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.

RESOLVED
CRITICAL
Decathlon's app is built to start recording your screen before you have even opened it or agreed to anything, and this recording function is deliberately configured as the very first thing the app runs. It also tracks your movement inside stores using Bluetooth beacons linked to your customer account, detects when you take a screenshot of the app, reads your phone's fixed hardware identifier, and sends your marketing data to a US company.
com.decathlon.app. Decathlon SE, Villeneuve-d'Ascq, France (~EUR 17B revenue, 1,700+ stores, 60 countries). C1: 2x Firebase/Maps Keys hardcoded. C2: Luciq (Instabug) APMContentProvider android:initOrder="2147483647" (Integer.MAX_VALUE), configured architecturally as priority #1, a deliberate decision, not a tooling default; ScreenRecordingService + ScreenshotCaptureService both with foregroundServiceType="mediaProjection", the screen-recording SDK starts before consent, before app logic, before everything. H1: AltBeacon BeaconService (foregroundServiceType=location), BLE beacon in-store movement tracking in stores, linked to the loyalty profile. H2: Salesforce Marketing Cloud (1,859 smali classes) + MCInitContentProvider, US transfer with no Art. 44-49 GDPR mechanism. + DETECT_SCREEN_CAPTURE + READ_PHONE_STATE (IMEI) + Medallia 821 classes + Adjust + Firebase pre-consent reserved. R1 sent 2026-06-30. CNIL + DSB + EDPS in CC. Embargo 2026-09-28. Deadline 2026-07-14. Eight messages over 103 days drew only automated acknowledgments in Portuguese and German, never a human reply. Case closed and published 2026-10-17, 19 days after the embargo.

this is a useless cookie banner. it's just here to look like one * we don't use cookies, so there's nothing to consent to. don't let anyone tell you otherwise.two buttons, one closes this and throws some confetti. the other literally does nothing.
