We decompile publicly distributed Android and iOS apps and trace their data flows to real endpoints in real countries. We document what we observe, distinguish verified findings from interpretation, and preserve the evidence behind every conclusion. No company can buy a better result — every organisation is held to the same standard, whether it pays us or not. This permanent disclosure ledger puts that principle into practice.
Every app is decompiled at source-code level, not just scanned from outside.

Müller's loyalty and payment app sends every network request unencrypted by default, on an app that also handles in-store payments. What you buy at a drugstore, medication or health products, can reveal sensitive information about your health even without being formally classified as medical data, and the app bundles two advertising and attribution SDKs alongside that purchase-profiling platform.

The purchase-category link to Adjust and Facebook was documented from the start as an inference from co-presence in the binary, not an observed transmitted payload, this static-only research programme does not run live traffic capture. Case closed 2026-10-17: eight messages, five substantive replies from Müller, cleartext HTTP and SYSTEM_ALERT_WINDOW verified fixed in v2.21.0, the AppsFlyer part of H-2 withdrawn by us, four Müller statements (Adjust consent gate, Facebook login only, key restrictions including Realtime Database, date of the threshold analysis) remain unverified.
