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)."
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.
@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 - 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
Just wondering how I can make sure that the visitor ID remains consistent across all these steps. Appreciate your thoughts and guidance on this.
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?
In an earlier post in this thread (that post appears to have been deleted?), it was stated that the Visitor ID was partially generated using information specific to the device.
I simply wanted to clarify that device information is not a part of the process used to generate a Visitor ID.
Yes, when a user un-installs the app and re-installs it later, a new unique visitor ID will be created. But If your app opens mobile web content, you need to take extra steps to ensure that visitors are not separately identified as they move between the native and mobile web. You can view this documentation to ensure that - https://marketing.adobe.com/resources/help/en_US/mobile/android/hybrid_app.html
Yes, the uinque ID will remain unchanged when a user clears app cache or data. The ID is a combination of Device ID and identifier from SDK. Let me know if thats helpful. Thanks!
