We only use cookies that the site needs to work: your sign-in session and your language and currency preferences. We do not use advertising or tracking cookies.
