Help & Contact

How do I get my notes after I buy?

As soon as your payment goes through, download buttons appear on your order confirmation page. I also email you the download links.

I haven't received my download email

Check your spam or junk folder first. If it isn't there after a few minutes, email hello@aeroemilia.com with the email address you used at checkout and I'll resend your links.

How many times can I download my files?

As many times as you need. I'd still recommend saving a copy to your device or cloud storage.

Can I see what's inside a pack before I buy?

Yes. Every product page shows the number of pages and a page-by-page list of the topics covered, plus preview images.

How does "buy 4 packs, get the 5th free" work?

Add any 5 packs to your basket and the cheapest one is free. It's applied automatically at checkout, so you don't need a code. It can't be combined with other discount codes; checkout gives you whichever saves you more.

Can I buy a whole series at once?

Yes. On any pack that's part of a series (like Boundary Layers I–IV), use the link under the Add to cart button to add every part in one go.

Can I get a refund?

Because the notes are instant downloads, you lose the usual 14-day right to cancel once you download them. If a file won't open, pages are missing, or the notes aren't as described, email me and I'll fix it or refund you. Bought the same pack twice? I'll refund the duplicate. See the Refund policy.

Can I print the notes or share them?

You can download them, keep them on your devices and print them for your own study. Please don't share, sell or upload them anywhere else. See the Terms of service.

Are these official university notes?

No. They're my own handwritten notes from my aeronautical engineering degree. They aren't official teaching materials from any university, and no university has provided or endorsed them.

Can I pay in my own currency?

Prices are shown in your local currency in many countries. You can change currency using the selector at the top of the page.

Is anything posted to me?

No. Everything is a digital download, so there's no shipping and no delivery charge.
