I am ridiculously excited about my latest project: a children’s picture book about privacy called Privacy, Please! You can check it out and order a copy at privacypleasebook.com.
The idea for the book
Let me tell you about how this book came to be…. I decided to write this book about a year ago, in Fall 2024. The Privacy Engineering masters program at CMU was planning an International Data Privacy Day 2025 event at the Carnegie Library in Oakland, and I asked the librarians if I could read privacy books to kids during a preschool story time. The librarians agreed, but did not have any suggestions for privacy-related picture books to read. They suggested a book on limiting screen time, and I found some books on bodily privacy and other very narrow aspects of privacy. I suggested a story for 7-12 year olds about the harms of surveillance, The Eyemonger, written by privacy law scholar Daniel J. Solove. The librarians thought it would be too long and too scary for preschoolers. I reached out to Dan and other privacy professionals in search of a book on privacy four younger children. But nobody had any good suggestions.
Back in 2014, I had worked on a project in which I asked people to draw pictures of what privacy means to them. I visited schools and community events, asked my friends, and even bought some drawings from crowd workers. I built a website called Privacy Illustrated that now has hundreds of these drawings. A few years later, my students systematically analyzed the drawings and wrote a research paper about the trends they observed. I’ve tagged the Privacy Illustrated drawings with some metadata about their content and the age of the artists. So while I was pondering picture books about privacy, I took a look at the drawings from some of our youngest contributors to see what privacy meant to them.

I saw drawings of young children in their rooms, snuggled under blankets, hiding from their siblings, playing with friends in a private space, and enjoying privacy in the bathroom (interestingly, many adults also drew bathroom pictures!). I saw that privacy was a concept that young children seem to begin to understand in preschool, and I wanted to write a book to help them make sense of it.
As a parent of three (now young adult) kids, I’ve also observed that young children sometimes need a “time out” and that they can benefit from some private time to themselves. Giving them the words to ask for privacy rather than waiting for it to be imposed on them can be helpful. I’m hoping that the examples of how the characters in the book achieve privacy can stimulate discussion between children and adults and help young children find appropriate ways to achieve privacy in their own lives. I also hope that the adults reading this book to children will find something to take away from it!
As a privacy researcher who often focuses on online privacy issues, I thought about including these in the book. However, I realized that young children have limited online interactions, so I was tempted to leave online issues out altogether. But I also realized that some mention of online privacy issues could help prepare children for going online, and it could be useful in educating the adults in their lives to think about online privacy issues. In the end, I touch only lightly on online privacy, but in ways that I hope will be relatable to young children and that may lead to more conversations as children grow.
Workshopping early drafts
I wrote the text for a first draft of a book in which a young narrator talks about privacy at home, at school, and out in the world. I found images from the Privacy Illustrated collection to illustrate some of the pages, and then tried using some generative AI tools to fill in what was missing. I quickly realized that to get the sort of look and feel I was after, I would need to hire an illustrator, but the images that I had were useful as a placeholder to start getting some initial feedback on my draft. I showed my draft to my young adult children and other family members and they were all enthusiastic about it. I shared the draft with some friends who have young children, and even borrowed a couple of children to read it to, and reviews were positive.
I printed out my book draft and put it in a loose-leaf binder to read on Privacy Day at the library. I also brought The Eyemonger to read. The children and parents enjoyed both books. I discovered that preschoolers will sit through The Eyemonger, and those I read to did not find it scary at all. While the adults thought the character who looks like a dinosaur with 1000 eyes was rather creepy, my young audience thought he was kind of cool. That said, I think the older kids learned more from the Eyemonger book than the younger ones, and they seemed to be pretty engaged with my book. The parents I talked with were all very impressed with my book and encouraged me to finish it and get it published. The kids seemed to like my book, and seemed to especially like the animals in the book. But one child told me it wasn’t a real book because it didn’t have a properly illustrated cover. I decided to keep working on it and turn it into a “real book.”

I reached out to the Carnegie Mellon Children’s School (the lab school at CMU where my three kids all attended preschool and kindergarten) and asked if I could workshop my book with their educators. They agreed, and I was delighted to spend an hour with them a few weeks later. The teachers gave me some great feedback about the flow of the story. They suggested adding some specific phrases children could say to ask for privacy. And they reminded me that young children are limited in the amount of privacy they can realistically achieve because they are almost constantly under adult supervision. This is especially true in preschools, which often don’t have bathroom doors. The teachers shared some of their approaches to offering privacy to children while still being able to supervise them. I made substantial revisions to the book after my session at the Children’s School.
I made several other changes to the book based on feedback from multiple people. I shortened it a bit, reducing three outdoor privacy scenarios to one, removing a page about parents wrapping gifts in private, and tightening up some of the wording. In early drafts, the protagonist’s dog finds privacy in a dog house, but a friend pointed out that these days, dogs are more likely to find privacy under beds, so I updated the book accordingly. I originally included a page about superheroes going into phone booths to put on their costumes, but today’s kids have never seen a phone booth, and apparently, superheroes can now put on their costumes at the touch of a button. Nonetheless, I just couldn’t let the superhero costume concept go, as it was inspired by an adorable drawing from a five-year-old who explained that Spiderman needs privacy to put his costume on. In the final version the protagonist, who wears a purple cape throughout the book, hides in a closet to change into a superhero costume.
