Found in the Android app’s package
Definition

The package embeds several distinct advertising or mediation SDKs — a stack built for ad volume, not for a single house ad.

Developer says data deletion can be requested

Measured

The developer's store data-safety disclosure states that data deletion can be requested; we have not seen a deletion control in the app's own text

Sources
The app's own on-screen text and the store listing
Agreement
A measured fact from one deterministic, checkable source.
Where measured
Found in the Android app’s package. From the Google Play listing
Definition

The developer's data-safety disclosure on the store states that users can request deletion of their data, or the app's own text offers a way to delete the account. This restates what the developer declares; it is not a test of whether deletion works. Apple publishes no equivalent disclosure, so on an Apple-only listing only the app's own text can support it.

Open evidence

Open observations that have not cleared the evidence bar.

Tracking and data collection concerns

One source only

The app requests QUERY_ALL_PACKAGES, which lets the app enumerate every other app installed on the device.

Where measured
Found in the Android app’s package

This observation has not cleared the required evidence standard.

Definition

The app ships session-recording or a wide tracking stack, holds permissions that read personal data, or is reported by users to sell, leak or over-collect it. The evidence line says which of those was observed.

Loot boxes with no stated odds

This observation has not cleared the required evidence standard.

Definition

The app sells randomised rewards — crates, chests, packs, pulls — and states no drop rates or odds anywhere in its own text, so what the money buys is unknowable before paying.

Trial terms not stated in the app's own text

Sources

Agreement

Where measured
Found in the Android app’s package

This observation has not cleared the required evidence standard.

Definition

The app's own screens offer a free trial without stating, beside it, what happens when the trial ends. Read this as context rather than as a charge: renewal terms are normally shown on the store's purchase sheet instead, which we cannot see, and we can only observe one kind of evidence for this — so it is shown, but never counted as a charge.

Where measured
Found in the Android app’s package

This observation has not cleared the required evidence standard.

Definition

The app's own screens offer a way past sign-up — guest access, skipping, or browsing before registering — rather than gating the product behind an account. The store's privacy disclosure is checked alongside it: that disclosure is self-reported, so it corroborates this credit rather than establishing it.

Definition

The app's own copy describes working without a connection — offline mode, downloading for offline use, or content saved for later. Shown because readers filter on it; it is a feature, not a fairness property, and never counts for or against an app.

A sampled review illustrates one person’s experience. It does not establish a finding on its own.

Measurements

8 measured · 0 not assessed

“Not assessed” means we could not measure it. It is never a zero and never a pass.

Themes reported by reviewers

Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings

Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

In the app package we scanned

Android package 3.5.29_ww, scanned 27 Oct 2026. These describe that package, not the current store version.

Sensitive permissions
3–5 requested
Counted against a fixed list of eighteen sensitive Android permissions: sixteen runtime permissions, among them location, camera, microphone, contacts and SMS, and two the user must switch on in system settings, drawing over other apps and usage access. Requesting one is not itself a finding.
Analytics or tracking SDKs in the scanned package
3 or more found
Advertising SDKs in the scanned package
10 or more found
Counted as distinct SDKs in the package we scanned. One mediation bundle can contribute several, so this is not a count of advertisers.

Method and limits

What this report can and cannot show

How the automated analysis works

This assessment is produced automatically. Six independent signals are read — user reviews, SDKs in the app package, the app's own on-screen text, the app manifest, the store listing and the store privacy disclosure — and each candidate finding is filed under the sources that support it.

No charge stands on one kind of evidence — with one published exception. A finding is either a measured fact that anyone can reproduce (an ad SDK is in the package; every subscription bills weekly; the privacy label omits a tracker we can see), or it is an interpretation — and an interpretation needs independent sources to agree before it reaches the catch list. The exception is a harm only users can see: a charge may publish from reviews alone, as “Reported by N users”, once enough reviewers raise it to clear that charge’s own published bar. That agreement rule is what replaced the human reviewer, not a model’s confidence.

There is no overall score, on purpose. A 0–99 number was published here until 2026-09-15. It was withdrawn because it discriminated too weakly to be the instrument — 44.7% of every pair of apps tied — and because a single number is a verdict where a count is an observation. What publishes instead is a row of measurements, each of which says what was counted and, where we could not look, says that instead.

Findings under One source only are real reports we do not stand behind as findings. They are shown because withholding them entirely would hide a genuine complaint, and labelled because publishing them as charges would be an accusation off a single source.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A hands-on test can confirm or contradict a finding and adds its own measurements; it does not change a measurement row. Hands-on inspections are not yet open.
