Is there a service or platform that will allow me to send a picture that will literally only allow the recipient a glance? Something in the style of This Link will Self Destruct. I see Alpaca Get, but their minimum timer is 3 minutes which I fear will allow for a screenshot. Or if you can suggest a method I would appreciate it
Only send online what you are comfortable for the recipient to save and preserve permanently. There is no way to stop the photo being saved, the person could use a Android emulator and screenshot on host OS for example
If dealing with someone that is not tech savvy enough to defeat disappearing messages, then use a messenger like Signal with disappearing message support. Disappearing messages for (either text or media) is decent protection against the message being leaked (e.g. forensics if police take the recipient or sender’s phone,) but never rely on them as you might face a malicious recipient, as said above, only send what you are comfortable to be possibly saved and preserved permanently.
