Where’s my data from free app? – Daily Organizer+ Day Planner Review

I’ve been using this app for many years. When did it become a paid app? And where’s my years of data? What do I do if don’t plan to pay for the app? Shouldn’t “charter” users have free use for testing it for you for all of these years? Please advise.
