Custom Countdown Timer
FJLogics · Build 2.8.6
Static checks identify review items, not a guarantee of safety.
Overview
1 high or critical finding category to review
Custom Countdown Timer (com.custom.countdown) scored grade B, 81 out of 100, in a static scan of version 2.8.6 on 2026-10-07. It has 1 high or critical finding among 2 finding categories across 4 occurrences. 14 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
highPrivate key material1 occurrence
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
- 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.
lowFirebase Storage bucket reference3 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
- 3 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.

- Static detection; current reachability is not established.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Storage
Requested permission inventory (14)
Data collection & flow (privacy signal, not part of the grade)
- Persistent-identifier APIs referenced in code (Android ID, Device ID / IMEI, SIM serial +1 more) with 13 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.

Each row is an observed scan. Gaps between scans do not establish how long a finding existed.

Exports describe the recorded assessment. Signed evidence proves origin and integrity, not completeness or safety.

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/930cb1bf-f98e-4b33-a836-a452c7201deb/findings.sarif (also coverage.json and proof.json).
