The majority of privacy and security concerns with Apple products are related to their cloud services, not their hardware or software. When you use Apple services like iCloud, most of your information is stored on their servers and secured with keys which Apple has access to by default. You can check [Apple's documentation](https://support.apple.com/HT202303) for information on which services are end-to-end encrypted. Anything listed as "in transit" or "on server" means it's possible for Apple to access that data without your permission. This level of access has occasionally been abused by law enforcement to get around the fact that your data is otherwise securely encrypted on your device, and of course Apple is vulnerable to data breaches like any other company.

### Encrypted iMessage
|
||||||
|
|
||||||
|
The [color of the message bubble](https://support.apple.com/en-us/104972) in the Messages app indicates whether your messages are E2EE or not. A blue bubble indicates that you're using iMessage with E2EE, while a green bubble indicates the other party is using either the outdated SMS and MMS protocols or RCS. RCS on iOS is **not** E2EE. Currently, the only way to have E2EE in Messages is for both parties to be using iMessage on Apple devices.
|
||||||
|
|
||||||
|
If either you or your messaging partner have iCloud Backup enabled without Advanced Data Protection, the encryption key will be stored on Apple's servers, meaning they can access your messages. Additionally, iMessage's key exchange is not as secure as alternative implementations like Signal's (which allows you to view the recipients key and verify by QR code), so it shouldn't be relied on for particularly sensitive communications.
|
||||||
|
|
||||||
|
### Photo Permissions
|
||||||
|
|
||||||
|
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 the "Select Photos..." option in the permission dialog. You can change photo access permissions at any time by navigating to **Settings** → **Privacy & Security** → **Photos**.
|
||||||
|
|
||||||
|
![Photo Permissions](../assets/img/ios/photo-permissions-light.png#only-light) ![Photo Permissions](../assets/img/ios/photo-permissions-dark.png#only-dark)
|
||||||
|
|
||||||
|
**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.
|
||||||
|
|
||||||
|
![Private Access](../assets/img/ios/private-access-light.png#only-light) ![Private Access](../assets/img/ios/private-access-dark.png#only-dark)
|
||||||
|
|
||||||
|
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. You can lock an app by long-pressing 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-pressing 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 editing tools to do so.
|
||||||
|
|
||||||
|
- Open the **Photos** app and tap the photo you have selected for redaction
|
||||||
|
- Tap the :material-tune: (at the bottom of the screen) → markup symbol (top right) → plus icon at the bottom right
|
||||||
|
- Select **Add Shape** and choose the square or circle
|
||||||
|
- On the toolbar, tap the circle (left-most option) and choose black as the color for filling in the shape. You can also move the shape and increase its size as you see fit.
|
||||||
|
|
||||||
|
**Don't** use the highlighter to obfuscate information, as its opacity is not quite 100%.
|
||||||
|

Jailbreaking an iPhone undermines its security and makes you vulnerable. Running untrusted, third-party software could cause your device to be infected with malware.

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%.

If your threat model includes forensic tools, and you want to minimize the chance of exploits being used to access your phone, you should restart your device frequently. The state *after* a reboot but *before* unlocking your device is referred to as "Before First Unlock" (BFU), and when your device is in that state it makes it [significantly more difficult](https://belkasoft.com/checkm8_glossary) for forensic tools to exploit vulnerabilities to access your data. This BFU state allows you to receive notifications for calls, texts, and alarms, but most of the data on your device is still encrypted and inaccessible. This can be impractical, so consider whether these trade-offs make sense for your situation.
