Summary:
ImageEditor.cropImage creates a temporary file when downloading images https://fburl.com/07r68w9s
This temporary file can be stored on external storage on android. External storage is accessible to any other application on the device, which could possibly leak images.
Using external storage may be unavoidable. I've voiced my opinion and solicited others on T31548988. Once a good policy is agreed upon, we can implement it.
For now, I'm adding this comment to make it explicit how images are cached.
