WhatsApp is owned by Facebook, now renamed Meta Platforms. With the update, users in Europe will see a banner notification at the top of their chat list that will take them to the new information.
WhatsApp is taking the action after getting hit with a record 225 million euro ($267 million) fine in September from Irelands data privacy watchdog for violating stringent European Union data protection rules on transparency about sharing peoples data with other Facebook companies.
The chat service said it disagreed with the decision, but it has to comply by updating its policy while it appeals. The update doesnt affect how data is handled, and users wont have to agree to anything new or take any other action.
Ireland's Data Privacy Commission is the lead privacy regulator for WhatsApp under European Union rules because its regional headquarters is in Dublin.
A six-hour outage of Facebook services last month highlighted how vital WhatsApp has become for its more than 2 billion users worldwide.
