Developer's response to several of the negative reviews complaining about their data being held hostage:

> Hey, it is just a tiny one time payment, you will never have to pay again :) lf you uninstall the paid app within 2 hours, you are automatically refunded. If you want a refund anytime later just contact us

While I understand and respect the developer's desire to monetize, creating a set of expectations and then pushing an update to require payment for accessing local data feels like ransom. Have to be careful with the trust users place in you.

Data hostage? All of these apps feature easy and painless import/export of data to an open format.

I do not have personal experience and it appears that the f-droid versions have no anti-features, but those comments at Play store were specifically talking about their data being held hostage.
