This "[807 Simple Discrimination Practice Program]" is produced by SAC and is provided for free! Some permissions in the development system are enabled by default and cannot be turned off (I have asked the software official). I have not actually used or collected them during development. If you have any doubts, you can not use them. If you accidentally turn them off and cannot turn them on, please go to "[Settings]" > "[Application]">"[Permission]">Change settings!
