 When an app prompts you for access to your device's photo library, iOS provides you with options to limit what an app can access.
 
-Rather than allow an app to access all the photos on your device, you can allow it to only access whichever photos you choose by tapping on the "Select Photos..." option in the permission dialog. You can change photo access permissions at any time by navigating to **Settings** → **Privacy & Security** → **Photos**.

 **Add Photos Only** is a permission that only gives an app the ability to download photos to the photo library. Not all apps which request photo library access provide this option.

 Some apps also support **Private Access**, which functions similarly to the **Limited Access** permission. However, photos shared to apps using Private Access include their location by default. We recommend unchecking this setting if you do not [remove photo metadata](../data-redaction.md) beforehand.
 
 ### Contact Permissions
 
 Similarly, rather than allow an app to access all the contacts saved on your device, you can allow it to only access whichever contacts you choose. You can change contact access permissions at any time by navigating to **Settings** → **Privacy & Security** → **Contacts**.

 ### Require Biometrics and Hide Apps
 
-iOS offers the ability to lock most apps behind Touch ID/Face ID or your passcode, which can be useful for protecting sensitive content in apps which do not provide the option themselves. This can be done by long tapping on an app and selecting **Require Face ID/Touch ID**. Apps locked in this way require biometric authentication whenever opening it or accessing its contents in other apps. Also, notification previews for locked apps will not be shown.
+iOS offers the ability to lock most apps behind Touch ID/Face ID or your passcode, which can be useful for protecting sensitive content in apps which do not provide the option themselves. You can lock an app by long tapping on it and selecting **Require Face ID/Touch ID**. Any app locked in this way requires biometric authentication whenever opening it or accessing its contents in other apps. Also, notification previews for locked apps will not be shown.
 
 In addition to locking apps behind biometrics, you can also hide apps so that they don't appear on the Home Screen, App Library, the app list in **Settings**, etc. While hiding apps may be useful in situations where you have to hand your unlocked phone to someone else, the concealment provided by the feature is not absolute, as a hidden app is still visible in some places such as the battery usage list. Moreover, one notable tradeoff of hiding an app is that you will not receive any of its notifications.
 
 You can hide an app by long tapping on it and selecting **Require Face ID/Touch ID** → **Hide and Require Face ID/Touch ID**. Note that pre-installed Apple apps, as well as the default web browser and email app, cannot be hidden. Hidden apps reside in a **Hidden** folder at the bottom of the App Library, which can be unlocked using biometrics. This folder appears in the App Library whether you hid any apps or not, which provides you a degree of plausible deniability.
 
 ### Blacking Out Faces/Information
 
-If you need to hide information in a photo, you can use Apple's built-in tools to do so. Open the photo you want to edit, press edit in the top right corner of the screen, then press the markup symbol at the top right. Press the plus at the bottom right of the screen, then press the rectangle icon. Now, you can place a rectangle anywhere on the image. Make sure to press the shape icon at the bottom left and select the filled-in rectangle. **Don't** use the highlighter to obfuscate information, because its opacity is not quite 100%.
