"That's my phone number. People can use that to get into other personal information of mine. And that's just jeopardizing my personal security," explained Daniel Mungal, Snapchat user.
"It's a very real world that we are living in where private information is something hackers really want access to," explained Danielle Hatfield, Owner, Experience Farm.
"Why does my shopping app wants access to my telephone or who I'm texting? And that's a red flag. To me as a user, that's a red flag," explained Hatfield.
"I would very carefully consider whether I would download that app."
With a Snapchat download - you are giving the app access to your test messages, location, and phone calls.
Daniel says he didn't check the privacy settings before installing but will now think twice before adding another app.
"Social media in general gets a lot more information out of you and who knows who they can give it out to," explained Mungal.
Hatfield says, "Once you've downloaded an app, and they have access and your information has been compromised, there really is not much you can do."
Most apps list what information they collect and how it's shared in their privacy policies.
Hatfield says the only way to know you're truly protected is not download any apps.
