I probably not not fine with it. I have built my gallery so that I can go get my notes anytime I want repost them.  I take time selecting pics and texts Even my own photographes, my paintings, my writing and feelings I share here in a moment that I do not which to loose. How can I keep my data? I am here less than a year, I don't mind paying but I am not sure I have enough sats.... 

 This is just suggestions for now. Check out cellar.nostr.wine though if you're concerned about losing your notes 😊 

 This is a very good recommendation: relays where you can pay for long-term storage

If you’re technically literate/advanced, you could also run a private relay and ensure all of your posts are sent there. 

 You should probably be making a point to download your notes and other events to your phone or computer. They're your valuable product, so you should store them yourself. You own your own data here.
