Facebook pictures are gone, status updates never happened, videos removed without a trace, and posts removed discreetly. The best thing is that the other person will never know. And all of the removed pictures, videos and posts are saved in a hidden file that only you know about just in case you realize that you made a mistake and want to reverse the process. Creators Erica Mannherz and Clara de Soto don't see KillSwitch as a vindictive tool, but rather as part of the healing process.
So if you need to start "healing," you can download KillSwitch by clicking on the sourcelink.
