If you plan to pause your subscription, switch stores, or temporarily deactivate your Shopify account, make sure to save your theme and any changes you've made so you can easily use them again later.
How to Save your Debutify Theme
STEP 1
In Shopify admin, under Online Store click on Themes.
STEP 2
Click on action /ellipsis and click on Download Theme File.
STEP 3
Click Send Email to get the files.
STEP 4
Check your email inbox and click theme export to download the theme file and save them locally on your computer for safekeeping.
When you sign up again, you can upload the theme once more.
Note: This action saves the theme and customizations only; media uploaded to Shopify will not be preserved.
