I want to make sure my safari data is not being tracked

Hello,

There are a few standard features for protecting our data privacy and an iCloud+ subscription feature as well.

Browse privately in Safari on iPhone - Apple Support

"Control privacy and security settings for Safari

Go to Settings  > Safari, then below Privacy & Security, turn any of the following on or off:

Prevent Cross-Site Tracking: Safari limits third-party cookies and data by default. Turn this option off to allow cross-site tracking.

Hide IP address: Safari automatically protects your IP address from known trackers. For eligible iCloud+ subscribers, your IP address is protected from trackers and websites as you browse in Safari. If this option is off, your IP address isn’t hidden.

Block All Cookies: Turn this option on to prevent websites from adding cookies to your iPhone. (To remove cookies already on iPhone, go to Settings > Safari > Clear History and Website Data.)

Fraudulent Website Warning: Safari displays a warning if you’re visiting a suspected phishing website. Turn this option off if you don’t want to be warned of fraudulent websites.

Privacy Preserving Ad Measurement: This prevents websites from viewing your personal information to serve you targeted ads.

Check for Apple Pay: Websites that use Apple Pay can check to see if you have Apple Pay enabled on your device. Turn this option off to prevent websites from checking if you have Apple Pay.

When you visit a website using Safari that isn’t secure, a warning appears in the Safari search field."

Protect your web browsing with iCloud Private Relay on iPhone - Apple Support

"Protect your web browsing with iCloud Private Relay on iPhone

When you subscribe to iCloud+, you can use iCloud Private Relay to help prevent websites and network providers from creating a detailed profile about you. When iCloud Private Relay is on, the traffic leaving your iPhone is encrypted and sent through two separate internet relays. This prevents websites from seeing your IP address and exact location while preventing network providers from collecting your browsing activity in Safari.

You can turn off iCloud Private Relay at any time. You can turn off the feature completely for iPhone, or just turn it off for a specific Wi-Fi or cellular network."

I hope this helps
