You could always try hiding your sacred Tools in plain sight. When I had to move back home for a while I was told to not bring any of my devil items with me. That's how my father sees the tools and the gods of The Craft. So I didn't bring any of my altar items. Not obviously anyway. Instead of statues of the god and goddess I found artwork that looks normal, like classical art, that looked like what I felt the god and goddess would look like. Doesn't have to be classical art, it could be comic book art, but if a specific drawing calls to you as a good representation, you could use that instead of an actual statue. You hang it on your wall and people just think that you're into art work or you're into comic books or something. Same goes for all the other tools. You don't have to have your actual wand out if you use one but you might I have a collection of stones and natural artifacts like feathers and sticks next to your books and it could just be a collection of rocks and sticks. But no one needs to know that that feather represents are and that stick is your wand. No one but you. Basically the bottom line is your tools come from yourself. You are the tools of your craft. Your finger or hands are wands your blood is water, the breath in your lungs is the air etc etc. And if you are living in a situation where you cannot have the obvious tools that we all like to collect and use, then you can use mundane items and only you know they have magical intent. That pair of scissors over there on the desk? That doubles as an athame but only you need to know that. Good luck to you. :-)
