Videwatch does not request or store any sensitive user information.
When a video is selected, its data is stored in the iPhone and Apple Watch apps, this includes the thumbnail image and information such as the video identifier, file type, creation date, and duration.
Flurry Analytics, provided by Yahoo, is used to help understand how Videwatch is performing and being used.
Like most analytics services, Flurry uses device identifiers, and information such as IP addresses, to provide data such as usage, user retention, events/actions, country of origin, etc. This information is used to provide statistics and an overview of how the app is being used.
