Can I trust United Airlines?
This app did not meet two or more trust checks, has a critical issue in one, or has a red flag.
- What it means for you
- Analytics and advertising SDKs from Google, Kochava, Quantum Metric, Mixpanel, and Snowplow are bundled in the build alongside core trip features. Location access requires a current trip context and an explicit permission grant from the user. Account credentials and reservation details are protected by device-level encryption.
- Main concern
- Boarding passes, MileagePlus PIN, and PII stored unencrypted in on-device database
- The developer's description
- Complete travel companion for United Airlines. Book flights, check in, manage boarding passes, track luggage, earn MileagePlus miles, access inflight entertainment and Wi-Fi, plus 24/7 customer support.

Trust checks
Secure by Design
Items recorded, result pending reviewSecurity gaps detected
Why this result
This check looks for security issues at high severity or above in the code of this build, and at least one was recorded. Issues of this kind include a credential or token another app on the device can reach, sensitive data stored without protection, and network paths that expose information in transit.
Data Minimization
One criterion not metTracking lacks clear disclosure
Why this result
This build contains analytics or attribution code written to send data to companies other than the developer. No consent step was found before that code runs, and the app's disclosures do not describe the collection in full. Tracking by itself is ordinary; what this check reports is the combination of collection, recipient and absent disclosure.
Manifest Mismatch
One criterion not metDisclosure incomplete or contradicted
Why this result
The check compares the app's privacy disclosures against what the code does, and at least one claim did not match in this build. Mismatches of this kind include a data category collected but not disclosed, a recipient the disclosure omits, and an identifier attached to data the disclosure describes as anonymous.
User Control
StrongNo lock-in
Why this result
The check looks for a way to export the data an account has accumulated and a way to delete the account itself. In this build, either both were found, or the app has no account of its own and keeps its data on the device. For an app without an account, the developer has no server-side copy to export or delete, and deleting the app removes the data in its own storage.
No artificial barriers to leaving the service were found in the app code. No proprietary local data formats that would trap user content were identified. The app connects to United's servers for booking and loyalty account functions, standard online service behavior, and no obstacles to account management were observed.
Strengths
- Login sessions, account data, flight status, and bag tracking protected with Android Keystore-backed AES-256-GCM encryption across multiple modules
- ADB backup disabled prevents app data extraction from non-rooted devices
- Background location collection gated on remote feature flag, explicit OS permission grant, and active trip eligibility — not collected passively
- WebView SSL errors correctly rejected by default with no handler.proceed() bypass found anywhere in the codebase
