Privacy Policy
LittleStacks is a small app made for parents. We keep what we collect to the minimum we need to make the app work for your family, and we don't sell or rent any of it.
What we collect
When you create an account we store your email address (or your Apple Private Relay email, if you Sign in with Apple). When you scan a book or add a kid we store the book metadata, your kid's first name and birth month/year, and the photos you upload of your shelves and kid avatars. When you log a reading session we store the date, the book, and the kid.
How we use it
Your library, kids, and reading log are used to power the app for you and anyone you invite to your family. We use AI to (a) identify book titles from your shelf photos and (b) recommend what to read tonight. Your kid's first name may be passed to our AI providers (Anthropic via AWS Bedrock, and Google Gemini) so the recommendation can mention them by name. These providers process the prompt under data-processing terms that prohibit training on, retaining, or selling the data.
What we never do
We do not put kid names, parent emails, reading logs, or any other identifying information into analytics or crash reports. We do not sell your data. We do not track you across apps or websites. We do not show advertising.
Children
LittleStacks is a parent's tool. The app is not designed for children under 13, and we do not knowingly collect personal information directly from children. If you believe your child has signed up, please contact support and we'll delete the account.
Sharing
The only people who can see your family's books, kids, and reading log are you and the co-parent you explicitly invite to your family. Our service providers (Supabase for storage, RevenueCat for subscription billing, Apple for sign-in and payments, Anthropic and Google for AI) process data on our behalf under their own privacy commitments.
Your rights
You can delete your account at any time from Account · Delete account inside the app. This permanently wipes your library, kids, reading log, and any photos you uploaded. You can also email us to ask what we have on file or to request a copy. We will respond within 30 days.
California (CCPA)
If you live in California you have the right to know what personal information we have, to delete it, and to opt out of any sale or sharing of personal information. We don't sell or share personal information, but you can still exercise your other rights by emailing support@getlittlestacks.com.
Changes
If we change this policy in a way that affects what we collect or how we use it, we'll show you a notice the next time you open the app.
