Permanent Disclosure Ledger

The discipline, demonstrated

On behalf of our research partners, we investigate publicly distributed Android and iOS apps: we decompile them, follow their code and data flows, and trace every connection to the servers it reaches. Hundreds of agents work through each app and join the technical evidence into one picture, which our specialists then review and verify.

387+
Android/iOS apps audited
Every app is decompiled at source-code level, not just scanned from outside.

Smali classes read
The full shipped code we have actually read, not an estimate.

Critical findings recorded
Confirmed findings copied to regulators, not theoretical risks.
970+
Weak points found
Third-party tracking we have provably found inside the binary.
567+
Endpoints investigated
Real servers and countries where data actually flows.

Subway Surfers, one of the most-downloaded games in the world, ships an advertising SDK deliberately engineered to start before every other line of code in the app runs, before any consent screen, alongside six pre-consent ad trackers total, one of them Chinese-linked. The company's support inbox answered six times with the identical automated message, each time as if it were a brand new request, and never once addressed the actual findings.
com.kiloo.subwaysurf. All seven findings re-scored under CVSS v4.0. Six pre-consent ad/analytics ContentProviders, with Moloco's initOrder literally set to Integer.MAX_VALUE to guarantee first-fire priority, held at HIGH via blast-radius escalation (3.5B+ downloads, confirmed underage audience). All four Privacy Sandbox permissions incl. cross-app behavioral cohort targeting also HIGH via the same escalation. Mintegral (PRC/NSL), hardcoded Firebase key, and 10+ ad-network mediation stack correct to MEDIUM. SuperAwesome child-safe adapter sitting alongside the full adult targeting stack classified OBSERVATIONAL, a real structural contradiction without an independently scoreable technical path. 13 messages sent, 6 identical automated ticket acknowledgments each under a new conversation ID, zero substantive reply ever.

This ledger is updated in real time as companies respond. Silence is public. Severity is scored primarily by CVSS v4.0, we reserve the right to deviate based on blast radius.
