Elnur Mehdiyev · Build 1.0.50
Static checks identify review items, not a guarantee of safety.
Overview
1 high or critical finding category to review
ELMA IoT – ESP32 Toolkit (com.elmaiot.app) scored grade F, 0 out of 100, in a static scan of version 1.0.50 on 2026-11-07. It has 1 high or critical finding category of 2, across 11 occurrences. 4 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.

highPrivate key material10 occurrences
Interpretation & review guidance
A complete PEM private-key block is embedded in the app. This is a real finding worth review — but it is often a bundled library test/sample key rather than a production secret, so we flag it high and leave confirmation to you (a bare header alone no longer triggers it).

- Evidence
- 10 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- Static detection; current reachability is not established.
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.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.

Data collection & flow (privacy signal, not part of the grade)
- Precise location, Approximate 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 3 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
- 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.

Embed the latest grade
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/a5726b7a-a1e4-49bb-b734-e1714e635d6f/findings.sarif (also coverage.json and proof.json).
