Brave on iOS allows you to configure your default Shields settings and manage other private data the same way you can on Desktop and Android. You can find more information on Brave Shields here. 

Brave Shields & Privacy

You can find Shields and Privacy settings on the iOS application:

1. In Brave, tap Menu --> All Settings --> Shields & Privacy.
   Alternatively, you can click on the Brave Shields icon and navigate to Change Shields Global Defaults.

Brave Shields Global Defaults

The top section in Brave Shields & Privacy are the default protections that Shields will use when visiting websites. The default settings are optimized for user protection and minimal conflicts. These settings can be adjusted to meet individual needs.

Note: Changing these settings won't affect your existing per-site settings. 

Clear Private Data

You can clear browser data such as Browsing History, Cookies and more. Choose the data types you would like to remove, then tap Clear Data Now. This action cannot be reversed.

Other Privacy Settings

The last section contains additional privacy and security settings which can be customized based on user preferences.

• Private Browsing Only
  Toggling this option On will tell the browser to only open private windows when the browser is launched. The browser will behave this way until the setting is toggled Off. Please see our Private Browsing section for more information on what Private windows are and how they function.
• Block `Switch to App` Notices
  Enabling this setting will prevent the "open-in-app" notices from appearing. You can learn more about Switch to App prompts here. 
• Allow universal links to open in external apps
  Enabling this option will open links in external apps when applicable.
• Block Popups
  This option is set to On by default. This prevents websites from opening new browser windows/tabs without your permission. We recommend keeping this option On.
• Block Dangerous Wesites
  This option is set to On by default. This protection will reference the Google Safe browsing service (note that these connections are always proxied so that your personal/system information is never sent to Google directly) which is used to track, flag and warn a user when sites are known to be potentially malicious or harmful. We recommend keeping this option On.
