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.

Fluege.de records your screen and captures your flight searches, travel dates and destinations before you have consented, using a consent tool the app itself bypasses. It can also dial phone numbers on its own without asking you first, and uses your location to target flight advertising to you.
Fluege.de / Invia Group (de.unister.fluege). Usercentrics CMP (335 classes) present but bypassed: FirebaseInitProvider initOrder=100 + Adjust SystemLifecycleContentProvider fire before consent. Microsoft Clarity (750 classes, largest SDK in app) session recording - captures flight search queries, travel dates, destination on screens before consent. All four Privacy Sandbox APIs simultaneously: AD_ID + ATTRIBUTION + TOPICS + CUSTOM_AUDIENCE - first app in series with complete set. CALL_PHONE: auto-dials without user confirmation. RECEIVE_BOOT_COMPLETED. Braze (444 classes) with location module - geofenced targeting on flight booking data. Firebase key AIzaSyAROfZ5e5mbLbKViJi6xq6qqgWtG_ltKn0 hardcoded, project fluege-2. BfDI = lead authority. Six messages sent across 77 days to datenschutz@fluege.de; privacy@/security@fluege.de bounced. Not one reply of any kind was ever received. Case closed and published 2026-09-25, on the stated embargo date. BCC: BfDI + DSB + CERT.at.
