Everything you enter — names, dates, sizes, measurements — stays on your device, or syncs through your private iCloud if you're signed in. It never goes to our servers. We literally cannot access your data, by design. No ads. No tracking SDKs. No data sold, ever. We use TelemetryDeck — a privacy-respecting, EU-hosted analytics service — to count anonymous events (like "paywall shown" or "0–2 children added") so we know what's working. No personal data, no measurements, no profiles, no IDFA. Turn it off in Settings → Privacy if you'd rather. — — — Questions, ideas, or a kid's odd sizing pattern we should account for?
