Lifespan of ionic playground links

Hey guys, despite my first scepsis I’m really looking forward to use ionic now^^

I finished my click prototype with the ionic creator and now wanted to use the ionic playground’s preview links to have an already designed prototype I can show to users and use as my GUI code base.

So I made just a Welcome-Page in the Ionic Creator who then links to the whole Playground UIs.

I am just wondering how long you save those code-snippet URLs?
