The decision could have wider European implications.
The regulator, Datatilsynet, had said on 17 July that the company would be fined if it did not address privacy breaches the regulator had identified.
Meta Platforms did not immediately reply to a request for comment.
Datatilsynet had said Meta cannot harvest user data in Norway, such as users’ physical locations, and use it to target advertising at them, called behavioural advertising, a business model common to big tech.
It had until 4 August to prove to the regulator that it had addressed the issue.
