Can I trust myGMC?
This app did not meet two or more trust checks, has a critical issue in one, or has a red flag.
- Avoid if
- Drivers who prefer no insurance-affiliate analytics
- What it means for you
- The build includes code to send usage and session activity to Heap (ContentSquare), Adobe Experience Platform, and Salesforce for analytics and marketing. The binary links the Arity SDK, an Allstate subsidiary that specializes in driving behavior analysis. In some areas, user data may not be fully protected.
- Main concern
- Production Azure APIM client secret hardcoded, enabling unauthenticated API access
- The developer's description
- MyGMC is General Motors' mobile app for vehicle owners, enabling remote vehicle control (start/stop, locking), real-time location tracking, charging management, diagnostics access, and geofence-based alerts for GMC vehicles.

Trust checks
Secure by Design
An item rated high or above is openSecurity 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 evidence was found of proprietary data formats that trap the user's data, artificial barriers to account cancellation, or mechanisms designed to make it unreasonably difficult to stop using the service. The app follows standard account-based automotive app practices.
Strengths
- Firebase Analytics is explicitly disabled across all environments — the SDK is present only for push notifications, not behavioral data collection
- Login credentials and OAuth tokens are stored in the iOS Keychain with the strongest protection class, including biometric binding that prevents extraction even on a compromised device
- Certificate pinning is active on all ten GM core API domains, protecting vehicle API traffic against network interception
- No memory safety vulnerabilities were found in the compiled native binary by automated static analysis
- Datadog performance monitoring does not include session replay in this build, limiting the performance data the build includes code to send
- AppsFlyer attribution is gated behind ATT consent — advertising identifiers are collected only when the user explicitly grants permission
- Cross-app credential sharing is restricted exclusively to GM's own four brand apps under a single Apple Developer Team ID — no third-party infrastructure can access these shared credentials
