What you’re buying
NanoBubbleGuide sells digital e-books (PDF) on ultra-fine bubble (UFB) / nanobubble technology. All products are digital downloads — no physical items are shipped.
Delivery
E-books are delivered as an instant digital download once payment is confirmed. A download link is also sent to the email address used at checkout.
Payment
Payments are processed securely by Stripe. We do not store your card details.
Refunds
Because e-books are delivered instantly as digital files, we don’t offer refunds once a file has been downloaded. If something’s wrong on our end — the file won’t open, or the wrong title was delivered — contact us at info@nanobubbleguide.com and we’ll sort it out.
Usage
E-books are for your own personal or internal business use. Please don’t redistribute, resell, or share the files.
Content
NanoBubbleGuide is an independent publisher. We are not affiliated with, and do not receive payment from, any nanobubble equipment manufacturer. Content reflects our own research and analysis, and should not be taken as engineering or safety advice for a specific installation.
Governing law
These terms are governed by the laws of England and Wales.
