Yes — this tracker uses CDC "Learn the Signs. Act Early." milestones (2022 revision) and AAP guidelines, which are the same standards used by health visitors and paediatricians.
Your checked milestones are saved in your browser's local storage. Nothing is sent to any server. If you clear your browser data, your progress will be lost.
