Is it possible to identify users using an iPhone while they are utilizing "Private Browsing" mode?

Looking for a solution to detect private browsing mode in my jquerymobile App. I need localStorage and sessionstorage to work properly, but prompting users to enable cookies when private browsing is enabled doesn't solve the issue. Is there a way to test if the user has private browsing enabled?

Any help would be appreciated. Thanks!

Answer №1

While I haven't had the opportunity to test this function on an iPhone, it has been successfully tested in desktop Safari browser (in private mode). The code below effectively catches and handles errors as expected.

function checkStorageAvailability() {
    try {
        localStorage.setItem("__test", "data");
    } catch (error) {
        if (/QUOTA_?EXCEEDED/i.test(error.name)) {
            return false;
        }
    }
    return true;
}

if (!checkStorageAvailability()) alert('localStorage is not enabled');
