Frequently Asked Questions

What is Dargslan?

Dargslan is an IT eBook store run by Dargslan s.r.o. (Slovakia). We offer 276+ eBooks on Linux, DevOps, cloud, networking, databases, security, Windows and more, all as instant DRM-free downloads in PDF and EPUB.

How do I download my eBooks after purchase?

After paying with card (Stripe) or PayPal, you receive an email with a secure download link right away. The link is valid for 7 days and allows 5 downloads per book. If you have an account, your purchases are also in My Library. If your link expires, contact us and we will reactivate it.

Can I get a refund on digital purchases?

We do not offer a general voluntary money-back guarantee or change-of-mind refunds for downloaded eBooks. The digital-content withdrawal exception applies only when all legal requirements are met, including prior express consent, acknowledgment and the required confirmation, and supply begins with downloading. Rights concerning defective or non-conforming content and incorrect charges remain unaffected. See our Refund Policy or contact support to make a request.

Are the eBooks regularly updated?

Yes. We add new titles regularly and update existing ones. When a book you bought is significantly updated, the new files are made available in your account library at no extra charge.
