If you have installed Lightroom 3.3 then you don't have an option. That is the whole design of the program, to import your images to the cloud so that they are available for you to access on your computer, your mobile phone, your iPad or other such device, etc., and be able to edit them on those devices and be able to share them from those devices. If that isn't your intent, and you want to keep your images on your computer then you should possibly consider Lightroom Classic. That program utilizes a local catalog and imports images to folders on your local hard drive or other hard drives that are connected to your computer.
Yes I want offline version of SW for photos editing. No cloud or anything like that, I dont want upload any my photos anywhere. I installed as you suggested LIghtroom Classic, but still I'm not able disable uploading files. Can you show me where I can do that?
If you are now only using Lightroom Classic then the only time images will be synchronized to the cloud is when you create collections and specifically choose to synchronize the collection. But even then those images will be synchronized as smart previews, and will not impact your cloud allotment. But if you really don't want any images in the cloud didn't do as Johan has indicated.
