 ## Privacy Notes
 
+iOS devices are frequently praised by security experts for their robust data protection and adherence to modern best-practices. However, the restrictiveness of Apple's ecosystem—particularly with their mobile devices—does still hamper privacy in a number of ways.
+
+We generally consider iOS to provide better than average privacy and security protections for most people, compared to stock Android devices from any manufacturer. However, you can achieve even higher standards of privacy with a [custom Android operating system](../android.md) like GrapheneOS, if you want or need to be completely independent of Apple or Google's cloud services.

 ### Activation Lock
 
 All iOS devices must be checked against Apple's Activation Lock servers when they are initially set up or reset, meaning an internet connection is **required** to use an iOS device.

 Therefore, if you use iCloud you should [enable **Advanced Data Protection**](https://support.apple.com/HT212520). This encrypts nearly all of your iCloud data with keys stored on your devices (end-to-end encryption), rather than Apple's servers, so that your iCloud data is secured in the event of a data breach, and otherwise hidden from Apple.
 
+The encryption used by Advanced Data Protection, while strong, [is not *quite* as robust](https://discuss.privacyguides.net/t/apple-advances-user-security-with-powerful-new-data-protections/10778/4) as the encryption offered by other [cloud services](../cloud.md), particularly when it comes to iCloud Drive. While we strongly encourage using Advanced Data Protection if you use iCloud, we would also suggest considering alternatives for most iCloud services, although it is unlikely most people would be impacted by these encryption quirks.
+
 You can also protect your data by limiting what you sync to iCloud in the first place. At the top of the **Settings** app, you'll see your name and profile picture if you are signed in to iCloud. Select that, then **iCloud**, and turn off the switches for any services you don't want to sync to iCloud. You may see third-party apps listed under **Show All** if they sync to iCloud, which you can disable here.
