title: Health Kit reading permission
body: <p>I have a app which writes active calories data to health kit. To prevent duplication of data writing in health kit i read health kit active calories to check if one instance already exsists.</p>
  
  <p>I was under the impression that to read active calories from health kit we need to ask user permission to read active calories.</p>
  
  <p>But after some testing i have observed that i am able to read the active calories data from health kit without getting the user permission.</p>
  
  <p>Is this normal behaviour, that i am able to read data from health kit without the user permission beacuse i have written it?</p>
  
  <p>Should i continue with this implementation or is this a bug?</p>
