The company put out a statement that personal photos remain personal, unless someone screenshots it. They also clarified the time frame for snaps in their server.
Snapchat also says that some information may be delayed in the deletion process as required by law.
If you change your mind about letting them collect information from consented sources, like your phonebook, camera, or location services, you can rescind that permission by changing the settings on your phone.
Other information collected involves internet activity that Snapchat and outside companies may use to better advertise to you. That’s also how Facebook knows where you’ve been shopping online. Same concept.
None of your information is going somewhere you haven’t already given permission for them to use, either through making the information public or by using certain features. If you don’t want the company to have that information, you can change the setting in the app or on your phone.
