Overview

Analysis recorded

2 finding categories to review

CleanBoost - Junk Cleaner (com.novabrain.tool.cleanboost) scored grade A, 98 out of 100, in a static scan of version 1.0.4 on 2026-10-03. It has no high or critical findings, and 2 lower-severity finding categories across 2 occurrences. 20 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

lowExported content provider without permission (third-party library artifact, shared across 232 unrelated developers)1 occurrence

Interpretation & review guidance

An exported content provider declares no permission. Other apps on the device may reach it — verify it enforces access control internally; this flags the attack surface, not a confirmed leak.

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.
Open in all findingsRequest a correction
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.

  • Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 18 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • Phone, 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.
