1. Amazon Associates Participation Statement
SkyMotion.tools (authored by Traian Anghel) is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com, Amazon.co.uk, Amazon.de, and affiliated international Amazon marketplaces.
As an Amazon Associate, SkyMotion.tools earns from qualifying purchases. This means that if you click on a curated book recommendation, telescope reference, or physics measurement instrument on our site and subsequently complete a purchase, we may receive a modest commission at no additional cost to you.
2. Transparent Clean Link Structure
We believe in complete transparency regarding link formatting. All outbound Amazon affiliate links on this platform use clean, direct canonical product URLs tagged with our official associate tag skymotion20-20:
We do not use misleading cloaked redirectors, hidden affiliate scripts, or aggressive tracking pixels. Every commercial recommendation is explicitly identified with an "Amazon Partner Link" indicator or badge.
3. Editorial Independence and Curatorial Standards
As a practicing physics teacher with over 15 years of instructional experience, my product recommendations are strictly based on academic rigor and educational merit:
- Textbook & Scientific References: Books recommended across the site (such as Jean Meeus’ Astronomical Algorithms, Halliday & Resnick’s Fundamentals of Physics, or Petersen’s Field Guide to Stars and Planets) are genuine texts utilized in academic physics coursework and astronomy field observation.
- Zero Paid Placements: We do not accept sponsored placements, paid reviews, or promotional payments from manufacturers. A product or book is recommended only if it genuinely enriches the student or creator’s understanding of celestial motion, kinematics, or geometry.
- Cost Neutrality: Clicking an affiliate link will never increase the price you pay on Amazon. In many cases, it directs you to standard paperback, hardcover, or digital Kindle editions with the best available market pricing.
4. How Affiliate Revenue Supports This Site
Affiliate commissions generated through skymotion20-20 help cover domain registration fees, high-performance edge server hosting, and ongoing open-access maintenance of our free calculators. This allows us to keep SkyMotion.tools completely free of invasive full-page overlays, popups, and paywalls.
