body: I am working on a mobile application. It uses a third-party service (let's call it *XYZ*) which in its ToS has stated
  
  
  
  > 
  > Use the *XYZ* Platform to develop and distribute non-commercial
  >  Streaming SDAs that comply with the Branding Guidelines (i) for
  >  private personal use (ii) on Approved Devices (iii) by *XYZ* users who
  >  are subscribed to the Premium Service (as defined in The *XYZ* Terms
  >  and Conditions of Use).
  > 
  > 
  > 
  
  
  My use case falls under the definition of *Streaming SDA*
  
  
  Now, my application will be free to download and use the features that said service offers, without any restrictions whatsoever, but I want to include the in-app purchase which unlocks some other features in my app, mostly related to the interface and some minor features. 
  
  
  **The locked features have nothing to do with the third party service**, so if I understand correctly I do not profit from using the service in my app. The in-app purchase is entirely optional for users, they are not forced to buy it in any way and the free version of the app is perfectly usable.
  
  
  
title: Does this fall under the "Commercial usage" definition?
