Refunds & delivery

How delivery works

Everything here is a digital download. The moment payment clears, the file unlocks on a page you can revisit, and the same link is emailed to you. Download links are signed and expire, so keep the file once you have it rather than relying on the link forever.

Checkout is handled by Whop, which acts as merchant of record — it takes the payment, issues the receipt, and handles any sales tax due in your country. You do not need an account on this site.

The seven-day refund

If a file is not what the page said it was, email hello@zllib.com within seven days of purchase and I will refund it in full. No form, no reason required.

I ask two things:

• Tell me what was wrong if you can — it is how the next version gets better.
• Delete the file once the refund clears. A refunded file is not licensed to you any more.

Refunds go back through Whop to the original payment method. Card refunds usually land in three to five working days.

What is not covered

• Change of mind after you have used the file commercially. If you stitched the chart and sold the finished piece, the file did its job.
• Buying the wrong thing twice. If you bought a single chart and then the bundle, email me — I will refund the single rather than leave you paying twice.
• Platform outcomes. No refund is offered on the basis that an account did not grow. Nothing here promises growth, and that is stated on every page.

If a download fails

Email me with the order email address and I will send the file directly, usually the same day. This has happened twice: once with a corporate firewall blocking the download host, once with a browser that could not open the PDF viewer. Both were fixed by emailing the file.

EU and UK buyers

Digital content is normally exempt from the 14-day right of withdrawal once download has begun. I offer seven days anyway, as a matter of policy rather than obligation — so the statutory exemption does not limit what you get here.
