In some cases, police can track WhatsApp messages, but it depends on the specific circumstances and the level of encryption used by WhatsApp.

WhatsApp uses end-to-end encryption, which means that messages are only visible to the sender and the recipient. The encryption is so strong that not even WhatsApp can read the messages. However, if the police obtain a search warrant or a court order, they may be able to access WhatsApp messages through the device itself or through backups stored on the device or in the cloud.

Additionally, GBWhatsApp has been known to cooperate with law enforcement agencies in some cases. For example, if a user is suspected of committing a crime and law enforcement officials provide WhatsApp with a valid legal order, WhatsApp may be required to provide the user's account information, including messages.

It's important to note that laws and regulations regarding digital privacy and law enforcement vary by country and region, so the specifics of what police can do and under what circumstances may differ depending on where you are located.
