Cookies on this site
Here is every third-party service we load, what it stores, and why — nothing runs until you agree to it, and you can change your mind whenever you like.
Nothing loads until you say yes
When you first arrive, none of the services below are running and nothing is stored on your device. They load only for the categories you turn on, and not a moment before — ignoring the banner counts as “no”. Accepting and rejecting are one click each, side by side, and nothing is pre-ticked. Your choice lasts a year, and Cookie settings in the footer changes it any time — including switching everything back off.
What we use, if you allow it
Grouped by the choice that controls it. Each of these is a separate switch on the banner — agreeing to one is not agreeing to another.
Product analytics
Helps us see which pages people actually read, and where the studio gets confusing — which steps get abandoned, how long generation takes. We record IDs and timings, never your photos, prompts, or your child’s details.

When you sign in to make a book
The Once Books studio (the app you use to actually create a book) needs a small number of strictly necessary cookies — to keep you signed in and to protect the forms you submit. These aren’t optional because the app can’t work without them, and they don’t track you across other sites.
