Independent evidence report

Evidence and review signals

This is where the page changes from an app-store listing into an evidence report: findings, important reviews, pricing and a dated history.

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
No 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 8.5.1, scanned 2026-09-13.

Permissions Android classifies as dangerous
1–2 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
None found
Advertising SDKs in the scanned package
None found
Counted as distinct SDKs in the package we scanned. One mediation bundle can contribute several, so this is not a count of advertisers.

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.

From the store listing: Usable without an account
One source onlyShown, not confirmed — the only source is the store privacy disclosure.view evidence
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.
What we saw: The store privacy disclosure (5 entries) links no contact details or identifiers to the user — consistent with an app that does not require an account. Self-reported by the developer.
