Privacy Policy
Effective Date: January 1, 2026 • Full Compliance with GDPR, CCPA, and Google AdSense
1. Local Client-Side Calculation
MailCostCalc executes calculations directly inside your browser's JavaScript environment. When you adjust monthly email volume sliders, test dedicated IP add-ons, or estimate annual prepayments, none of these figures are transmitted across the network, stored in databases, or logged on remote servers.
2. Google AdSense & Third-Party Cookies
We may display non-intrusive advertisements served by Google AdSense to sustain free hosting and maintenance:
- Third-party vendors, including Google, utilize cookies to serve advertisements based on previous website interactions.
- Google’s advertising cookies enable personalized ad delivery across the Google Display Network.
- Visitors may manage or opt out of personalized ad targeting by visiting Google Ads Settings.
3. California Consumer Privacy Act (CCPA)
Under the CCPA, California residents possess rights regarding the collection, disclosure, and deletion of personal data. Because MailCostCalc does not collect or sell consumer data, your information remains unmonetized and private by default.
4. European General Data Protection Regulation (GDPR)
For visitors residing in the European Economic Area (EEA), we do not process personal data without explicit consent. Cloudflare edge-routing logs operate strictly for network security and traffic optimization.
