The Republic of Ireland's Data Protection Commission (DPC) has levied a €403m (£345m) penalty against Google following a comprehensive review of its data practices.
This decision marks one of the most severe financial sanctions issued by the Irish watchdog authority to date.
The investigation, which began six years ago, was triggered by formal complaints lodged by multiple European consumer rights groups.
Officials focused their scrutiny on three specific functionalities within Google's ecosystem: Web & App Activity, Location History and Location Accuracy.
The period under examination covered the timeframe from 25 May 2018 to 4 February 2020.
Under current regulations, any information capable of revealing a person's whereabouts is classified as location data.
The DPC concluded that Google failed to adequately protect user privacy regarding these specific features during the specified years.
No further details on the implementation of the fine or immediate operational changes have been disclosed by the regulator.
