The green dot on Snapchat indicates that someone is active or online. It stays on until they go offline or stop using the app. Once they become inactive for a while, the green dot will disappear. If you're chatting with someone, the green dot will remain as long as they're actively engaging with the app.
The green dot on Snapchat, known as the "Active Status," appears when a user is online and actively using the app. It disappears shortly after they go inactive. However, Snapchat does not specify an exact duration, but it typically stays for a few minutes after the user exits the app.
