The bill means ISPs will record any domain you access and at what time you do so . That means your ISP will know whenever you use Whatsapp so in that specific sense of safe , no , but because everybody uses whatsapp so that fact alone probably doesn ' t mean much . but say for example you and a friend are being monitored for some reason . You send a message to your friend using Whatsapp and within a few minutes they read it . Police or anyone else with access to the data might be able to infer that you and your friend are communicating via Whatsapp because you often use it at the same time . They might then go and get a warrant for more detailed access to your browsing history . The danger here isn ' t about an individual person ' s privacy . The list of agencies above are now capable of studying patterns of behaviour across multiple people without their knowledge . It really is pure surveillance . If you are comfortable with being watched then I suppose you could call it safe . I think the main takeaway from this post is that safe isn ' t the right word to use really . Whatsapp messages themselves are encrypted endtoend , so as far as we know the government can ' t read the messages . GCHQ might have broken the encryption though . It isn ' t public knowledge whether Whatsapp messages are readable .
