Your Privacy, Our PromiseAt the heart of our service is a simple commitment: your trust matters. We are dedicated to protecting your privacy every step of the way.

  • We treat your personal information with the utmost care and confidentiality.
  • We never sell or rent your data to anyone, for any reason.
  • We collect and store only the minimum data required to deliver and improve our service.

You are always in control of your information. If you have questions or concerns, our team is here to help.

1. Information We Collect

At MailCheckr, we are committed to transparency regarding the information we collect and how it is used. Our data collection practices are designed to respect your privacy while enabling us to deliver, secure, and improve our services. We collect information in several ways, both directly and indirectly, and we strive to ensure that you are always aware of what data is being gathered.

Automatically Collected Data: When you visit our website or use our services, certain information is collected automatically. This includes technical data such as your IP address, browser type and version, operating system, device type, screen resolution, language preferences, and referring URLs. We also collect information about your interactions with our site, such as the pages you view, the time and date of your visits, the amount of time spent on each page, and the links you click. This data helps us understand how users interact with our platform and allows us to optimize the user experience, troubleshoot issues, and maintain the security of our systems.

Cookies and Tracking Technologies: We use cookies, web beacons, and similar tracking technologies to enhance your experience, remember your preferences, and analyze site traffic. Cookies are small text files stored on your device that help us recognize repeat visitors and personalize content. While most cookies are essential for the operation of our site, some are used for analytics purposes. You can manage your cookie preferences through your browser settings, but please note that disabling cookies may affect the functionality of certain features.

Voluntarily Provided Data: In addition to automatically collected data, we also collect information that you voluntarily provide to us. This may include your email address when you use our email verification tool, submit a contact form, or communicate with our support team. We may also collect additional information you choose to share, such as feedback, survey responses, or other correspondence. We do not require users to create accounts or provide personal profiles, and we do not request sensitive personal information such as government identification numbers, financial data, or health records.

Aggregated and Anonymized Data: To better understand usage patterns and improve our services, we may aggregate and anonymize data collected from users. This process removes personal identifiers, ensuring that the resulting data cannot be used to identify any individual. Aggregated data is used for statistical analysis, system performance monitoring, and service enhancements.

Third-Party Data: We may receive information from third-party service providers, such as analytics platforms, CAPTCHA providers, or infrastructure partners. These third parties may collect data in accordance with their own privacy policies, and we encourage you to review those policies for more information. We use third-party data solely to enhance the security, reliability, and performance of our services.

  • Technical data (IP address, browser, device, OS, etc.) is used for security, analytics, and troubleshooting.
  • Usage data (pages viewed, time spent, actions taken) helps us improve our site and understand user needs.
  • Contact data (email, support messages) is used only to respond to your inquiries or provide requested services.
  • Aggregated and anonymized data is never used to identify individuals and is not shared outside our organization except as part of statistical reports.

We do not knowingly collect data from children under the age of 16. If you believe that a minor has provided us with personal information without parental consent, please contact us immediately so we can take appropriate action. We also do not collect or process sensitive categories of personal data, such as racial or ethnic origin, political opinions, religious beliefs, or biometric data.

Our commitment to data minimization means we only collect the information necessary to provide and improve our services. We regularly review our data collection practices to ensure compliance with applicable laws and industry standards.

When data is no longer needed, we securely delete or anonymize it in accordance with industry best practices. We do not retain verified email addresses, queries, or user data beyond what is necessary for the operation and security of our service.

4. Data Sharing and Disclosure

We are committed to maintaining the confidentiality of your personal data. We do not sell, rent, or share your personal information with third parties for their own marketing or commercial purposes. Data sharing is limited to the following circumstances:

  • Service Providers: We may share data with trusted service providers who assist us in operating our infrastructure, hosting our website, processing analytics, or delivering communications. These providers are contractually obligated to protect your data and may only use it as necessary to perform their services for us.
