This provision authorizes construction of cross-device activity profiles and demographic inference from behavioral data, which informs ad targeting on TikTok and through the TikTok Ad Network on third-party platforms. The inferred data may include attributes not directly provided by the user.
⚠ Cross-device activity tracking and demographic inference will continue under the terms as written unless managed through in-app Ads settings

"We automatically assign device IDs and user IDs, and may use this and other information to identify your activity across devices. [...] To infer additional information about you, such as your age, gender, and interests.Excerpt from TikTok's Privacy Policy
(1) REGULATORY LANDSCAPE: Cross-device tracking and demographic inference from behavioral data engage CCPA provisions on profiling, sensitive personal information, and opt-out rights for targeted advertising. The policy states TikTok does not engage in profiling resulting in legal or similarly significant effects as defined under applicable law, but cross-device ad targeting inference is a distinct category. FTC oversight of cross-context behavioral advertising practices is relevant. (2) GOVERNANCE EXPOSURE: Medium. The combination of cross-device tracking and demographic inference creates a behavioral profile that may qualify as sensitive data processing or profiling under applicable state privacy laws, particularly where inferred attributes include health, identity, or financial indicators. (3) JURISDICTION FLAGS: California CCPA and the California Privacy Rights Act provide opt-out rights for cross-context behavioral advertising. Colorado, Connecticut, Virginia, and Texas privacy laws include opt-out rights for targeted advertising based on profiling that users may be entitled to exercise. (4) CONTRACT AND VENDOR IMPLICATIONS: Advertisers using TikTok Pixel or other TikTok Advertiser Tools should assess whether cross-device data flows from their properties to TikTok trigger data processing agreement obligations or joint controller considerations under applicable law. (5) COMPLIANCE CONSIDERATIONS: Users in states with targeted advertising opt-out rights should be provided accessible opt-out mechanisms. The policy directs users to in-app Ads settings and a webform for non-account holders. Compliance teams should verify that these mechanisms operationally satisfy state-specific opt-out requirements.
