Does Inkarnate permanently store map links?

Let's say I want to import my map into a different software, such as Homebrewery. To do so, I can simply go into my map overview, right click open on browser, copy link and paste it into the other software. This seems to work, and if I modify my map the image on the other website doesn't change (which is what I was hoping for).

My question is, is this a safe way to store the link to my map? The link has an inkarnate.com extension, so I'm worried that inkarnate periodically deletes access to outdated map links. Does anyone know if this is the case? I could load my map pictures into a more permanent website built for that, but it'd be much easier if I can just use the normal link
