I believe you have confused us with a different plugin; we do not force you to upgrade at any point if you have objections.
We do have a Free Plan. I am sorry that our Free version does not fit your needs. Our Free Plan should help you test the features initially. You do not have to upgrade the plan unless you want to try our paid features. You can find details of our free plan feature here.
