We built WoopKid for our own kids. So the privacy policy is the one we wanted as parents.
Game progress (high scores, stickers, unlocked pets, daily streak) is saved in your browser's localStorage, on your device only. It never leaves the device and we cannot access it. Clearing your browser data erases it.
The only third-party request on any page is Google Fonts, which serves the two typefaces you are reading. Games themselves make zero external requests after loading.
WoopKid World is COPPA-friendly by architecture: since nothing is collected from anyone, nothing can be collected from children. There is no data to request, delete, or worry about.
The whole site is static HTML, CSS and JavaScript served from one domain. No iframes to ad exchanges, no third-party trackers, no chat, no user-generated content, no way for strangers to contact students. See our teachers page for the allowlist details.
Last updated July 2026. If this policy ever changes, this page changes. That's the whole mechanism.
