To reset your installation:

1. Delete Jan from your /Applications folder

2. Delete Application data:

   # Newer versions
   rm -rf /Users/$(whoami)/Library/Application\ Support/jan
   
   # Versions 0.2.0 and older
   rm -rf /Users/$(whoami)/Library/Application\ Support/jan-electron

3. Clear Application cache:

   rm -rf /Users/$(whoami)/Library/Caches/jan*

   kill -9 <PID>
