Because Snapchat Stories is designed to display the creator who viewed their story, it is not possible to fully view them anonymously in a guaranteed, legitimate way. Using Airplane Mode after the stories load and then reopening Snapchat is the only "safer" way, but it doesn't always work and can still record a view after you go online. Avoid third-party apps or websites that promise anonymous viewing as they typically breach Snapchat's terms, jeopardize your account, or collect data. The best course of action if privacy is a concern is to avoid viewing the story altogether.
