Mobile apps
These guides cover the questions a mobile app raises under US privacy law: which federal and state rules apply to the data it collects, what its privacy policy and terms must say, and how its store labels and its partners (analytics, advertising and other code it ships with) fit in.
Health data and children's data carry the strictest rules, and both have changed in 2025 and 2026. Each guide states the date its law was last checked.
