Another guy who signed up just to post here.
I am a long time user of CCleaner free version, but I open the program very rarely. Today, I was surprised to open it and found out that it was turned into a trial of the Pro version. I didn't like it at first, but it turned out to be a good marketing strategy for Piriform because I found many useful features that can really help me out.
I was about to buy the Pro version when I noticed a fine print saying it was a 1-year subscription (yes, they are now announcing before you buy). There is also an "automatic renewal" option marked. But here is the weird thing: if I unmark that option, the fine print goes away! Look at the screenshots (in Portuguese, sorry!):
I am not sure what to do. I really want to use the features I had experimented and will even consider to pay the subscription fee, but it's still not clear to me what is that non-auto-renewal purchase option. I also didn't get what's the diference between the free and paid version. Some people here mentioned the only difference is that I have to manually update de software myself in free version. Is that accurate?
