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.

CS deflect
Critical
Strava hardcodes an access key directly inside its app and ships a security configuration file that does not actually protect anything, leaving all 120 million of its users with no defense against a fake server pretending to be Strava's real one. When RFI-IRFOS tried to reach Strava's privacy contact, the email bounced, and the person who did respond redirected the report to a bug-bounty program instead of engaging with it directly.
