Privacy Policy
Last updated: July 30, 2026
This policy explains what data CPMKit.com collects, why we collect it, and what happens with it. We run a free calculator tool site supported by advertising. We do not sell your personal information. If anything here is unclear, reach out at contact@cpmkit.com.
Who We Are
CPMKit.com is a free advertising metrics calculator website. We provide CPM, CPC, CTR, ROAS, and other ad-related calculators along with industry benchmark data. The site is owned and operated independently. Our contact email is contact@cpmkit.com.
What Data We Collect
Calculator Inputs
When you use our calculators, the numbers you type — ad spend, impressions, clicks, budgets, and so on — are processed entirely in your browser. Nothing you enter into any calculator is sent to our servers or stored anywhere. The calculations happen locally on your device using JavaScript.
Analytics Data
We use Plausible Analytics to understand how people use the site. It collects pages visited, time on page, referral source, country, device type, and browser. This data is aggregated and anonymous — no cookies are used for analytics, and we cannot identify individual visitors. Plausible is privacy-friendly by design and fully GDPR-compliant without requiring a cookie banner.
Cookies
We use cookies for two purposes: advertising (our ad partners use cookies to serve relevant ads based on your browsing behaviour) and essential site functionality (such as storing your dark mode preference). You can disable cookies in your browser settings, though some features like dark mode may revert to their defaults.
Advertising and Third-Party Partners
CPMKit.com displays advertisements to support the site. These ads are served by third-party advertising networks. Our current and potential advertising partners include:
- Google AdSense
- Mediavine / Journey
- Other programmatic advertising partners
These advertising partners may use cookies, web beacons, and similar technologies to collect information about your browsing activity on this site and other sites you visit. This information is used to show you ads that are more relevant to your interests — a practice called interest-based or personalized advertising.
Google, as a third-party vendor, uses cookies to serve ads on CPMKit.com. Google's use of the DART cookie enables it to serve ads based on your visits to this site and other sites on the internet. You can opt out of the DART cookie by visiting the Google Ad Settings page at adssettings.google.com.
For more information about how Google uses data when you use our site, visit: policies.google.com/technologies/partner-sites.
Your Choices and Rights
- You can disable cookies in your browser at any time through your browser settings.
- You can opt out of personalized advertising through the Digital Advertising Alliance at optout.aboutads.info or the Network Advertising Initiative at optout.networkadvertising.org.
- If you are in the EU, you have rights under GDPR including the right to access, correct, and delete your data. Contact us at contact@cpmkit.com.
- If you are in California, you have rights under the CCPA. We do not sell personal information.
Children's Privacy
CPMKit.com is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us at contact@cpmkit.com and we will delete it promptly.
Data Security
We use HTTPS encryption across the entire site. Calculator data never leaves your browser. We do not store user accounts, passwords, or payment information. The site is hosted on Vercel infrastructure with enterprise-grade security standards applied at the platform level.
Third-Party Links
Our content may include links to other websites — ad platforms, benchmark sources, and related tools. We are not responsible for the privacy practices of external sites. Once you leave CPMKit.com, this policy no longer applies. Check the privacy policies of any external site before sharing personal information there.
Changes to This Policy
If we update this policy, we will change the "Last updated" date at the top of this page. Significant changes will be noted on the site. Continued use of CPMKit.com after changes means you accept the updated policy.
Contact Us
If you have questions about this privacy policy or your data, email us at contact@cpmkit.com. We read every message and will get back to you.
