title: What is the best way to track iOS SDK usage?
body: <p>I would like to get a statistics on how many people are using SDK that I'm providing. What functions they use the most and etc. </p>
  
  <p>For apps I used firebase/fabric in order to track all that. But those services come with a responsibility (privacy policy). And if I just pack them into SDK that may conflict with people apps who don't want any tracking SDK being included in their Apps. </p>
  
  <p>So the question is, are there any services that provides SDK tracking without violating privacy policy of user data collecting? </p>
  
  <p>So far I was not able to find any of those specifically for SDK. </p>
  
  <p>As a side question, If such analytics is taken place in SDK, should it be explicitly written in SDK description?. And should the people who integrate such SDK <strong>explicitly write</strong> in their app description that particular SDK is collecting their usage?    </p>
