Instagram shares more personal data than any other app store app, according to a new study.

Secure cloud storage company pCloud examined the new Apple privacy labels on the App Store, analyzing “Date You Will Be Followed”, “Third-Party Advertising” and “Advertising or Marketing to Developers”.

And Instagram has shared 79 percent of the data it collects with third parties. This includes purchases, location, contact information, contacts, user content, search and browsing history, identifiers, usage data, diagnostic and financial information.

In second place is Facebook, which reveals 57 percent of user data, followed by LinkedIn and Uber Eats, both of which give half of user data to third parties.

In fact, grocery delivery apps are surprisingly rich in data: only Just Eat, Grubhub, and My McDonald’s don’t reveal anything at all.

“While apps are sometimes required to share certain information with third parties in order to help them deliver a service, appalling amounts of apps are actually doing it for their own benefit and not for their users,” says Ivan Dimitrov, digital marketing manager at pCloud.

“Benefiting from the exchange of private personal information is becoming more and more common in modern online practice.”

Of course, apps also use the collected data to sell more of their own products. Here, too, Instagram is the worst offender alongside parent company Facebook. Both use 86 percent of the data collected to sell more of their own products.

Klarna and Grubhub are the second worst offenders at 64 percent, while Uber and its food app Uber Eats each consume 57 percent.

Besides Telegram, Clubhouse, Netflix and Signal, Skype, Microsoft Teams and Google Classroom do not collect any data for advertising or third parties. The social media stars Bigo Live and Likke are now among the 20 safest apps that only collect two percent of users’ personal data.

And Amazon was surprisingly low on the list, with minimal tracking for its own advertising and no data shared with anyone.

“Social giants like Instagram and Facebook try to gather as much information as possible about users instead of protecting the privacy of their users,” says Dimitrov. “In the future, everyone who uses apps should be aware of what information they are passing on.”
