This used to be a 5 star review. I used this for quite a few years. Then the developer took a hiatus for a year or 2, and when he came back, he quietly dissolved my lifetime purchase and instituted a monthly billing system. It's a shame I will be moving on. I put thousands of hours into this app. If the developer cares so little about previous, Commitments such as my lifetime membership, then he probably doesn't care about gathering your data. So maybe don't use this app.
