One called Private Relay particularly piques the interest of Chinese users living under the country’s censorship system, for it encrypts all browsing history so nobody can track or intercept the data.

When Private Relay is turned on, nobody can track your browsing history — not your internet service provider, anyone standing in the middle of your request between your device and the server you’re requesting information from.

Apple told Reuters that Private Relay won’t be available in China alongside Belarus, Colombia, Egypt, Kazakhstan, Saudi Arabia, South Africa, Turkmenistan, Uganda and the Philippines.

It’s unclear whether Private Relay will simply be excluded from system upgrades for users in China and the other countries where it’s restricted, or it will be blocked by internet providers in those regions.
