For developers and the curious
The evidence, sources, measurements and versions behind every label above.
Findings that met the published evidence standard.
The store privacy disclosure (3 entries) names no tracking or advertising use, but the package ships 17 advertising/tracking SDKs: Amazon Publisher Services, AppLovin MAX, BidMachine, Chartboost
Tracking or advertising SDKs are present in the package that the store's own privacy disclosure does not account for.
Bundles 16 distinct ad networks / mediation SDKs: Amazon Publisher Services, AppLovin MAX, BidMachine, Chartboost and 12 more
The package embeds several distinct advertising or mediation SDKs — a stack built for ad volume, not for a single house ad.

sha256:6afd7df5f402d5c3db4dce01d0c27d9089d4869b9bed3d4b86a5465249bdbbd5Facts that add context without being a charge.
Requests 12 sensitive permissions (ACCESS_BACKGROUND_LOCATION, ACCESS_COARSE_LOCATION, ACCESS_FINE_LOCATION, ACTIVITY_RECOGNITION, CAMERA, READ_CALL_LOG, READ_CONTACTS, READ_EXTERNAL_STORAGE, READ_MEDIA_IMAGES, READ_PHONE_STATE, READ_SMS, …
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.

The app's own text says: "Parsing data without ad"
This observation has not cleared the required evidence standard.
Advertising volume or placement that interrupts normal use: ads between every action, unskippable or forced full-screen ads.

This observation has not cleared the required evidence standard.
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.

This observation has not cleared the required evidence standard.
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.

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

rdfitAssessed 2026-10-26 from 400 user reviews, the app's package, the store listing and its privacy label.
What the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
No itemized purchase list is available for this listing.
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.
