On some platforms (most notably Android), using the built-in image viewer could cause a copy of a viewed image to be stored on your device. This could cause additional risks to some of our customers.
We have therefore implemented shiny new image viewers for Crypho: both on the desktop, mobile and web versions. Any time you decrypt and view an image, it will be shown temporarily inside the app. And you can of course zoom, pan and rotate the images, just as you’d expect. When you are done viewing an image, it will be removed completely from your device, with no trace remaining.
