It is often a good practice to use portable apps for many reasons. I took the following content from portableapps.com website that distributes 400 plus portable applications. 

Perhaps, millions of people use portable apps every month.

A portable app is a computer program that does not need to be installed into Operating System like traditional apps, so you can carry it with you on a portable device or a cloud drive and use it on any computer. When your USB flash drive, portable hard drive, or other portable device is plugged in or your cloud drive is synced, you have access to your software and personal data, just as you would, on your own PC. And when you unplug the device, none of your personal data is left behind.

Here are few guidelines on how portable apps would behave.
