Advertising principles
AnswerCanvas is free to use, and advertising helps fund the calculator library. Advertising should be distinguishable from calculator results, formulas, editorial explanations, and professional notices. Editorial and calculation content is not for sale - an advertiser's participation never changes a calculator's formula or output.
Third-party advertising networks
AnswerCanvas may display advertisements served by third-party advertising companies, including Google AdSense. These companies may use cookies, web beacons, or similar technologies to serve ads based on your prior visits to this and other websites, and to measure ad performance and limit fraud. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Google Ads Settings, or opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info.
Personalized and non-personalized ads
Where consent is required by applicable law (for example, for visitors in the EEA and UK), personalized advertising is served only after you provide consent through our cookie preference control; visitors who do not consent are shown non-personalized ads where technically supported by our ad partners, or no ads at all in categories where non-personalized serving is unavailable. You can change your advertising cookie preference at any time using the cookie preferences control in the site footer.
Ad quality standards
- Ads should not obscure inputs, results, warnings, formulas, or accessibility controls.
- Ads should not imply endorsement unless a partnership is explicitly disclosed.
- Commercial placement must not change formula outputs or calculation methodology.
- We restrict ad categories that conflict with user safety, legal requirements, or platform trust, and we work with our ad network to address ads that violate these standards when reported.
- Advertising is not shown to, and is not knowingly targeted at, children under 13.
Measurement and reporting
Advertising partners may use cookies or identifiers for measurement, fraud prevention, frequency management, and reporting, and to help us understand aggregate ad performance across the site, where permitted by law and consistent with your consent choices.
