How we know this

Counterspy downloads the app from the App Store and statically analyzes its compiled binary. Embedded SDKs are matched against a signature database and resolved to the company that operates each. We also read the developer's App Store privacy label, which lists the data the app says it collects and links to you. We do not run the app or intercept its traffic, so we report capabilities present in the code and the developer's own disclosures, not proven transmission. We assess privacy and data collection, not malware, security flaws, or developer intent. Reports are automated and never edited for payment. Scan v3.37.1, 2026-04-03.

Third-party trackers are advertising, analytics and attribution SDKs detected by static signature matching. Presence shows a capability is compiled in, not that it ran or transmitted data.
"Data the app links to you" is the count of data categories the developer declares as Data Linked To You in its App Store privacy label. Labels are self-reported and not verified by Apple.
Comparison across the 103 travel in our corpus. Trackers: median 5. Data linked to you: median 5.
