Discount Tire
Reinalt-Thomas Corporation · Build 3.10.7
Static checks identify review items, not a guarantee of safety.
Backend checks: 2 unauthenticated read checks against backends referenced in this build — 2 refused access. Each check describes one request at the recorded scan time and does not establish the backend's current state.
Overview
4 finding categories to review
Discount Tire (com.gpshopper.discounttire) scored grade B, 91 out of 100, in a static scan of version 3.10.7 on 2026-11-03. It has no high or critical findings, and 4 lower-severity finding categories across 5 occurrences. 2 tracking SDKs are present in the package, which describes what ships, not what runs or what it sends. This is static analysis of a single build: it does not observe the app running and does not establish that any data is exposed.
Start with these findings
mediumShort signing key (RSA 1024-bit)1 occurrence
Interpretation & review guidance
The signing key is shorter than the modern 2048-bit RSA minimum. Short keys are cryptographically weaker; a release should re-key to at least RSA-2048 (or an EC key).

- Evidence
- 1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- Static detection; current reachability is not established.
lowBackground location access with advertising SDKs present1 occurrence
Interpretation & review guidance
The app can access location in the background (even when closed) and also ships advertising/attribution SDKs. Background location is a heightened-scrutiny area for Google Play and privacy regulators; confirm it is essential and disclosed, and that location isn't shared with ad networks.

lowFirebase Storage bucket reference1 occurrence
Interpretation & review guidance
A Firebase Cloud Storage bucket reference (the default <project>.appspot.com). Storing user files here is normal — it's only an exposure if the Storage security rules allow public read/list, which live verification tests.

lowGoogle API key (client-shipped; restriction unverified)2 occurrences
Interpretation & review guidance
Android apps are designed to ship Google API keys in the client; Google restricts them by app signing certificate + enabled API. This is only a problem if the key is left unrestricted — presence alone is expected, not an exposure.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Background location Precise location Approx. location
Requested permission inventory (15)
Data collection & flow (privacy signal, not part of the grade)
- Approximate location, Precise location, Background location requested while 1 ad/attribution SDK(s) are present (Google AdMob) — location commonly feeds ad targeting.
- Persistent-identifier APIs referenced in code (Android ID, Device ID / IMEI, Hardware MAC address) with 2 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
This maps what the app can access (permissions it requests, identifier APIs its code references) to the third parties bundled in it. It reflects capability and SDK presence — not proof that a specific value was transmitted.

The badge reads the latest recorded grade each time it is loaded, and links back to the full report so a reader can see the build it covers and what the scan could not see.
Grades can move when a new version is scanned or when a detector is corrected. If you would rather publish a grade that cannot change under you, link a signed Proof Capsule instead.
API users can request authenticated, scan-specific exports at /v1/scans/c82751b6-5c6a-40ee-aad6-1b6a64b48300/findings.sarif (also coverage.json and proof.json).
