Update renders useless

Tried to open app this morning after latest update and it suddenly asking for login - not sure I ever had an account, but no matter what I do they tell me I need to enter a valid password. Why should I be providing personal data when I paid for this app? Also, Im using it bc I have no time, so the wasted time is extra frustrating. Deleting and getting one of the many free versions.
