GB WhatsApp Download is a modified version of the popular messaging app WhatsApp, offering additional features such as enhanced privacy options, customization, and more control over your chats. Users can download GB WhatsApp from third-party sources, as it is not available on official app stores. It allows for features like hiding online status, customizing themes, and using multiple accounts on the same device. However, it's important to note that since it’s not an official app, using GB WhatsApp could potentially compromise your privacy or violate WhatsApp’s terms of service, leading to temporary or permanent bans.
