The Service, excluding open-source components, is owned by DMARCguard and protected by intellectual property laws. The DMARCguard name, logo, and branding are our trademarks. The open-source core of the project is licensed separately under its published license and is not subject to these proprietary IP terms.

6.2 Your Data

You retain all rights to the data you provide to the Service, including DMARC/TLS-RPT reports and domain configurations. By using the Service, you grant us a limited license to process, store, and display your data solely for the purpose of providing the Service to you.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, DMARCGUARD AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AND AGENTS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, DATA, USE, OR GOODWILL, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE.

OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE AMOUNT YOU HAVE PAID US IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM.

8. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

We do not warrant that the Service will be uninterrupted, error-free, or that it will detect all email authentication issues. The Service provides monitoring and reporting — it does not guarantee the security or deliverability of your email.

9. Indemnification

  • You may export your data using the Service's export features before termination, or request a data export from us.

11. Governing Law and Disputes

These Terms are governed by and construed in accordance with the laws of the jurisdiction in which DMARCguard is incorporated, without regard to conflict of law principles.

Any disputes arising from these Terms or the Service shall first be attempted to be resolved through good-faith negotiation. If negotiation fails, disputes shall be resolved through binding arbitration or in the courts of the applicable jurisdiction.

12. Modifications to Terms

We may update these Terms from time to time. We will notify you of material changes by posting the updated Terms on this page and updating the "Last updated" date. For significant changes, we will also notify you via email or an in-app notification.
