ANYCHAT is a free Android application developed by techquich in the Social & Communication category. It allows you to chat directly with any unknown or unsaved number on WhatsApp without adding it to your contacts. The app supports both WhatsApp and WhatsApp Business, and you can chat with people from multiple countries without any sensitive or harmful permission.

To use ANYCHAT, you need to install WhatsApp or WhatsApp Business first. Then, select the country code of the unknown/unsaved number you want to chat with and enter the phone number. Simply click on the message button, and the chat window will open up for the unknown/unsaved number.

The app is safe to use as it does not send or store any unknown/unsaved numbers on any server. Instead, ANYCHAT uses WhatsApp's 'click to chat' feature to open a chat with any number. Therefore, there is no need to add the number to your contacts list.

Please note that ANYCHAT or its developer is not affiliated with WhatsApp, and you should follow WhatsApp's terms and conditions while sending messages through ANYCHAT.
