I no longer own any apple products but keep getting charged .99cents a month for cloud storage. How can I cancel if I have none of theses products?

If you have iCloud for Windows on a Windows computer you can cancel from that. See instructions in: Downgrade or cancel your iCloud+ plan - Apple Support

If not and if you don't want to install it, see the following from the same support article:

• If you don't have one of these devices, contact Apple Support to change your iCloud+ plan.
