The European Consumer Organisation, an umbrella consumer lobbying group, alleges that Google grabs people's data mostly through "location history" and "web and app activity," using "various tricks and practices" to make sure those features are kept enabled.

The group (known also as BEUC, the abbreviation of its name in French) says consumers aren't informed about how their personal data is used, nor does it offer them a real choice about providing it.
"Google's data hunger is notorious but the scale with which it deceives its users to track and monetise their every move is breathtaking," said Monique Goyens, BEUC's director general, in a release.
"The situation is more than alarming. Smartphones are being used for spying on our every move. This is not the digital society that European consumers want to live in."
"Location History is turned off by default, and you can edit, delete, or pause it at any time. If it's on, it helps improve services like predicted traffic on your commute," a Google spokesperson said in a emailed statement.
