The online instructions for restricting data access are very complex and confusing, and the steps required are scattered in different places. There’s no clear direction on whether to go to the app settings, the central settings – or even both,’ says Amel Bourdoucen, a doctoral researcher at Aalto.

`I’m curious to know in what way are the instructions confusing. I do wish iOS was better about settings but in general app specific setting will be mostly in the actual app. System wide settings or app settings that modify a system setting for that app will be available in the Settings app.

It turned out that the participants weren’t able to prevent any of the apps from sharing their data with other applications or the service provider.

Yeah I’m curious to know what the researchers are referring to. Is it the tracking features?

Finding and adjusting privacy settings also took a lot of time. ‘When making adjustments, users don’t get feedback on whether they’ve succeeded. They then get lost along the way, go backwards in the process and scroll randomly, not knowing if they’ve done enough,’ Bourdoucen says.

Settings app > Privacy and Security takes a lot of time?

This article is pretty vague and doesn’t really offer any good feedback. The author doesn’t mention which specific setting they are having trouble limiting. Apple is not perfect but out of all the big tech, they’re the most privacy sound. I can’t imagine it’s any better with Googles Android or Windows.
