iOS Review


TikTok is one of the most downloaded of all time and is exploding in usage amongst children and young adults - but it still connects users to privacy-invasive tech giants like Google and Facebook. Not only that, but it connects to trackers Branch and AppsFlyer even before the app is opened for the first time.

Update 07/08/2020: TikTok was recently discovered to be secretly and constantly accessing the contents of the clipboard. As a result of this, we've downgraded them from a C to a D, and have also added checking for clipboard access to all our Privacy Reviews from now on.

TikTok's Privacy Rating is D. We found 4 different third-party trackers in the TikTok app, and there were 109 attempted tracking connections detected during our test.

Testing Results

Blocked tracking attempts.

How was tracker testing done?

Tested using Lockdown v0.3.8

What was done during the test?

109 attempts in 3 minutes of using the app: Installation, launch, email signup, and sharing one three-second video.

How many tracking attempts each time the app is opened?

25 tracking attempts each time the app is relaunched.

Did user give consent to tracking before tracking started?

No. Tracking begins immediately upon app install completion, *even before* the app is launched. Connections are made before app launch to AppsFlyer and Branch trackers by abusing an Apple iOS feature intended originally for Password Autofill.
