WhatsApp goes on to further explain the policy updates in detail via the legal page on its official website. One of the biggest changes to data collection is the storage of media on the company’s servers (in encrypted form) to aid efficient forwarding. Yeah, if you don’t already know, WhatsApp can now keep track of forwards and even give you the option to search the web when it thinks a message or media has been forwarded too many times.
So yeah, there’s nothing major that you need to worry about, and can continue using WhatsApp like you already did. The company has simply offered insight into the data collection processes after the rollout of new features, integrations, and more over the previous year.
