A new study reveals that Instagram and Facebook are the apps that collect the most user data. This is based on an assessment conducted by the website QR Code Generator, which analysed the privacy policies of over 5,000 apps from the Apple App Store. These apps were selected from a broader list of the top 100 apps in each category, with duplicates and those missing data removed.  

To determine which apps are the most invasive, they created an index out of 100 based on 46 indicators including 35 types of data, six purposes for data collection, and five different types of user relationships.

The level of privacy intrusion was measured by whether each data type is tracked and linked, tracked, linked, not linked or tracked, and not collected at all, with “tracked and linked” being the most intrusive. 

Instagram and Facebook come in first place with an index score of 61.47 out of 100. Both apps are among the most widely used worldwide and collect 32 out of 35 data types, 25 of which are linked to the user, while seven are linked and tracked to the user. These apps also rank highly because of how invasive they are in collecting sensitive info like physical addresses, devices, and user IDs. This is in stark contrast with other popular entertainment apps such as YouTube and TikTok, which rank 27^th and 76^th. 

Coming in third is Grab: Taxi Ride, Food Delivery, with a 55.57 out of 100 score. This app collects 27 data types, eight of which are linked to the user, and 15 are linked and tracked. As a ride-hailing and food delivery app, it collects sensitive information such as payment information and other financial data, as well as precise location and purchase history. 

In fourth place, a three-way tie sees Threads, Meta Business Suite, and Messenger, each scoring 54.53 out of 100. These apps collect 32 data types, and while all are linked to the user, none are tracked.  

Further down the list, Nordstrom Rack: Shop Deals ranks seventh with a score of 53.62, collecting 22 data types, four of which are linked to the user, and 18 are both linked and tracked.  

In eighth place, Nordstrom follows closely with a score of 52.54. It collects 22 data types, five linked to the user and 17 linked and tracked. 

Pinterest is in ninth place with an index score of 50.06. This app collects 29 data types, 22 of which are linked to the user and six of which are linked and tracked. 

Rounding out the top ten is AE + Aerie, short for American Eagle Outfitters, the apparel brand, scoring 50.01 out of 100. This app collects 21 data types, three of which are linked to the user and 16 of which are linked and tracked. 

Of all the apps and categories studied, Photo-Video Apps are the most invasive. Although only 23 were over the minimum review threshold and therefore eligible for the study, the category’s overall score is 38.54 out of 100.  

These are followed by Social Networking Apps and Food and Drink Apps. 

Marc Porcar, CEO of QR Code Generator PRO S.L, explains to Digital Journal: “In today’s world, we are incredibly reliant on smartphones, but more specifically, apps – whether we use them for communication, shopping, or transport, they are used on a day-to-day basis.”

porcar adds: “With this in mind, it’s absolutely essential that smartphone users are aware of the level of data collection within the apps that they use daily. Staying informed about the data practices that apps use, maintaining awareness of any privacy policy updates, and taking the time to read and only accept a privacy policy once satisfied are some of the most important steps people can take to remain in control of their privacy.”
