This WooCommerce plugin prevents a user from being able to purchase a downloadable product that they already own. In place of the “Add to Basket” button on the product page, a message will display informing the user they already own the item, and links to download the linked files are provided there. Those links are the special links to the file that are provided on the “My Downloads” page, or part of the “My Account” page.
If the user has had a refund for the item the normal “Add to Basket” button will show again, allowing purchase.
On any page that displays the products other than the single product page, the button shows as “Read More”, as though the product is not available.
The plugin is very fast, works together with WPML and can show the output in any language!
Now it also works with WooCommerce Subscriptions!

<a href="https://www.lemonink.co/how-to-use/woocommerce" rel="nofollow ugc">LemonInk</a> is a cloud service used to secure digital books from piracy. It applies a digital watermark to each purchased ebook making it unique and traceable.
Using this plugin, you can easily integrate LemonInk into your WooCommerce store just by marking products as downloadable and assigning a master file (the original ebook) to them.
After each purchase LemonInk will create watermarked versions of your ebooks and attach them to user’s order allowing them to easily download their individual copies.
Note that you need to have an account at <a href="https://www.lemonink.co" rel="nofollow ugc">LemonInk</a>, but you can easily set it up just by <a href="https://www.lemonink.co/register" rel="nofollow ugc">registering</a>. In order to watermark files you’ll also need to purchase some credits, but if you just wish to give it a try, there’s a test mode available.
