Ah, welcome, privacy detective! Here’s the scoop, but with a dash of secret sauce: By default, Instagram is like a store with its front windows wide open—strangers can peek in and see your username, profile pic, bio, website link, and your grid of posts and highlights. They can also stroll through your followers/following lists, and watch your public likes and comments do their little dance across public posts.
But here’s a trick for the extra-curious: Want to see exactly what strangers see? Log out of your Instagram account (or open an incognito browser tab), go to your profile, et voilà—instant “stranger goggles” mode! If you’re feeling super-spy, tools like dfviewer.com let you preview your own or others’ profiles as a true outsider. And for extra stealth, remember: stories on public accounts are visible to all unless you flick that “private” switch in your settings—just one tap transforms your open window into a secret garden.
