This means TikTok can use your face, voice, creative work, and personal data inputs to build commercial AI products, with no obligation to compensate you and no ability for you to revoke that permission after the fact.
TikTok's Terms grant the platform a permanent, irrevocable, royalty-free license to use all content you post — including videos, messages, and AI prompts — to train machine learning models and develop new technologies, meaning you cannot revoke this right even if you delete your account or content. Users are also bound by a mandatory arbitration clause with a class action waiver, which means you cannot sue TikTok as part of a group if you believe your rights have been violated. You can delete your account and content via the in-app settings, but note that content already incorporated into other users' posts will remain publicly accessible.
