It will not let me.
Thank you for your question.
I assume that you cannot delete F-Secure SAFE app from your android device after the removal of a child profile that the program was installed from.
As the parent, log in to My F-Secure portal, click on the device you wish to uninstall F-Secure from and click on Release License. Confirm the release then go on the device and try to uninstall SAFE again.
You would probably also need to put your android device to safe mode. After that, you can uninstall F-Secure SAFE app. You will need to consult the phone manufacturer how to restart your phone in safe mode.
It is advisable to release the license first before deleting the child profile app.
