Facebook got itself into a sensitive data scandal when it did shady business with Cambridge Analytica, Instagram confirmed a security issue exposing user accounts and phone numbers, but these apps are basically online security havens compared to TikTok, according to one senior software engineer with about 15 years of professional experience.

2 months ago, Reddit user bangorlol made a comment in a discussion about TikTok. Bangorlol claimed to have successfully reverse-engineered it and shared what he learned about the Chinese video-sharing social networking service. Basically, he strongly recommended that people never use the app again, warning about its intrusive user tracking and other issues. Considering that TikTok was the 4th most popular free iPhone app download in 2019, this is quite alarming.
