Can other people touch tarot cards?

I've always been curious about tarot cards and their use in divination. I understand that they can be a powerful tool for self-reflection and insight, but I'm wondering about the etiquette surrounding their handling. Specifically, can other people touch my tarot cards? Is there a certain level of privacy or sanctity associated with them that should be respected? Or are they more like a deck of playing cards that can be freely passed around and used by anyone?
