I browse TikTok and Instagram anonymously. Does that mean I'm not using social media?

You're not doing the "social" part of it, but, depending on how you browse, your habit might still be unhealthy, driven by the engagement/addiction algorithms. That's up for you to decide, though, of course.

It means you're not using those sites socially, so you're not using social media, you're just browsing media.
