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
WELT's news app feeds the categories of the articles you read, including politics, health and migration, into Google's advertising system to build an interest profile of you, categories that can reveal sensitive opinions you never meant to share. Your reading behaviour is also transmitted to a US marketing platform with no documented legal basis, and two separate marketing tools are already running before you have consented to anything.
de.cellular.n24hybrid. WeltN24 GmbH / Axel Springer SE, Berlin (XETRA: SPR, ~EUR 3.8B revenue), the 2nd Axel Springer app in this wave. C1: Firebase API Key AIzaSyDoIXY3… + DB welt-news-android.firebaseio.com + Braze CRM API Key 6ff42e90-7649-48be-b7f3-fa8537dc9c3c hardcoded (765 Braze smali classes, full CRM infrastructure exposed). H1: ACCESS_ADSERVICES_TOPICS - Google's Topics API generates advertising interest profiles from news article categories (politics, health, migration); on a news platform this raises possible Art. 9(1) GDPR special-category exposure (political opinions, health interests). H2: Tealium TMS + Google Mobile Ads, dual pre-consent (both initOrder=100), marketing tag stack initializes before consent. H3: Outbrain Native Ads (9 classes) + Braze US transfer, no Art. 44-49 GDPR mechanism. R1 sent 2026-06-30. BlnBDI + EDPS in CC. Embargo 2026-09-28. Deadline 2026-07-14.

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.
