1. Affirmative declaration: We do not sell personal data
Secuno LLC does NOT sell, rent, monetize, release, disclose, disseminate, make available, transfer, or otherwise communicate personal information to any third party for monetary or other valuable consideration.
Furthermore, MailCheckup does NOT "share" personal information for cross-context behavioral advertising (retargeting) as defined under the California Consumer Privacy Act (CCPA) as amended by the California Privacy Rights Act (CPRA).
2. Why MailCheckup displays no "Do Not Sell" banners
Many commercial websites feature prominent "Do Not Sell or Share My Personal Information" modal banners. Under California Civil Code § 1798.135, such opt-out mechanisms are mandated exclusively for entities that actively engage in selling or sharing consumer information.
Because MailCheckup maintains a permanent Zero Data Resale Architecture and never engages in commercial behavioral ad sharing, an opt-out banner is legally inapplicable. Your personal data is protected by default without requiring manual opt-out toggling.
3. Global Privacy Control (GPC) signal detection
MailCheckup recognizes and honors Global Privacy Control (GPC) signals. When our web servers detect the Sec-GPC: 1 HTTP request header transmitted by privacy-focused user agents (such as Brave, Firefox, or DuckDuckGo Privacy Essentials), our systems confirm that no tracking or secondary sharing takes place.
4. Notification preferences vs. marketing communications
We respect your inbox. MailCheckup does NOT conduct unsolicited outbound commercial marketing email campaigns. Communications from our platform are strictly transactional and operational:
- Payment confirmation receipts and downloadable invoices (number MCU-YYYYMMDD-####) issued by Secuno LLC.
- Verification job completion notices and automated export links.
- Critical security advisories (e.g. API key generation or password resets).
5. Third-party ad trackers & profiling exclusion
We do not embed third-party advertising cookies, retargeting pixels, or behavioral profiling telemetry on our websites. Loading mailcheckup.net will never result in retargeted advertising on social media platforms or search engines.

6. Frequently asked privacy choices questions
Does MailCheckup sell personal data under California law?
No. Under the California Consumer Privacy Act (CCPA) as amended by the CPRA, 'selling' is defined broadly to include transferring personal information to a third party for monetary or other valuable consideration. Secuno LLC does not engage in selling or sharing personal data under any circumstances.
Why isn't there an interactive 'Do Not Sell My Info' toggle button on this page?
Interactive opt-out toggles are legally required only for platforms that actively sell personal information or share it with third-party behavioral advertising networks. Because MailCheckup does not sell, broker, or share personal data, an opt-out toggle is legally inapplicable and unnecessary.
Does MailCheckup respect the Global Privacy Control (GPC) signal?
Yes. If your web browser or browser extension transmits the Global Privacy Control header (Sec-GPC: 1), our systems acknowledge this signal. Because we already enforce a complete no-sale and zero-tracking baseline, your privacy preferences are natively respected.
Can I opt out of receiving transactional account emails?
Transactional emails (such as Stripe billing receipts, password reset links, and critical API security notifications) are essential to the performance of our contract with you. You cannot opt out of these essential administrative notices while maintaining an active workspace.
Does MailCheckup allow third parties to collect personal data on its website?
No. We do not permit third-party advertising networks, data aggregators, or behavioral tracking companies to collect personal data or cookies from visitors browsing mailcheckup.net or cp.mailcheckup.net.
How can I submit an opt-out inquiry if I have additional questions?
You can email our corporate legal desk at privacy@mailcheckup.net. Our privacy engineers will confirm your account status and verify that no secondary sharing exists.
