Privacy and tracking rules
Privacy rules shape what you can measure and how you must explain it.
App Tracking Transparency
On iOS you must ask permission before tracking users across other companies' apps and websites. Many people say no, so plan your measurement for that.
Store disclosures
Apple's privacy labels and Google Play's Data safety section describe what you collect. They must match what your app and its SDKs actually do.
Keep it lean
Collect only what you use. Every SDK you add brings its own data collection, and you are responsible for it.
- Checklist
- Privacy labels match your SDKs
