Privacy Policy

Last Update: April 2026

This Privacy Policy explains how Email-Check.app collects, uses, protects, and deletes personal information when you visit the site, create an account, use the email validation API, contact support, or pay for services.

Information we collect

  • Account information such as name, email address, company, login details, and account settings.
  • Billing information such as plan, invoices, payment status, tax details, and transaction identifiers.
  • API usage information such as request volume, timestamps, endpoint usage, error logs, and account limits.
  • Validation request data needed to return syntax, domain, MX, SMTP, and risk signals.
  • Support and sales messages you send to us, including attachments and contact details.
  • Device and browser data such as IP address, user agent, referrer, cookie identifiers, and approximate location.

How we use information

  • Provide, secure, monitor, and improve the Email-Check.app website, account area, and API.
  • Process email validation requests and return validation results.
  • Handle billing, invoices, payment events, refunds, and account notices.
  • Respond to support, sales, security, privacy, and legal requests.
  • Detect abuse, fraud, spam, credential misuse, and service attacks.
  • Send product, service, and operational messages when permitted by law and account settings.

Validation data

Email validation requires processing the email address or list you submit. We use that data to return the requested validation result, protect the service, troubleshoot issues, and maintain billing and usage records. We do not sell submitted email addresses, use them to create marketing lists, or use them for unrelated advertising.

Cookies and analytics

We use cookies and similar technologies for authentication, preferences, analytics, security, and performance monitoring. Learn more in our Cookie Policy.

Service providers

We use service providers for hosting, infrastructure, analytics, payments, customer support, email delivery, fraud prevention, and monitoring. These providers may process personal information only as needed to provide services to Email-Check.app and under their own security and privacy commitments.

Retention

We retain information for as long as needed to provide the service, comply with legal and billing obligations, resolve disputes, prevent abuse, and maintain security. When data is no longer needed, we delete, anonymize, or aggregate it where practical.

Your privacy rights

Depending on where you live, you may have rights to access, correct, delete, export, restrict, or object to certain processing of your personal information. California residents may also have rights to know, delete, correct, limit certain sensitive data use, and opt out of sale or sharing where those rules apply. We do not sell personal information.

To exercise privacy rights, use the contact form or follow the steps on Delete Your Data. We may ask you to verify account ownership before completing the request.

Security

We use technical and organizational safeguards to protect personal information. No internet service can guarantee perfect security, but we work to reduce risk through access control, encryption, monitoring, dependency review, and operational controls. Learn more on our Security page.

Children

Email-Check.app is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, contact us so we can review and remove it.

Changes to this policy

We may update this policy as our service, providers, or legal obligations change. The updated date at the top of this page shows when the policy was last refreshed.
