A friendly reminder that there is only one messenger out there which ticks all but the last two boxes.
And those two boxes are, as the author rightfully points out: placebos. You can remote delete the message â but you can't delete the screenshot the receiver made.
Threema is also the only one which is not âfree of chargeâ. So you have to ask yourself: Is your privacy and security worth a one time payment of $5?
