Next is advertising. Apple Advertising is more focused on privacy than other platforms, blocking ads from tracking you across websites and services. You can turn off the Personalized Ads toggle. You’ll still get ads, but they’ll be generic. If you turn on Apple Advertising, you can tap into the Ad Targeting Information screen to see what data is shared, such as your birth year, zip code, and the categories for apps you have downloaded.
Generate Privacy Reports
This isn’t really a setting, but the iPhone has built-in privacy reporting tools that can give you insight into what data apps are requesting and using. In the Privacy & Security menu, near the bottom, you’ll see the App Privacy Report and Apple Intelligence Report.
For the former, you’ll see the domains the app contacts each time you use it, as well as a layout of how many domains an app contacts. For Apple Intelligence, you’ll see private compute requests and what data was shared with the request. This report is exported as a JSON file, and you’ll need a text editor to view it. Regardless, both of these reports are fairly technical, and they don’t help your privacy; they just give you more information.

Keep Notes Local
Apple automatically stores and syncs anything you put in the Notes app through iCloud, so no, those random thoughts you jotted down five years ago aren’t completely private. Thankfully, you can keep them private with an “On My iPhone” account, which, as the name suggests, doesn’t sync your notes and keeps them local to your device.
To set it up, open Settings and go down to the bottom of the list for Apps. Find the Notes app and toggle the On My iPhone Account setting on. Just above it, you can also set a password if you want to encrypt and lock any highly sensitive notes. Remember, you won't be able to pull up these notes on another Apple device because they won't sync, and if you lose your iPhone, you may not be able to access your notes altogether without a recent backup.
Hide (or Lock) Apps and Photos
You can hold down on any app icon, select Edit Home Screen, and tap an app to hide it. That’ll keep the app on your phone, but it won’t appear on your home screen. (You can search for it via Spotlight.) You can also hold down and select Require Face ID to lock the app, meaning it'll require biometric authorization every time you open the app.
