Are AI personalised children’s books safe? What to ask
The Once Books team · 14 August 2026 · 4 min read
It’s the right question to ask before uploading a photo of your child anywhere. Here’s how Once Books handles it, and the questions worth asking of anyone else you try.
Are the photos used to train AI?
Not here. Your child’s photos are used only to build that book’s character references. Our AI providers are contractually prohibited from training on them, and you can delete them at any time. Our child safety page has the full detail. If a service won’t say plainly whether uploads become training data, treat that silence as an answer.
Who can see the finished book?
Finished books are private by default. A share link is long and unguessable, and a book only becomes public if you choose to make it so. There’s no public gallery your child turns up in by accident.
What about the pictures the AI generates?
Both the photos going in and the pages coming out are moderated for safety, so the book stays age-appropriate. Nothing is final until you approve it, page by page.
Two practical follow-ups: the photos you should upload, and the direct answer to “are my child’s photos used to train AI?”.
If you’d like to see what you get before uploading anything, flip through a finished sample first. Every page is private to you until you decide to share it.
