Snapchat is a mobile messaging application known for its ephemeral content, primarily governed by its terms of service and privacy policy. Users must be over 13 and by agreeing to the terms, they grant Snapchat a broad, royalty-free license to their content while retaining responsibility for what they upload. The company collects various user data including location, usage, device information, and may share this data with affiliates, advertisers, and for legal reasons.
