StowForge
Something enormous has to ride inside a rocket. How would you fold it? Try the accordion, then Miura's fold: pull two corners and the whole sheet opens at once. Predict the packed size, run it, and find out which ideas really flew.

How StowForge 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
