CPM Calculator Pro processes all campaign calculations directly within your device's browser using client-side JavaScript. No budgets, impressions, CPM targets, or revenue numbers are ever transmitted to or stored on our servers.
1. Client-Side Calculations & Zero Data Transmission
Every mathematical calculation performed on CPM Calculator Pro — including total campaign cost, impression targets, CPM rates, conversion benchmarks, and budget allocations — is processed entirely within your web browser using client-side JavaScript. None of your entered numbers, campaign values, or financial figures are sent to our servers, logged in databases, or shared with third parties. Your commercial data remains strictly on your device.
2. Local Storage & Device Preferences
To enhance user experience across sessions, our site may utilize browser localStorage and sessionStorage to preserve your preferred currency display symbol (e.g., USD, EUR, GBP, JPY) and temporarily retain your most recent inputs when switching between related calculator views or language translations. This data is stored locally on your device only and is never transmitted to us. You can clear this data at any time via your browser settings.
3. Contact Inquiries & Communications
If you contact our team via email at hello@cpmcalculatorpro.org or submit an inquiry through our contact form, we collect only the information you voluntarily provide (such as your name, email address, and message contents). This information is used exclusively to respond to your question, troubleshoot technical issues, or implement requested calculator improvements. We do not sell, rent, or distribute your email address to marketing third parties.
4. Technical Hosting & Server Logs
Like virtually all web services, our hosting infrastructure provider (Vercel) automatically processes standard HTTP connection logs for security defense, DDoS mitigation, and uptime reliability. These logs may record basic request metadata such as your IP address, browser user-agent, requested page URI, and request timestamp. These logs are maintained strictly for technical maintenance, threat detection, and operational integrity.
5. External Links & Third-Party Platforms
Our educational articles and calculator documentation may contain references or hyperlinks to external websites, such as the Interactive Advertising Bureau (IAB), Media Rating Council (MRC), or official ad platform documentation. We are not responsible for the privacy practices, content, or data policies of these external sites. We encourage you to review their respective privacy policies when visiting them.
7. Your Rights & Privacy Inquiries
Depending on your jurisdiction, you have the right to request access to or deletion of any personal communications you have sent to us. Because we do not require user accounts or store calculator data, we do not maintain persistent records linking your identity to your site usage. For any questions regarding this Privacy Policy, please contact us directly at hello@cpmcalculatorpro.org.
