Great question! Using incognito mode on your browser helps ensure your local browsing history, cookies, or cache aren’t saved on your device. This offers some extra privacy on your end, especially if you share your computer or want to avoid leaving traces for others who use the same device. However, incognito mode does not hide your activity from your internet provider, Instagram, or the anonymous viewer website itself.
If your goal is to increase privacy while viewing Instagram Stories or highlights anonymously, the best approach is to use third-party services designed for this purpose, such as https://dfviewer.com/. This kind of service allows you to view and download Instagram Stories, highlights, and other content without logging in or revealing your identity to Instagram. Combining incognito mode with a trusted anonymous viewer like dfviewer.com gives you more privacy overall than either method alone.
