Independent evidence report

The evidence behind this assessment

What we measured

Each line is a measurement published as a measurement, never a verdict.

How these are measured

Each line is a measurement, published as a measurement. Where we have not looked, the line says so rather than reading as a zero.

Themes reported by reviewers
1 theme reported
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
Under 65% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

In the package we scanned

From the package we downloaded and read — version 1.8.3, scanned 2026-09-26.

Permissions Android classifies as dangerous
3–5 requested
Counted against the eighteen permissions listed in collect-package.ts. A dangerous permission is one Android asks the user to grant; requesting one is not itself a finding.
Analytics or tracking SDKs in the scanned package
1–2 found
Advertising SDKs in the scanned package
3–9 found
Counted as distinct SDKs in the package we scanned. One mediation bundle can contribute several, so this is not a count of advertisers.

What the analysis found

App-specific findings, grouped by what each one rests on. How they are graded lives on its own page.

Methodology

The catch list 1

Charges we publish at a strength we stand behind: measured from an artefact, agreed by independent sources, or reported by enough users to clear that charge's own published bar.

Multiple ad networks bundled
Measuredfrom SDKs in the app packageartefact 07215b561ef2…
The package embeds several distinct advertising or mediation SDKs — a stack built for ad volume, not for a single house ad.
What we saw: Bundles 7 distinct ad networks / mediation SDKs: Amazon Publisher Services, AppLovin MAX, Google Mobile Ads (AdMob / Ad Manager), Meta Audience Network and 3 more

Positive evidence 1

Things this app does right, published at the same strengths as the catch list.

Developer says data deletion can be requested
Measuredfrom the store listingview evidence
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.
What we saw: 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

One source only — shown, not confirmed 1

A single kind of evidence. We publish these because withholding them would be the bigger distortion, and we do not treat any of them as a finding we stand behind.

Reported by users: Aggressive ad load

Advertising volume or placement that interrupts normal use: ads between every action, unskippable or forced full-screen ads.
