They deleted my vault from my SSD and I couldn’t recover it! but I remembered that I bought obsidian sync for a month in 2023. Is there a possibility that they still have my files saved? Will my vault be available for download if I pay for Obsidian sync again?
I’m so sorry, but I doubt it.

I understood! thank you very much. I have the notes because luckily I compressed them to send to my cell phone, but unfortunately without photos and videos. anyway, thank you very much
