How to share an app prototype without the cloud?
I'm currently working on an app prototype (with sketch - If necessary I'll redo it in another software). My problem is that sharing the prototype with some stakeholders seems impossible to me, because of the following:
- I may not upload the files to any cloud.
- I may not host the files on my servers.
How would you share the prototype files in my scenario? Is there any existing app, which can open/display a prototype file sent by mail?
