Custom fields

Will the existing custom fields from my Book Collector desktop program transfer to my existing CLZ Book app? Will I have to clear my CLZ cloud info to make this happen?

“User Defined Fields” from the old Windows version will not sync to the new “Custom Fields” feature on mobile. They will only sync between the CLZ Books Web app and CLZ Books Mobile app.
We do offer a one-time import to get your User Defined Fields to the web-app, and from then on you can sync them with the mobile app. This does mean you have to switch your subscription over to the Web-app and stop using the old Windows version.

So to get your User Defined Fields to your mobile app, you need to perform 3 steps:

  1. Start a trial of the CLZ Books Web app
  2. Import your user defined fields to the web-app with our special tool
  3. Completely switch your old Book Collector Windows license and subscription over to the CLZ Books Web app

1: Start a trial of the CLZ Books Web app:


  • First, make sure your CLZ Cloud is up-to-date. In Book Collector, just Sync with CLZ Cloud.
  • Now go here and log in with your existing CLZ Account: https://app.clz.com/books/login?startTrial This will automatically start your 7-day free trial.

2: Import your user defined fields to the web-app with our special tool:



3: Completely switch your license over to the web-app:


This means letting go of the old Book Collector Windows software. You will completely move to our web-app and eventually uninstall the Book Collector Windows software from your computer.

You can do this through our generous Trade-in Offer: we will trade-in your remaining Book Collector subscription days and will transfer them to CLZ Books Web, plus we will add 4 extra months for free.
