Deleting subscription services + saving photos

Hi everyone. I am posting in this forum as Lightroom is what I’ve used, and I cannot find a support email address to ask Adobe directly.

I subscribe to a 1TB/month cloud storage, as well as to the Creative Cloud monthly applications package. I am cancelling both services as I haven’t used them much in years. However, there are warnings upon cancelling that photos may be lost if I cancel. 

I’d like to not lose any of my photos, as I may want to pick my editing back up at a later time. Does anyone know the following:

If I cancel my services, if I re-subscribe later, will all my photos be there again in my photo library, or would I be starting from scratch with an empty library and need to re-import everything? If the photos would still be there - will any edits I’ve made still show up, or no? Also… my mind boggles with the locations of all of my photos - when I first started they all lived on hard drives nicely organized, but once services started switching to cloud I became very confused where things lived - does anyone know why I ought to be worried about losing photos, as the warning stated, or how to ensure that doesn’t happen?

Thank you very much, from someone for whom cloud storage and cloud based applications has been very confusing!
