Given the total global population is around eight billion, its reach is immense. This massive user base necessitates advanced features that go beyond basic text messaging, allowing users to manage complex interactions efficiently within the application. ## Automating Message Expiration Users can manage digital footprints by setting timers for disappearing messages. Options include 24 hours, 7 days, or 90 days after reading. This setting is applied per chat, affecting all participants. It provides a mechanism for temporary communication without deleting the entire conversation history, ensuring sensitive information does not persist indefinitely. ## Securing Sensitive Conversations Privacy is enhanced through the Chat Lock feature, which adds a secondary layer of security to specific threads. By using a PIN or biometric authentication like Face ID, users can hide sensitive chats from unauthorized access. Even if a device is unlocked, these specific conversations remain protected behind the secondary barrier. ## Post-Dispatch Message Editing The platform allows users to modify messages after they have been sent, which is useful for correcting typos. By long-pressing the message and selecting Edit, the content is updated. While an 'Edited' label appears for all participants, the original content remains hidden, maintaining the flow of conversation without requiring follow-up corrections. ## Managing Online Presence Users can restrict who sees their 'last seen' and 'online' status through granular privacy settings. By navigating to the Privacy tab, one can select 'My contacts except' to exclude specific individuals. This provides control over digital availability, allowing users to maintain professional boundaries or personal privacy while still using the application. ## Pinning Critical Information To prevent important details from getting buried in busy group chats, users can pin up to three messages per conversation. These pins can be set to expire after 24 hours, 7 days, or 30 days. This feature is essential for tracking addresses, event times, or other key data points within active threads. ## Customizing Notification Profiles Assigning unique notification sounds and vibration patterns to specific contacts allows for better triage of incoming alerts. By accessing the notification settings within a contact's profile, users can distinguish between urgent messages and those that can be ignored. This customization helps in prioritizing communication without needing to check the device screen. ## Self-Messaging for Productivity WhatsApp supports a self-messaging feature, allowing users to create a chat with themselves. This serves as a convenient space for jotting down quick notes, reminders, or saving voice memos on the go. By searching for their own username or phone number, users can leverage the platform as a personal productivity tool. ## Sources covering this story - https://www.popsci.com/diy/how-to-get-more-out-of-whatsapp-change-how-you-message-tech-tips/ — --- _Summary written by Brifing from the original reporting.
