Interesting study by pCloud, based on the new Apple privacy labels featured in the App Store, which categorises all the information that can be collected on users by apps into 14 categories, and how they're used.
While the worst offenders are no real surprise (Instagram, Facebook, LinkedIn, YouTube) I think Uber Eats deserves a mention as most people do not consider how much data is collected and shared by food delivery apps. DuoLingo, TikTok, Reddit, Snapchat and Spotify are also up there.
On the other end of the scale, tracking and sharing 0% data, I'd like to give an honorable mention to Google Classroom (a bit of a surprise but thankfully also understandable) and Clubhouse. Clubhouse has received attention, including from me, on how they collect phone numbers - and for vague terms of service when it comes to data storage. As of yet they however do not track you or sell your data like many other apps, which is worth noting. It is however new to the game and what the future brings is anyone's guess.
Among some of the safest apps, from a data tracking and sharing perspective, you'll also find Signal (no surprise), Netflix(!), Microsoft Teams, Skype, Telegram, Zoom and Discord.

Thanks to James for alerting me to it.
