Current advertising status
CalculTools is prepared for advertising, but ad placements should remain disabled or invisible until the site is ready for review and approval. Pages should not show “future ad” labels, empty ad boxes, or placeholder ad text to visitors.
Ad placement principles
- Ads should not block calculator inputs, results, or action buttons.
- Ads should not imitate calculator buttons or result panels.
- Ads should be separated from editorial explanations and formulas.
- Ad containers should avoid layout shifts on mobile and desktop.
Editorial independence
Calculator formulas, examples, disclaimers, related calculator links, and educational explanations are not changed because of an advertiser.
Advertising networks
If CalculTools uses Google AdSense or another advertising service, those services may use cookies or similar technologies to deliver, measure, and protect ads. Visitors can control cookies through browser and platform settings.
Sponsored content
If sponsored content is ever added, it should be clearly labeled. Calculator pages are built as free educational and utility content.
Advertising contact
Advertising or publisher questions can be sent through the contact page.
