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+

Every app is decompiled at source-code level, not just scanned from outside.

Critical
Flo, a period-tracking app used by more than 70 million people that holds data on menstrual cycles, symptoms and pregnancy, at least sent the disclosure to a real data-protection officer rather than customer service. The UK regulator's own complaint inbox bounced the follow-up, meaning anyone wanting to escalate has to use a separate web form instead.
