Quoting from Scrambled Exif Page on F-Droid
Scrambled Exif (pronounced eggsif) helps you remove the metadata in your pictures before you share them. If you don't want the big Internet companies (or whomever) to know were your pictures were taken don't forget to remove the metadata from them before you share them.
I have also examined the app's code as of today (April 10, 2018) and found no malicious actions. This application can be trusted and installed
I've tried it 3 months ago. The app crashes when I try to open the image with it. Seems that latest update has solved the issue. Works fine now
