To take full advantage of the private browsing feature, users need to close their sessions frequently.

What you can do with private browsing

  • This prevents other people using the same device from knowing your search history, input information, browsing history, etc. (hereinafter collectively referred to as "history and input information") and from taking over your login status to the website.

What you cannot do with private browsing

  • The content that you downloaded will not be deleted.
  • If you are using the network provided by the site operator, Internet service provider, workplace, school, etc., you will not be able to prevent your History and Input Information from being tracked by the administrator.
  • Private browsing is not a feature that blocks ad personalization based on your action history (browsing history, etc.). If you wish to turn off the ad personalization feature, you can do so by turning it off from "Ad settings(Japanese only)" However, please note that this setting is executed by maintaining the settings information in the "device's storage area allocated to each site" explained above, so if you wish to continuously turn off the ad personalization feature, you would need to turn off the setting when you are in the normal browsing mode as well as for each private browsing session.

*3 "Private browsing" is also called "Private Browse," "InPrivate Browsing," etc., depending on the browser used. The private browsing function is provided by each company's browser, and we do not guarantee its functionality.
