+  #### Sync
+  The synchronization of data is end-to-end encrypted. Safari does not encrypt bookmarks and they are accessible to Apple.

+  #### Extensions
+  We generally do not recommend installing [any extensions](https://www.sentinelone.com/blog/inside-safari-extensions-malware-golden-key-user-data/) as they increase your browser's [attack surface](https://en.wikipedia.org/wiki/Attack_surface); however, if you want content blocking, [AdGuard for Safari](/browsers/#additional-resources) might be useful to you.
