It worked for years with no/few changes. Then the price increases and pro features stop working. I'm not too likely to give the devs the benefit of the doubt. Patch out the 'pro' check and release an update. Or reply to one of the many new 1 star reviews and say you lost access to the source code, if that's what happened.
Complete silence + taking money...
I still don’t get it. You say it yourself that it worked for years with no issues. Current behavior is bad but the community pirating the app does not seem right either.
Popular apps get away with more user hostility and price gouging. To me this effort seems misplaced.
They seem to have pulled it, I can't find it on my Pixel.
I paid for it in 2014, and it hasn't been updated in about half of that time, they removed the cloud key backup at some point without notification so I lost all of the keys I had stored, and last time I used it, it didn't even recognise I had paid for it.
I moved to a different app a while back.
