The recently-added Journal app for iPhones running iOS 17 has been the subject of some scary-sounding claims about potential privacy risks. Fortunately, there's nothing to actually worry about in this instance.
If you've seen any of the Facebook, Instagram or TikTok posts/videos about this setting (which we won't share), they allege that a particular setting, Discoverable by Others, allows anyone nearby to see your name and location. That understandably sounds alarming, but the official explanation of this feature shows that these claims are highly exaggerated.
