FAQ
What is a WhatsApp online notifier?
A tool that alerts you automatically when a number connects or disconnects from WhatsApp, so you do not have to keep opening the chat to look.
How is a notifier different from an online checker?
A checker shows the status at the moment you look. A notifier watches continuously and pings you when the status changes, and keeps a history so you can see patterns.
Does it read messages?
No. It only detects online/offline presence using your own WhatsApp Web session. It never reads chats.
Can I use it on any number?
It works for numbers whose presence is visible to your account. If the person hides their online status in WhatsApp privacy settings, there is nothing to detect.
Responsible use: you track online/offline presence with YOUR WhatsApp session. No message reading, no account hacking. Follow the law. More in Legal.
