Safety & data

We collect as little as we can, and share it with no one

YubiKids is built to the rules for children’s apps in the US, Europe, the UK and Indonesia, and to Apple’s and Google’s requirements for kids’ apps. Here is everything, in plain words.

Your controls

Consent first

We ask a parent or guardian for consent before any child profile is created, and ask again if our notice changes in an important way.

Export everything

Download all your family’s data as files from the app at any time.

Delete everything

Delete your account from the app. Access ends immediately, and all personal data is erased within 30 days.

Data stays in your region

Families in the EU have their personal data stored in the EU.

How we protect it

  • Encrypted connections everywhere
  • Each child device signs its requests with its own cryptographic key; there are no shared passwords
  • Your parent PIN is stored only as a protected hash and never leaves the device in readable form
  • Backed-up drawings are private and reached only through short-lived links
  • No passwords are stored at all: you sign in with a one-time email code, Apple or Google

About AI in YubiKids

Activities, illustrations and voice-overs are created with AI assistance, following characters and a style our team designed by hand. Every activity is reviewed by a person before children see it, and every math answer is checked by code. Science, nature and geography facts are checked against a cited source. Children never talk to an AI. If you turn on weekly summaries, only anonymous skill scores are used, never your child’s name or drawings.

Built to meet these rules

We design YubiKids to meet the requirements below and have each region reviewed by legal counsel before we launch there.
