When I downloaded the app, it asked for a lot of permissions such as location and network access. Why?

The app asks for the following permissions:

My Location: The NestWatch app uses GPS to tag nest sites.

Full network access: The NestWatch app sends your data to our servers as you collect it. The NestWatch servers send data back to the phone when your data needs updating.

Camera and Photos: The app requests permission to access the camera and local photo albums/pictures so that the app can take, store, and display pictures related to the NestWatch app only.
