TikTok has access to your camera and microphone, and facial recognition and voiceprinting are considered biometric information.

You can block the permission in settings, but as explained in the FCC letter, TikTok has a documented pattern of bypassing system permissions and accessing data that they shouldn't actually be able to access (which is malware-like behavior).

If TikTok can actually access the camera and microphone after permission has been denied, then Apple and Google have a much bigger issue on their hands and need to fix that ASAP.

Read the letter. It's talking about past issues. Yes, security exploits are a problem for the platform, but that's no excuse for apps to exploit them maliciously, against the user's knowledge or wishes.

They could produce some very high-quality facial recognition data, thats biometric as well

that's fair, I denied the app permission to access my camera since I just watch videos on it

it would be really helpful for the FCC to explain to content creators why and how their biometric information can be used against them, tiktok is just one of the companies scanning their faces in that regard
