School Hack
School Hack · Build 12.1.19
Static checks identify review items, not a guarantee of safety.
Overview
5 finding categories to review
School Hack (com.meets.schoolhack) scored grade B, 85 out of 100, in a static scan of version 12.1.19 on 2026-10-13. It has no high or critical findings, and 5 lower-severity finding categories across 6 occurrences. 7 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
mediumCleartext (HTTP) traffic permitted1 occurrence
Interpretation & review guidance
The manifest permits cleartext (HTTP) traffic. Data sent over plain HTTP can be read or tampered with on the network; modern apps should require HTTPS.
- 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.
mediumcom.squareup.okhttp3:okhttp 3.12.13 — CVE-2021-03411 occurrence
Interpretation & review guidance
The app bundles a third-party library whose declared version matches a public security advisory (CVE). This is flagged from the version the library itself ships and a curated advisory list — confirm exploitability in your context and update the dependency to the fixed version. It is not a proof of live exploitation.
- 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.
lowData Safety label omits Location1 occurrence
Interpretation & review guidance
The app's Google Play Data Safety label omits a data category it can actually access — a permission it requests, or an advertising/device identifier it references. Under-declaring collection is a Play policy issue and a COPPA/privacy concern. This is a static signal: a requested permission is capability, not proof of collection — confirm against runtime behavior.

lowFirebase Storage bucket reference2 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.

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.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Precise location Camera Microphone
Requested permission inventory (37)
Data collection & flow (privacy signal, not part of the grade)
- Precise location requested while 1 ad/attribution SDK(s) are present (Google AdMob) — location commonly feeds ad targeting.
- 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.
- Camera, Microphone 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.
Data Safety: declared vs observed (Play label vs our analysis)
We compare the developer's Google Play Data Safety declaration with what the binary can actually do (permissions it requests, identifier APIs and third-party SDKs it ships). A mismatch is a capability signal to confirm — a requested permission is not proof of collection.

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/ac8351ff-6e53-444c-92d3-e25a426d4b0f/findings.sarif (also coverage.json and proof.json).
