Want sex toys but paranoid?

I have come to a point where I’m ok with getting a sex toy, in fact, I really want one. But I live with my family and I share a joint bank account with my mom. So I’m paranoid to buy online even if I had a visa gift card. Like my mom could see it in wifi history(is that a thing?) or it would remain in my search histories? But then I would probably want to be buried alive if I went into an actual store to buy one. I also just don’t know where I would hide it, family barges into my room all the time, goes through my stuff, etc. and before you tell me it’s not worth it then…I’m desperate. Please help.
