About unsupported apps
Unsupported apps are altered versions of WhatsApp, which means they’re developed by third-parties and violate our Terms of Service. WhatsApp doesn't support these third-party apps because we can't validate their security practices.
Unsupported applications put your privacy, security, and safety at risk. They aren’t associated with WhatsApp and as such aren’t subject to our security measures. There are significant risks associated with using unofficial apps to send personal messages and data such as your location, as well as receiving files or links.
Some accounts might be temporarily or permanently banned if you’re using an unsupported version of WhatsApp instead of the official WhatsApp app. You can learn more in this article.
How to switch to the official WhatsApp app
We recommend saving your chat history before downloading our official app. Learn how to save your chat history on Android or iPhone. Please note that we can't guarantee that the chat history transfer will be successful because WhatsApp doesn't support unofficial apps.
