I saw on our forum Neo is on holiday now.

But The Advertising Identifier (IDFA) is a temporary device identifier used by the Apple set of handheld devices. It provides device identification while giving end users the ability to limit the device/consumer information accessed by advertisers or apps (for example games). This number can be found on your device: go to Setting then click on General and next click on Info - I do not know what are names of these in 🇩🇪 language 🙃 but there will be a serial number that is assigned to each iOS-powered device.

This is a screenshot of an explanation how it works from that article
