Alright, I’ve been in a similar situation, wanting to check out a TikTok profile without leaving a trace.
Like others have mentioned, the easiest way is to view the profile while logged out, but that only works if the profile is public. I tried the incognito mode trick DataWanderer suggested, and it worked for basic browsing. Clearing the cache afterward is a good habit.
What I found particularly useful was Zenith Core’s suggestion of using a fresh TikTok install on a separate device with public WiFi. I did this once with an old phone, and it felt much safer than using my main device. Just remember to uninstall the app afterward!
My tip: If you’re really paranoid, create a brand new email address just for the burner TikTok account. This adds another layer of separation from your main online identity.
