The article addresses the common concern of whether users are alerted when someone takes a screenshot of their conversations on various messaging apps, specifically Instagram, WhatsApp, and Messenger. It outlines that while some platforms do provide notifications for certain types of content, the majority of regular conversations go unnoticed.

On Instagram, users will not be notified if someone takes a screenshot of regular chats, profiles, or stories. Notifications only occur when a screenshot is taken in 'vanish mode' or from content set to view once. Therefore, most daily conversations can be captured without the sender's knowledge.

Similarly, WhatsApp and Messenger do not notify users when screenshots are captured. WhatsApp maintains end-to-end encryption but does not have any screenshot alert feature. The only relevant protection comes from disappearing messages, although again, complete notification on screenshots is not guaranteed. Messenger follows the same principles as Instagram, leaving users unaware when their conversations are screenshot.
