How do I make my parents trust me with social media? Example: SnapChat?

I was thirteen when I got snapchat. It comes down to the trust that you have with your parents, as they don't know what you could be snapping to other users. It may come down to a conversation about trusting.

im sorry but i don't think there's a way for that but really in don't blame them. my mom says she trust us with the internet but my brother started looking up dirty things on the internet and she doesn't know! some parents just don't want there child be poisoned by the dirtiness of social media but don't keep your mind on that 24/7. just because your parents don't trust you with the internet doesn't mean they don't trust you with everything.
