This page aggregates measured, corroborated evidence: donors' iPhones recorded apps contacting this domain, every claim below was reported by separate accepted donations and published under a human verdict (later rows for an approved app inherit its verdict). A contact is a measurement, not an accusation — it does not show what data was sent.

What our research panel found AI-drafted · human-reviewed
We ask several independent AI models the same question and publish their answers separately — cross-vendor agreement is evidence against fabrication, and disagreement is worth seeing. 3 of 3 models answered, overall confidence high. A human reviewed this domain's claims before anything here published.
Anthropic Claude — cdn
tiktokcdn.com is TikTok's own content delivery domain (the 'sf16-sg' prefix suggests a Singapore-region static file host), so this is first-party CDN infrastructure operated by the app publisher. Content delivery to the app's own CDN implies no data flow beyond the extensive collection TikTok already declares, so nothing appears undisclosed here.
OpenAI — cdn
The tiktokcdn.com hostname appears to be a TikTok content-delivery domain, likely used to serve app media or static resources. The extensive declared collection label covers relevant app-content and device data categories, and the hostname alone does not establish an undeclared data flow.
Google Gemini — cdn
The domain sf16-sg.tiktokcdn.com is a first-party content delivery network domain used by TikTok to deliver app content and media assets. This standard asset delivery function does not indicate an undisclosed data collection flow.
