Yes, once you purchase an eBook, it is yours to keep. Your purchased books are saved in your knigdom.com account, so you can access them at any time by signing in with your username and password. Most formats allow you to download your books as many times as you need.

If you purchased without creating an account, you can register later using the same email address you used at checkout. Your previous purchases will then be automatically linked to your account, giving you easy access to your books.
