Yes, there are no restrictions on where you might use Personal Edition. If you have data available in an Excel file, starting up QlikView will take you through a simple process to get your data loaded and your first QlikView built within 5 minutes. There are various tutorials to help through this. There are only two limitations while using QlikView with the Personal Edition license:
QlikView Personal Edition works with local files only; you cannot share your QlikView file with another unregistered user, or load a QlikView file from another user. You cannot import an entire document layout (sheets/objects/security settings, etc. without the data) into QlikView Personal Edition. it may be necessary to install QlikView on a different computer (i.e. computer upgrade, replacement, etc.). In order to open documents created using the previous installation of QlikView, you will need to "recover" the files. Recovering files simply means that you are assigning an updated user key (old machine -> new machine) to these documents. When you recover a file, you are telling QlikView that you are moving this file to your new installation, and you will no longer be using it on your previous installation.
IMPORTANT: QlikView Personal Edition is limited to four recoveries per installation. When you recover a QlikView file created with a previous installation, it will apply your new user key to ALL documents created using the previous installation, not just that particular file.
DO NOT attempt to open QlikView files that you did not create (from the forums, created by a colleague, etc.) Doing so will use one of your remaining recovery attempts, and once you have exhausted all 4 of the attempts, you will no longer be able to access documents that you have created and, from that point on, you will only be able to create new documents using your current QlikView installation. in the case of QlikView is a bit difficult if you use the personal edition (then as said above you will be not able to share with other colleagues your apps.)
But you can use Qlik Sense (your own created apps you can share with other collegues), but in the case of Qlik Sense Server you should buy a Qlik Sense Server to publish your apps to EndCustomer.
i hope this information is useful for you and your business environment
