The €225m (£190m) fine is the second largest in history over GDPR.
The tech giant is appealing against the penalty but must still update its privacy policies for Europe and the UK in the meanwhile, with immediate effect, according to the BBC, which first reported the news.
“There are no changes to our processes or contractual agreements with users, and users will not be required to agree to anything or to take any action in order to continue using WhatsApp,” the company told the BBC.
The news comes after Meta, the owner of WhatsApp and Facebook, announced that encrypted messaging will not be completely rolled out until some point in 2023, following fears such a move could put children at greater risk of exploitation and abuse.
Meta said it is taking time to “get this right” and pledged to work to strike a balance between privacy and safety online.
