Web Storage (sessionStorage and localStorage) in private browsing mode (incognito)

Question

BACKGROUND

The HTML5 Web Storage feature in modern browsers is accessed through Javascript commands such as:

sessionStorage.setItem("username", "John");
localStorage.setItem("username", "John")

The site Can I use indicates that browser support is near 90%. However, in the "Known Issues" tab, Can I use says:

In private browsing mode, Safari, iOS Safari and the Android browsers do not support setting localStorage.

MY QUESTION

In private browsing mode, do Safari, iOS Safari and the Android browsers still support sessionStorage?

I was looking for an official answer not just a test of one browser. This is unfortunate since sessionStorage, as the name implies, should be allowed in private browsing mode. – Chellman

It's disabled with some settings in some browsers. A great work-around available in this question: #35608224 See also: #21159801 – Boyle

Its 2017 now , has anything changed in regards to private browsing mode (incognito) ? – Intellectualize

Answer 1

Android and chrome I believe allow you to access old keys in session storage, but not write to it. I know that Safari will not allow any use of session or local storage.
