How Private Is Samsung Internet’s Secret Mode, Really?

Samsung Internet Secret mode reduces browsing traces saved on your phone, but it does not make your online activity anonymous.

Samsung Internet’s Secret mode helps keep browsing history, cookies, and search records from being saved in the browser’s usual local history. It is not anonymous browsing: Samsung warns that websites, your internet service provider, apps, and the phone manufacturer may still see activity and data. Think of it as a way to reduce traces left in the browser on your phone—not a way to disappear online.

What Secret mode keeps off your phone’s usual browser history

Samsung says Secret mode does not save browsing history, cookies, or search records in the normal browser history. Samsung’s developer documentation also describes history, cookies, cache, saved login data, and autofill data as browsing data that is not left behind in the usual way.

Samsung says cookies and browsing history from Secret mode are erased from the phone once all Secret mode tabs are closed. That is the stated cleanup point; simply switching away from a tab is not the same as closing every Secret mode tab. Samsung Canada’s support guide describes this behavior.

Who may still see your activity

Secret mode does not prevent websites or network-side services from observing visits. Samsung’s US support guide warns: “Your activity and data may still be visible to websites, your internet service provider, apps, and phone manufacturer.” Secret mode therefore addresses what the browser keeps locally, not what every other party can observe or collect. Samsung’s US guide covers these limits.

What can remain saved in Secret mode

Secret mode is not a promise that nothing can be saved. Samsung says users can save pages and bookmarks in a separate Secret mode area, where those items are visible only in Secret mode. Its developer documentation describes saved pages and bookmarks as kept separately with encryption and user authentication. This description concerns those saved items; it should not be read as a claim that all browsing activity is encrypted or hidden from the network. Samsung Developer documentation explains the separate storage.

How Secret mode settings affect privacy

Samsung’s US guide lists controls for using a password, allowing screenshots, staying in Secret mode after closing the browser, configuring Smart anti-tracking, and resetting Secret mode. These settings can change access to Secret mode or how the browser behaves, but they do not make browsing anonymous to websites or network providers.

When Secret mode is useful

Use it when you want to reduce ordinary history and cookie traces left in Samsung Internet on the phone, especially on a device you share. Close all Secret mode tabs when finished to trigger Samsung’s stated cleanup of cookies and browsing history. Do not rely on it to hide a visit from a website, your ISP, apps, or the device manufacturer.
