Privacy Policy

Calculator values are processed in your browser to produce results and are not intentionally submitted to our servers. We may receive limited technical information such as browser type, device information, approximate location derived from IP address, referring pages, and usage events through hosting, security, and analytics services.

This site is funded by advertising. We work with third-party ad networks, currently including Adsterra (Adsterra Network, adsterra.com) and Google AdSense. These networks and their demand partners deliver display, native, and other ad formats on pages of this site.

Ad networks may use cookies, web beacons, pixel tags, and device or browser identifiers to select ads, limit how often the same ad is shown, measure performance, and detect invalid or automated traffic. Some of this activity may involve information about your visits to this and other websites. We do not receive, control, or sell the personal data these networks collect through their own tags and cookies.

Each network processes data under its own privacy policy. For Adsterra, see the Adsterra privacy policy. For Google, see the Google partner sites policy.

Cookies and similar storage may be set by us (for basic site function) or by advertising and analytics providers (for ad delivery, frequency capping, fraud prevention, and measurement). Where the law requires it, we ask for consent before non-essential cookies or identifiers are used. You can withdraw consent at any time through the cookie or consent controls shown on the site, if present.

You can limit interest-based advertising using the opt-out tools offered by the industry: YourAdChoices (DAA), Your Online Choices (EDAA), and NAI opt-out. Google ad personalization can be controlled in Google Ads Settings. Opting out does not stop ads from appearing; it makes them less relevant.

You can also block or delete cookies and site data in your browser settings. Blocking all cookies may affect advertising preferences or some website functions.

Technical and usage information may be used to operate and secure the site, diagnose errors, understand aggregate traffic, improve content, measure advertising performance, and comply with legal obligations. We do not sell calculator inputs as personal information.

Our hosting, analytics, and advertising providers process information under their own privacy terms. Ads on this site may link to external advertiser websites; those sites operate independently and their privacy practices are outside our control. Review an advertiser's own policy before sharing information with it.

Information is retained only as long as reasonably necessary for the purposes described above or as required by law. We use reasonable safeguards, but no online service can guarantee absolute security.

The service is not directed to children under 13, and we do not knowingly collect their personal information. If you access the site from another country, information may be processed where our service providers and ad networks operate, subject to appropriate legal safeguards when required.

Depending on where you live (for example under the GDPR or CCPA/CPRA), you may have rights to access, correct, delete, restrict, or object to certain processing, and to opt out of the sale or sharing of personal information. We do not sell personal information ourselves; ad-network data is controlled by those networks and requests should be directed to them using the links above.

To submit a privacy request, or if you have questions about this policy, email service@cpmcalculator.world.

We may update this policy when our advertising partners, tools, or legal obligations change. The revision date at the top of this page always reflects the current version.
