Update ruined the app for me!

I was using this app all the time, getting notifications when a birthday was approaching. Then they do an update and I go to open it and all my saved information is gone. I can not find a way to recover all the dates I had saved. And now its full of ads and you have to pay just to have simple options. Ridiculous. Lesson learned. Put the dates in my phone calendar and let it do the work....for free. Why pay for something you already have for free on your phone?
