← Measured in the wild

app.bestbuy.com

classified as first-party · 2

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

app.bestbuy.com is a subdomain of bestbuy.com, matching the app's own bundle identifier (com.bestbuy.buyphone), so it is almost certainly the developer's own first-party backend rather than a third-party tracker. A first-party API endpoint contact does not by itself imply a data flow beyond the app's core function, and the empty privacy label gives no basis to conclude any specific undisclosed collection, so undisclosed is false.

OpenAI — first-party

The domain app.bestbuy.com appears to be a Best Buy-owned app service domain based on its matching brand domain. No evidence is provided about what data was transmitted, so an undisclosed data flow cannot be determined from this contact alone.

Google Gemini — first-party

The contacted domain app.bestbuy.com matches the app's first-party developer domain (Best Buy). Standard first-party network requests do not automatically indicate undisclosed data collection or third-party sharing.

Think something here is wrong?

Evidence and research improve when people push back. Tell us what to re-check — a misattributed domain, an outdated classification, a claim about your own app — and a human will review it. Responses can take up to 30 days.

If you leave an email it is encrypted at rest and opened only to answer you — never shared, never used for anything else. It is erased 30 days after we resolve this (or 180 days if it is still open) without you asking, and you can erase it sooner at any time; either way your correction stays, anonymously. Leave it blank and your request is fully anonymous from the start (we store no IP address either way).
