Zeel Walls - 4K Wallpapers
YoG · Build 43.0.0
Static checks identify review items, not a guarantee of safety.
Overview
2 high or critical finding categories to review
Zeel Walls - 4K Wallpapers (app.yog.zeelwalls) scored grade F, 0 out of 100, in a static scan of version 43.0.0 on 2026-10-10. It has 2 high or critical findings among 5 finding categories across 6 occurrences. 2 findings were confirmed live: an anonymous request reached a backend the app references and it answered without authentication. No credential was used and no stored data was read. 8 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
criticalFirebase Realtime Database reference — confirmed publicly readable1 occurrence
Interpretation & review guidance
A Firebase Realtime Database URL. Nearly every app that uses Firebase ships one. It's only an exposure if the database rules are world-readable — that's what live verification checks.
- Evidence
- 1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- 1 historically verified occurrence at the recorded scan time. Current reachability is not established.
criticalFirebase Storage bucket reference — confirmed publicly readable2 occurrences
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.
- Evidence
- 2 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- 2 historically verified occurrences at the recorded scan time. Current reachability is not established.
lowGoogle API key (client-shipped; restriction unverified)1 occurrence
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.
- 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.

lowSupabase anon key (public client key)1 occurrence
Interpretation & review guidance
A Supabase anon (public) key. This key is meant to ship in clients, so its presence is expected — it is only an exposure if your tables' Row-Level Security is off, which is exactly what our live check tests. Marked low unless verified.

infoApplication data is backup-enabled1 occurrence
Interpretation & review guidance
The app allows Android backups (android:allowBackup="true"). App data can then be extracted via adb backup on many devices — a concern if the app stores tokens or personal/health/payment data locally. Common and low-severity, but worth disabling for sensitive apps.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Draw over other apps
Requested permission inventory (43)
Data collection & flow (privacy signal, not part of the grade)
- Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 5 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
- Photos & files data requested with third-party analytics/ad SDKs present.
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.

Embed this grade
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/4f5788e8-811c-468b-9a99-7434844b07ec/findings.sarif (also coverage.json and proof.json).
