If you are a new user: Please install "Delayed Lock" instead and buy the license through the in-app purchase option: https://play.google.com/store/apps/details?id=de.j4velin.delayedlock2.trial

This is only a workaround for users who already have bought the "old" paid app so they don't have to pay again for a license.

For users who have already paid for this app: Please install "Delayed Lock" and this unlocking app. "Delayed Lock" should accept this app as a valid license so you don't have to pay again.
