Overview

Limited assessment

4 finding categories to review

StretchOut (com.youloft.google.stretch) was scanned at version 1.1.2 on 2026-09-02 but is not graded, because the analysis did not complete enough of its checks for a score to mean anything. The checks that did run recorded 4 finding categories across 4 occurrences; because the analysis did not complete, the absence of anything more severe is not a result. 6 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.
Open in all findingsRequest a correction
lowApplication 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.

Evidence
1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.

lowFirebase Storage bucket reference1 occurrence

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.

  • Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI +3 more) with 5 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • Camera, 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.

Data Safety comparison is not conclusive because analysis coverage is incomplete or unknown.
