If at all possible and if you need to, I would advise using a cell phone for Spiritual Satanist related things if you have snooping parents.
Chances are you parents may be influenced by the enemy to snoop on you especially if they are Christians which makes them almost 100% able to be either possessed tricked, or manipulated into snooping or other unpleasant things that may happen such as interrupting meditation or yoga etc..
Just don't be to mad at them it would hardly be their fault, furthermore, you will want to avoid conflict because the enemy will try to spin this against you, and or other family members. The enemy loves to cause chaos and destruction in the family. Heck, such things are even written in the bible(lie-ble.)
So be careful. Also, anyone in your life, co-workers, or even random people can be manipulated by the enemy against you. Just try to not let it go too far and bother you. People whom are not with Spiritual Satanism are slaves to the enemy. And the enemy will use them however it sees fit. Try to not let it bother you too much. Just shrug it off and get smarter to where it doesn't affect you anymore.
Hail Satan.
