This app acts like an Unlock Key for version 3.1 and newer of the "Delayed Lock" app.
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.
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
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.
I'm very sorry for the inconvenience, but it has become really difficult to maintain both the paid and the free version of the app. If you have any issues or questions regarding the new license model, feel free to contact me.
