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.
1.04M+
Smali classes read
The full shipped code we have actually read, not an estimate.
262+
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.
132+
SDK instances mapped
Reusable libraries correlated across the entire corpus.

Silent
Critical
McDonald's Austria first tried to wave off one of its two apps as someone else's problem in another country, even though that app's own code shows it runs on the same European infrastructure as the other one. Both apps leave payment and order data exposed to interception because their security configuration files are technically present but completely empty, and both apps send detailed ordering behavior to US advertising companies.
Two apps, twelve findings, all re-scored under CVSS v4.0. Both apps ship an empty network_security_config (no cleartext protection, no cert pinning, false security signal), both reaching CRITICAL on the computed score alone. Loyalty app: four hardcoded Firebase keys confirm EU-West production infra (prd-euw-gmal-mcdonalds); ACCESS_ADSERVICES_CUSTOM_AUDIENCE feeds dietary ordering history into behavioral ad auctions; a purpose-built triple US tracking stack (Kochava+Braze+mParticle). McDelivery: 2 hardcoded API keys, Facebook Conversions API sends order value to Meta, IMEI+phone number access, a 10-service Firebase stack. McDonald's Austria replied once (24.06) claiming McDelivery "appears to be related to McDonald's Philippines" - corrected same day citing McDelivery's own EU-West Firebase project compiled into the Austrian Play Store build. No further reply on either app since.
