unique visitor ID in mobile app

Hello,

recently I saw the following information about setting the unique ID for unique visitors in mobile apps.

"The SDK generates a unique visitor ID when an app is installed. This app visitor ID is stored within persistent memory on the mobile device and is sent with every hit. The app visitor ID is removed only when the user uninstalls the app (app visitor IDs persist through upgrades)."

source: https://marketing.adobe.com/resources/help/en_US/mobile/ios/hybrid_app.html

I try to figure out, whether when user clear app cache or data, visitor ID remains unchanged? I am curious because in our mobile application we register a suspicious number of new unique visitors...

Thank you in advance for your help.

Best,

Adrian

@Adrian, @Tanmay - 

It is accurate that a delete and reinstall of the app will cause a new visitor to be generated.  

I need to clarify that while clearing app cache will not cause a new Visitor ID to be created, clearing app data will result in a new Visitor ID being created.  Also worth noting that the SDK uses no information about the device when generating the Visitor ID.

Sorry for the confusion.  Hope this helps.

Hi all! I have a doubt similar to the initial one but the answers do not clarify my doubt. Checking the metrics of unique visitor and first lauches since I launched my app today I have more unique visitor than first launches, what is it?

Hi all  - Is there anyway to make sure the visitor ID remains consistent when a user comes to the app from mobile web ? This is the journey. I

  1. I have a micro site (desktop and mobile web)
  2. Users come to this site, click on download via app store or google play
  3. They go to the respective apps store and download the app
  4. Launch the app and start using it

Just wondering how I can make sure that the visitor ID remains consistent across all these steps. Appreciate your thoughts and guidance on this.

Regards,

Rahul
