How to check iCloud (paid) renewal date?

I'm completely lost. I'm pretty sure that I checked everywhere (iCloud settings, Apple ID account info, 'Manage subscriptions' menu, etc.) but I can't find the date of renewal of my 50GB extra storage subscription. Of course, I could search my mail inbox, but I pretty much delete all the reciepts/ads from Apple without reading them, so that's not an option for me.

Any ideas?

Thanks,

Adam.
