Hi @Muhammad, extremely sorry for the inconvenience. Unfortunately, there is no backup option.
For your information, in toWP homepage it is clearly stated that your website will be available for 7 days. After that it will be removed. toWP is built for testing WordPress plugins and themes. If you built anything you can use plugin like WP ALL Import to transfer your site to your hosting.
