Incognito mode protects local privacy. Anonymous Instagram viewers protect network privacy. Here's the critical difference - and which you actually need.
True anonymous viewing - not just private browsing. Free to test. No card required.
Visit GoomViewNo. If you sign into Instagram from incognito mode, your username still appears in the viewers list. Incognito only hides activity from people who use your device.
Only partially. You can avoid being tracked by cookies, but if you sign in, Instagram still knows it's you. To be fully anonymous, use an anonymous viewer (which doesn't require sign-in).
For maximum privacy: yes. For practical privacy: just the anonymous viewer is enough.
No. Quiet Mode mutes notifications. It doesn't hide your activity from other users or stop tracking. It's a different feature entirely.
