YOUR DATA STAYS WITH YOU No account, no ads, no trackers. Measurements are stored on your device and synced between your iPhone and iPad through your own iCloud account. The developer has no access to any of your data. GOOD TO KNOW ChildArc is a growth log, not a medical device. It does not diagnose anything and does not replace the advice of a doctor or pediatrician. On any chart, what matters is a steady curve.
