Literally ask for permission. That's what Apple does, as does almost every other traditional desktop software developer. On first launch, or when an error occurs, or when some other event that would involve sending personal/usage data to Apple occurs, they:

- Ask if you want to send the data

- Provide details on what kind of information will be sent (including, in some cases, providing access to the data itself)

- ... and usually give you the option to always send that kind of data
