Input Content: Any content you enter in the browser (including search queries, form data) is processed locally, and we will not upload or share this content without your explicit consent.
Sync Services: If the App offers optional cloud sync services (such as bookmark synchronization), this service will be conducted via [Please fill in here: Apple iCloud, or the name of the third-party sync service you use], and we will clearly inform you of the scope and security measures for data synchronization.
