Is there an app for a temporary pdf markup

[Android Central Question]

I have a bunch of worksheets in PDF form. I'd like to have them on my phone/tablet so that they can work on them using that. I'd like the app to either automatically not save any writing or have an easy way to return the files to their original form.

Welcome to Android Central! Not sure if this does temporary annotation, but try PDF Max.
