Is this mode better on or off?

Enabling incognito mode in Safari on an iPhone does provide some privacy benefits, but it's important to understand its limitations. When you browse the web in incognito mode, Safari doesn't save your browsing history, cookies, or other site data on your device. Additionally, it prevents websites from tracking your activity through cookies and other means.

However, it's crucial to note that incognito mode doesn't offer complete anonymity or hide your browsing activity from the world. While Safari won't save your browsing history locally, your internet service provider (ISP) and the websites you visit can still see your activity. Additionally, if you're connected to a network that employs network-level monitoring or tracking, your browsing activity may still be visible to administrators or network operators.

Moreover, incognito mode doesn't protect against other forms of tracking or monitoring, such as surveillance by government agencies or advanced tracking techniques employed by certain websites or advertisers. It primarily focuses on preventing the information from being stored on your device.

Private browsing or incognito will only prevent sites you visit from showing up in your history or any devices linked to your Apple ID. Your IP address is still visible to sites you visit and does nothing to stop Malware or downloading nefarious files.
