Why would I need a credit card on file for the Free plan?

The card is on file just in case you are ever interested in upgrading your plan from free to paid.

There is absolutely no pressure to ever do so unless you are interested in using one of our paid products and we will never charge the card unless you've signed up for one of the paid plans. We offer completely free services and you don't ever have to worry about paying a penny with our free forever plan.
