What's your threat model?
You can't counter someone who wants to store the document -- just take a video of the device.
So what you can do is prevent accidental saving, and keep honest people honest. For this, an expiring link will suffice for text, and other formats can be supported using e.g. data URIs (content isn't cached on-disk AFAIK, unless paged out), serving PDFs as images, etc.
- saimiam 9y agoIf they take a screenshot or video, maybe I can report the action back to sender notifying them that the receiver is not trustworthy. I'm told Snapchat does this for screenshots. I'll look up expiring links but do they need people to upload content to a server first before generating an expiring link? Threat model - none as such. For a person who makes a living writing blogs for others, their threat model is plagiarism. For a startup sharing trade secrets with a VC, the model is violation of NDA and so on. E1: never mind about expiring links. I figured out what they are from the other comment. You mean Send, right?
