Download Snapchat w/o parents permission?

My parents aren't letting me use Snapchat. All of my friends have it, I hear everyday about how I should get it but I can't without my parents' permission and they won't let me have any social media.

My parents are both overly strict, they don't want me to have a phone until I'm eighteen and they would stop me from getting one after that if they could. They just want the best for me but they can't understand that I need Snapchat. They went to school before social media existed so they don't know what it's like. Is there any way I can get it without their permission?
