Chat Locker is an Android application developed by Splintel that aims to provide users with a secure way to protect their private and group WhatsApp conversations. By adding a passcode, this app ensures that only authorized users can access the chats.

With Chat Locker, you can easily maintain the privacy of your WhatsApp messages. The app allows you to hide your personal chats from prying eyes, giving you peace of mind knowing that your conversations are safe and secure.

One of the key features of Chat Locker is its accessibility permission API. This allows the app to monitor the opening and closing of chats on WhatsApp Messenger, as well as lock and unlock specific chats. It's important to note that this permission does not grant access to read or view your chats.

If you're looking for a reliable and convenient way to protect your WhatsApp conversations, Chat Locker is a great option. It's free to use and offers a simple and effective solution for safeguarding your private messages.
