Privacy International: “…Privacy International recently tested the feature to download all ‘Ads and Business’ related information (You can accessed it by Clicking on Settings > Your Facebook Information > Download Your Information). This is meant to tell users which advertisers have been targeting them with ads and under which circumstances. We found that information provided is less than accurate. To put it simply, this tool is not what Facebook claims. The list of advertisers is incomplete and changes over time…

• Despite Facebook claim, “Download Your Information” doesn’t provide users with a list of all advertisers who uploaded a list with their personal data
• As a user this means you can’t exercise your rights under GDPR because you don’t know which companies have uploaded data to Facebook
• Information provided about the advertisers is also very limited (just a name and no contact details), preventing users from effectively exercising their rights
• Recently announced Off-Facebook feature comes with similar issues, giving little insight into how advertisers collect your personal data and how to prevent such data collection..”
