you have to read it in context…
(though I am not a lawyer, nor do I play one on TV, this is also not my first time reading a legal document)
first, the policy is about your (ie Corona Labs, “our” in context) privacy practices, not those of the developer:
Please read the following to learn more about our privacy practices (“Privacy Policy”).
and by services, they mean Corona Lab’s services, not some other analytics service used by the developer:
By using a mobile application that incorporates or utilizes Corona Labs’ services (collectively, the “Services”) you accept the practices outlined in this Privacy Policy.
so remember that word “Services” - it has a specific legal meaning as defined by this context.
third, and incontrovertibly finally, the policy is about the info “that Corona Labs gathers”, not what the developer may (or may not) gather using other means:
This Privacy Policy covers Corona Labs’ treatment of personally identifiable information (“Personal Information”) that Corona Labs gathers when you access or use the Services.
thus when the policy says that developer may optionally collect data using the “Service” (as defined earlier, and note the continued capitalization here), it’s not talking about someone else’s lowercase “service” that the developer might chose to use. (say, for instance, the use of Google Analytics is not covered by this policy)
But all that legal wording aside: it would suffice just to have a clear statement of whether (or not) there are ANY analytics collected by Corona Labs that CANNOT be disabled by the developer.
