Privacy Policy

Last updated: October 2026

1. Information We Collect

When you use Mail Bounce Pro, we may collect the following types of information:

• Email addresses submitted for verification
• Account registration details (name, email, password hash)
• Usage data (number of verifications, timestamps)
• Device and browser information for security purposes

2. Cookies

We use minimal cookies and local browser storage to maintain your session and track your daily verification credits. We do not use advertising or third-party tracking cookies. Cloudflare Turnstile may set cookies for bot protection purposes.

3. Email Verification Data

Email addresses you submit for verification are used solely to perform the requested checks (syntax, MX records, disposable detection, role account detection, and a live SMTP mailbox check against the receiving mail server). Apart from the bulk upload history described below, we do not store verified email addresses permanently on our servers. Verification results may be cached briefly to improve performance.

Bulk upload history. When you run a bulk upload while signed in, the results file (the email addresses from your file and their verification results) is saved to your account so you can download it again from “Your uploads”. It is kept for 24 hours on the Free plan and for 15 days on paid plans, and is then deleted automatically. Only you can see your uploads, we never sell them, and you can delete any upload yourself at any time.

4. Data Usage

We use collected data to:

• Provide and improve the email verification service
• Maintain account security and prevent abuse
• Communicate important service updates
• Enforce our Terms & Conditions

We do not sell, rent, or share your personal data or email lists with third parties.

5. Data Security

All data transmissions are protected with TLS 1.3 encryption. Passwords are hashed and never stored in plain text. We implement rate limiting and bot protection (Cloudflare Turnstile) to prevent unauthorized access. While we take security seriously, no system is 100% secure and we cannot guarantee absolute security.

6. User Rights

You have the right to:

• Access the personal data we hold about you
• Request deletion of your account and associated data
• Opt out of non-essential communications
• Request a copy of your data (data portability)

To exercise any of these rights, contact us at privacy@mailbouncepro.com.

7. Third-Party Services

We use Google DNS API (dns.google) to perform live MX record lookups. This means domain names are sent to Google's DNS servers for resolution. Please review Google's privacy policy for details. We use Cloudflare Turnstile for bot protection — Cloudflare's privacy policy applies to that service.

8. Referral Program Data

If you use the referral program, we store your referral code, the UPI ID you provide for payouts, and a record of which accounts signed up and purchased through your link. Your UPI ID is used only to pay you and is not shown to other users. We do not show you the email addresses of the people you refer.

9. Product and Offer Emails

We send account and service emails (for example sign-in, password reset and payment receipts). If you have a Free account we may also send occasional upgrade or offer emails. When you create an account you can choose, with an optional checkbox, whether to receive product updates and offers. Every offer email contains an unsubscribe link, and you can also write to support@mailbouncepro.com. After you unsubscribe we stop sending offer emails, but we may still send account and service emails. These emails are sent through Resend. We track opens and clicks in offer emails so we can see which offers are useful. We do not sell your email address.
