CreasePals
Learn to read a folding diagram. A dashed line means fold toward you; dash-dot means fold away. Look at the picture, make one fold, then pick which picture looks like yours. Fold a cup, a puppy, a paper hat and a fortune teller.

How CreasePals handles your kid's data
- ✅ All progress, settings, and AI-generated content stays on the device
- ✅ No analytics, no tracking, no third-party SDKs
- ✅ Free — no ads, no in-app purchases
- ✅ No personal information collected from children — in line with COPPA (updated by the 2026 FTC amendments)
- ✅ No chat with strangers — play-together rooms use a short code and preset emotes, never typed messages
