Is K MANGA safe?

It collects a lot of your data itself.

Our take. Its own App Store privacy label declares K MANGA links 10 categories of your data to your identity, and shares data to track you across other companies apps and websites, including purchases, location, contact info and user content. That collection, more than any outside tracker, is the story here.

What it collects about you

K MANGA links 10 categories of your data to you.

From the developer's own App Store privacy label. These are the kinds of data K MANGA ties to your identity, and it also declares it shares data to track you across other apps.

Who else is inside

It carries trackers from 6 companies.

Third-party SDKs found in the app, matched to the company that publishes each. Present in the code; we do not observe what they transmit.

How it compares

Where it sits among book.

Every one of these apps we have scanned, on the two measures above: third-party trackers it carries (across) and data it links to you on its own label (up). Toward the top right is more invasive.

Each dot is one book app. K MANGA sits high on the left: it collects a lot itself but uses few outside trackers.

Other signals

Two more flags.

Each is a fact read straight from the app. The same checks run on every app we scan. Only the ones that apply here are shown.

!

It declares cross-app tracking

Its own App Store label says it tracks you across other companies apps and websites using your advertising identifier.

!

It sends analytics to a company in India

InMobi is a India company. Its analytics SDK is built into the app.

The evidence

How we know this

Counterspy downloads the app from the App Store and statically analyzes its compiled binary. Embedded SDKs are matched against a signature database and resolved to the company that operates each. We also read the developer's App Store privacy label, which lists the data the app says it collects and links to you. We do not run the app or intercept its traffic, so we report capabilities present in the code and the developer's own disclosures, not proven transmission. We assess privacy and data collection, not malware, security flaws, or developer intent. Reports are automated and never edited for payment. Scan v3.0.1, 2026-04-04.

  1. Third-party trackers are advertising, analytics and attribution SDKs detected by static signature matching. Presence shows a capability is compiled in, not that it ran or transmitted data.
  2. "Data the app links to you" is the count of data categories the developer declares as Data Linked To You in its App Store privacy label. Labels are self-reported and not verified by Apple.
  3. Comparison across the 82 book in our corpus. Trackers: median 5. Data linked to you: median 3.
