Independent evidence report
The evidence behind this assessment
This is where the page changes from an app-store listing into an evidence report: findings, important reviews, pricing and a dated history.
Which version this describes
When we ran this analysis, and what the store lists now.
This analysis describes version 26.15.0.260901787 of the app (the version number recorded inside the package we inspected), analyzed 2026-10-05 . The app may have changed since.
The store currently lists version 26.15.0.260901787, updated 2026-09-29.
What we measured
Each line is a measurement published as a measurement, never a verdict.
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
65–79% 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 26.15.0.260901787, scanned 2026-09-29.
Permissions Android classifies as dangerous
6 or more 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.
Graded bands · predicate set 1.4 · how these are measured
What the analysis found
App-specific findings, grouped by what each one rests on. How they are graded lives on its own page.
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
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 4 distinct ad networks / mediation SDKs: Google Mobile Ads (AdMob / Ad Manager), Meta Audience Network, Unity Ads, Vungle / Liftoff Monetize
Context 1
Measured and published because a reader would want to know — deliberately not a charge. The measurement alone does not show a harm.
Asks for more sensitive permissions than similar apps
The package requests substantially more of the device's sensitive permissions than the typical app in its category. This is a measurement, not an accusation: a permission is granted because a feature needs it, and a wide request list is a reason to look rather than a finding on its own.
What we saw: Requests 12 sensitive permissions (ACCESS_BACKGROUND_LOCATION, ACCESS_COARSE_LOCATION, ACCESS_FINE_LOCATION, CAMERA, PACKAGE_USAGE_STATS, READ_CALL_LOG, READ_CONTACTS, READ_EXTERNAL_STORAGE, READ_PHONE_STATE, READ_SMS, RECEIVE_SMS, SYSTEM_…
Positive evidence 1
Things this app does right, published at the same strengths as the catch list.
Developer says data deletion can be requested
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 4
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.
In the app's own text: A plan is pre-picked as 'recommended'
The purchase screen arrives with one plan already framed as the recommended or most popular choice, so the default is the app's preference rather than the user's. We do not compare the plans' prices, and only the app's own text evidences this, so it is shown, but never counted as a charge.
What we saw: Purchase screen steers the choice: "Best deal"
In the app's own text: Tracking and data collection concerns
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.
What we saw: The app requests QUERY_ALL_PACKAGES, which lets the app enumerate every other app installed on the device.
In the app's own text: Countdown-timer purchase pressure
The app's own purchase copy attaches a deadline to buying — a countdown, 'offer ends in', 'limited time' — or ships a countdown view on a purchase-screen layout.
What we saw: Deadline pressure in the app's own copy: "Limited offer"
Reported by users: Aggressive ad load
Advertising volume or placement that interrupts normal use: ads between every action, unskippable or forced full-screen ads.
What we saw: Aggressive ad load: raised by 6 distinct reviewers (0.7% of 864 reviews scanned)
