Mobile Werbe-IDs und In-App-Tracking
Apps use resettable advertising identifiers — IDFA on iOS and GAID on Android — plus SDK event streams to target ads and measure installs across apps on the same phone.

IDFA, GAID und Opt-out
IDFA (Identifier for Advertisers) on iOS and GAID (Google Advertising ID) on Android are designed for ad measurement. iOS App Tracking Transparency (ATT) prompts you to allow or deny cross-app tracking per app.
You can reset these IDs in system privacy settings and limit personalized ads. Denying ATT does not stop all analytics — first-party SDK events inside an app may continue.
SDKs, MMPs und SKAdNetwork
Apps embed SDKs from Meta, Google, Adjust, AppsFlyer, and others. Events like app_open, purchase, and level_complete feed ad optimization.
SKAdNetwork on iOS provides privacy-preserving install attribution to ad networks without returning the raw IDFA. Deep links can still pass campaign parameters into the app when you tap an ad.
In-App-Tracking-Stack
- IDFA / GAID — cross-app ad identifiers
- App SDK events — in-app behavior streams
- MMP postbacks — install attributed to ad click
- App-to-web bridges — same login links app and browser
Browser-Analyse vs. mobile Apps
Our site runs in your mobile browser, not inside native apps. We cannot read IDFA/GAID. We do show browser signals on mobile Safari/Chrome that trackers combine with app data when profiles merge.

- See cross-device tracking for how app and web profiles merge.

If I deny tracking on iOS, am I private in apps?
Cross-app IDFA sharing stops, but the app may still collect first-party analytics and show ads based on context or broad cohorts.
Are mobile ad IDs the same as cookies?
Similar role for apps. They identify your device for ad systems. Resetting them starts a new ad profile on that device.
Do free apps track more?
Ad-funded apps often include more ad and analytics SDKs. Check privacy nutrition labels (iOS) or Data safety (Android) before installing.
