evidence: Protecting the privacy of your messages remains the driving force behind what we’re building at WhatsApp. While End-to-end encryption is the foundation to ensure your calls and messages are secure, we continue to add more layers of privacy on top including the recently launched Chat Lock to protect sensitive chats behind a password, Disappearing Messages that vanish, screenshot blocking for View Once, and the ability to keep your online presence private. [...] To spread the word, we’re introducing Privacy Checkup to help make sure everyone knows about the options of protection on WhatsApp. This step-by-step feature guides you through important privacy settings to help you choose the right level of protection, all in one place. Selecting ‘Start checkup’ in your Privacy settings will navigate you through multiple privacy layers that strengthen security of your messages, calls, and personal information.
