Great App, Great Support

KenKen is my “Go To” app. I almost only work them on my iPad and primarily 9X Medium level, which I usually solve between 15-30 minutes. I don’t like spending much more time than that on a single puzzle, which is why I don’t do higher level puzzles on a regular basis. I limit my iPhone to 7X Med because of the size of the screen on bigger puzzles. Great for killing time in the doctor’s office. I find KenKen a great way to “clear my head” when I’m overthinking a problem at home or work. After 2 or 3 puzzles, the solution to the problem at hand seems to “pop” into my head. I’ve had a few problems with earlier releases, but the support was great and they addressed them quickly.

Enjoyable and addictive game, but one sad issue...

I ways introduced to KenKen puzzles at school a few years ago and completely fell in love with them and would always do them. I later on found this app and it was perfect for a while, but then ran into an issue. The app only allows you to play 50 puzzles for free, then you have to pay to get more puzzles. I mean, I was super happy while I had those 50 free puzzles, but now I’ve used them all up and can no longer play anymore puzzles, causing the app to no longer have a purpose for me. I would love to buy more puzzles for this, but my parents wouldn’t want to pay for 30 or more puzzles just for it to be 3 days later and having to buy more because I’ve used them all up again. I’ve tried to delete and reinstall the app to see if it would just reset everything and I could just pick 50 new puzzles to do and not care about my old data, but when I reinstalled the app it kept my old data and I still couldn’t play more puzzles.
I want to continue playing this game, but I can’t without purchasing more puzzles, which isn’t really an option for me at this point.

Privacy issue: KenKen Classic reads your clipboard

Beginning with iOS 14, I get an iOS popup ("KENKEN pasted from <app>") whenever KenKen Classic version 2.7 moves to the foreground, telling me that KenKen Classic is reading my clipboard. This is even though I have not tried to paste anything into it. Since KenKen Classic hasn't been updated in about a year, it has been doing this to all of us for at least that long, and silently before iOS 14 started telling us. I'm sure that we all copy and paste information that is no business of KenKen's developer, yet this developer has been silently slurping it all up until recently, for undocumented purposes. Because of this, I am deleting this app until 1) the developer KenKen Puzzle, LLC comes clean on this practice, tells us precisely why and for what purpose it has been doing this, and posts an update that fixes this privacy problem; or 2) Apple releases an updated iOS that gives us the ability to block this type of behavior. (2) may not be enough, given that KenKen Puzzle, LLC has already abused its trust. Do you copy passwords or other sensitive text to your clipboard? Do you copy photos with sensitive GPS location information in them? If so, then you should worry about this too.
