No need to charge, even if you use it, you don't need to charge. Almost every paid software has a probation period! You can use a certain amount of time! Are you afraid of deducting money as soon as you open it! It's okay! Don't want to pay, you can use it after it expires! Will not automatically deduct your money! And many charging software have free versions, which can also be used! It's just a little less functional! In short, as long as you don't want to pay, the software can't be used at most, and the software company won't treat you badly!
