These terms govern your use of Aurelius SDR ("the Service") at aureliussdr.com.
Aurelius SDR monitors DNS-based email authentication and reputation signals (SPF, DKIM, DMARC, MX, DNS blacklists) for domains you register with your account, and provides free one-off checking tools. Checks are performed against public DNS data.
You may monitor domains you own or are authorized to manage. You may not use the Service to harass, to probe domains at abusive rates, or to resell results without permission. We may suspend accounts that abuse the Service.
The Free plan is free indefinitely. Pro is billed monthly by our payment processor (Polar); you can cancel anytime and keep access until the end of the billing period. See our refund policy.
The Service is provided "as is". DNS data, blacklist listings and grades are informational and depend on third-party sources; we do not guarantee accuracy, completeness, or that following our recommendations will improve deliverability. To the maximum extent permitted by law, our liability is limited to the amount you paid us in the preceding 3 months.
You may delete your account at any time by contacting support@aureliussdr.com. We may terminate accounts violating these terms.
We may update these terms; continued use after changes constitutes acceptance. Material changes will be noted on this page.
