The Irish data protection watchdog issued a €225m (£190m) fine and ordered WhatsApp to change its policies.
WhatsApp is appealing against the fine, but is amending its policy documents in Europe and the UK to comply.
However, it insists that nothing about its actual service is changing.
“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 said, announcing the change.
The new policy takes effect immediately.
