When your animation is finished, and posted hit GIF under it. This will download it to your device. Then go to the website, ufile.io and drag the file into the box. This will give you a file that you can copy and paste :>

thats for sharing, when you just want to save to work on it later, in the editors you will see a little cog and when you see that there will be two buttons with arrows and paper, one will download the file, the other will reopen it :D
