I have a 100% mobile workflow, so I have removed Lightroom from my desktop. Now I'd like to buy some presets to use on my Lightroom iPad app. I understand that I have to import these to the desktop app first, before they will appear on mobile. However, what I'm wondering is if I can then delete the desktop app again - will the presets remain on the mobile app? Or would I have to keep them 'alive' in the desktop app?
