How to prevent my iPhone from being profiled?

Re: “… is it now safe to reinstall them … “

Those apps exist to harvest every possible bit of personal data about you that they possibly can …

… AND then sell that info to those entities who will pay for it.

If you re-install the apps, the harvesting will re-commence.

Delete those apps and their associated data from your phone.

Facebook is built on collecting and tracking all, and Roblox doing similar would not surprise.

A class action lawsuit involving alleged tracking by Roblox is reportedly underway, as well.

Games are going to consume power and generate heat, as well.

And if there’s an add-on VPN app in the mix here, those too involve substantial power consumption and heat generation, and that too for little or no benefit to security.

If Roblox power consumption or heat generation is concerning, check with a Roblox support.

Many iOS apps will track users, too.
