Hi, one of the authors here. A good chunk of the core is from my python Snapchat API(https://github.com/pencilo/pysnapchat) which lets you do things like download snaps and send snaps.

You are correct that it is impossible for them to stop you from downloading the image and saving it. Images are encrypted on upload but they are encrypted using a fixed key in AES-128 ECB, so it doesn't do any good.

The simple truth with Snapchat is they cannot make it impossible to download and save the images without trusted computing support(which they wont get).
