### **Solution tutorial**

Google's on-device conversion measurement improves the number of observable
conversions from your iOS app campaigns while keeping users' personal data
private. In this tutorial, you'll learn how the solution works and follow along
with the steps needed to implement it.

#### How does this work?

On-device conversion measurement uses de-identified event data from
your iOS app campaigns to measure app installs and in-app actions while
preserving user privacy.
