Editorial & advertising policy
Evidence first.
Incentives visible.
What makes a lesson publishable
One learning objective, a relevant video, a written explanation that adds value, a visual example, explicit boundaries and a knowledge question whose options are individually checked for consistency. We keep observable facts separate from assumptions and do not invent performance statistics or expert credentials.
Editorial review
Software and AI assistance may be used in drafting, diagrams and production. This build’s exercises were individually checked for arithmetic, a single intended answer and explanations of the alternatives. That is not a claim of independent human or licensed-professional certification. The operator remains responsible for final publication review.
Correction process
Send the page URL, the disputed statement and supporting evidence to the contact in the legal notice. A substantive correction should update the explanation and exercise together, not merely change the answer key.
Advertising
No advertisements are active in the review build. Any future advertising will be visibly marked and separated from lesson instructions, calculator results and quiz options. Approval and revenue from AdSense are not guaranteed. No affiliate recommendations or commission relationships are presently claimed.
Commercial-intent learning
Decision guides can help readers compare costs, order tools and risk features. They will explain criteria and trade-offs, not fabricate broker rankings, prices, reviews or endorsements.
