ShelfPals
A free leveled reading library for ages 6–8 — read up from Sprout (sound-it-out) to Grower (little stories) to Reader (bigger stories), with read-to-me and tap-a-word. Earn a Reading Passport stamp for every book you finish AND tell back — never for minutes on a clock. On-device; nothing leaves your device.
▶ Play it nowBuilt for sittings of about 15 minutes on the screen. That is our design budget, not a measurement.

How ShelfPals 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
