iOS Review


Shein is a "fast-fashion" app that has been exploding in popularity. It uses many "tech-giant" trackers, but also uses some trackers ("Scarab Research") that we could not find any information on, which is pretty sketchy.

Shein's Privacy Rating is C. We found 6 different third-party trackers in the Shein app, and there were 208 attempted tracking connections detected during our test.

Testing Results

How was tracker testing done?

How many tracking attempts each time the app is opened?


Did user give consent to tracking before tracking started?

No, tracking begins during app installation and after app launch, before any consent is given.
