Examples include payment processing, analytics, customer service, hosting, push notifications, cloud storage, file format conversion, and speech-to-text. These service providers may access personal information needed to perform their functions, but may not use it for other purposes.

Except as described above, if your personal information may be shared with third parties, you will be notified and given an opportunity not to share that information.
