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 — first-party
downdetectorapi.com appears to be the API backend for Downdetector, a service operated under the same corporate umbrella as Ookla's Speedtest (Downdetector was acquired by Ookla in 2018, both now under Ziff Davis), and the Speedtest app surfaces Downdetector outage data, so this looks like a first-party functional endpoint rather than a third-party tracker. Because the record shows no declared collection or sharing at all and I cannot tell from the given data what payload is sent or whether it is linked to the user, I do not assert an undisclosed flow; a human reviewer should confirm the ownership chain and the request contents before publishing.
OpenAI — first-party
The domain appears associated with Downdetector, a service operated by the same company as Speedtest. A domain contact alone does not establish that personal data was collected or shared beyond the app's label.
Google Gemini — first-party
Downdetector is owned by Ookla, the developer of the Speedtest app, making this domain a first-party endpoint. Based on the provided data, there is no evidence of undisclosed data collection or sharing.
