Terms of Service

1. Acceptance of Terms

These Terms of Service ("Terms") form a binding agreement between you ("you" or "Customer") and A Holdings Company LLC ("ZoneRails," "we," "us," or "our"). They govern your access to and use of the ZoneRails desktop application, the ZoneRails Server, the websites at getzonerails.com and register.getzonerails.com, our APIs, and any related services (collectively, the "Service").

By installing the software, registering for a license, or otherwise using the Service, you accept these Terms. If you do not accept them, do not install, register, or use the Service.

2. Description of Service

ZoneRails is software for planning, deploying, and verifying DNS changes against providers you connect to it — including Cloudflare and Microsoft Active Directory DNS. It is offered as ZoneRails Server, a self-hosted, multi-user server that your team accesses through a web browser. The earlier desktop application for macOS and Windows is discontinued, and these Terms continue to apply to existing installations of it. Either way, ZoneRails operates on your machine or your infrastructure; it reads and writes DNS records on your behalf using API tokens or domain credentials that you supply. We do not store, mirror, or transmit your DNS records to our servers.

3. License to Use the Software

Use of the software (desktop application and ZoneRails Server alike) is also governed by the End-User License Agreement (EULA). In summary, we grant you a personal, non-transferable, non-exclusive, revocable license to install and use ZoneRails on the machines — or, for ZoneRails Server, the server instance and the number of named user seats — you are licensed for, for your own internal business or personal purposes, in accordance with these Terms and the EULA. You may not redistribute, sublicense, or sell the software.

4. Accounts & License Keys

The free Standard tier of ZoneRails Server requires no license key and no registration, and a server on it does not contact our licensing service. On the discontinued desktop application, the free tier requires a license key, bound to the machine that registered it via a non-personal device fingerprint. The Pro and Enterprise tiers may require a billing email and other contact information. A ZoneRails Server license is bound to the server instance and is limited to a stated number of named user seats; a seat is consumed by each enabled user account on your server, and seat limits are enforced when accounts are created or re-enabled. User accounts on a self-hosted ZoneRails Server are created and managed by your own administrators, on your infrastructure.

You are responsible for safeguarding your license key. License keys are personal to you and may not be shared, transferred, or sold without our written consent. We may revoke a license key if we determine, in good faith, that it has been issued in error, fraudulently, or used in violation of these Terms.

5. Fees

The Service is currently provided free of charge for all tiers. Registration may be required for certain tiers, but no fees are payable to use the Service. We may introduce paid tiers, fees, or usage limits in the future. If we do, we will provide at least 30 days' advance notice via email or in-app notice, and the introduction of fees will not apply retroactively to your prior use of the Service. You may decline any future paid tier by continuing to use only the tiers that remain free or by ceasing to use the Service.

6. Your Content, Tokens & Credentials

You retain ownership of all DNS records, API tokens, AD credentials, ticket numbers, change notes, audit logs, and any other content you process through ZoneRails ("Your Content"). We do not collect or store Your Content on our servers; it lives on your device and on the systems of the providers you connect to (e.g., Cloudflare, your AD domain controllers).

You represent and warrant that you have the necessary rights and authorisations to operate on the DNS zones and credentials you connect to ZoneRails, and that your use of the Service does not violate any agreement you have with a DNS provider or your employer.

7. Acceptable Use

You may not use the Service to:

• violate any law, regulation, or third-party right (including intellectual property and privacy rights);
• attack, disrupt, probe, or otherwise interfere with our infrastructure, license-validation systems, or any third-party DNS provider;
• circumvent or attempt to circumvent licensing, feature gates, machine binding, or access controls;
• reverse-engineer, decompile, or disassemble the software, except to the limited extent expressly permitted by law;
• resell, sublicense, or operate the Service as a managed service to third parties without a separate written agreement; or
• use the Service to manage DNS or systems you are not authorised to operate.

7.5. Production Use & Change Management

ZoneRails is designed to deploy real DNS changes against the providers you connect to it, including in production environments. You acknowledge that DNS changes can cause service outages, email delivery failures, certificate validation failures, and other significant business impact, and that misconfigured or mistimed changes may be difficult to reverse before propagation completes.

You are solely responsible for: (a) verifying that you are authorised to operate on the zones and credentials you connect to ZoneRails; (b) testing changes in a non-production environment where appropriate; (c) ensuring you have an appropriate change window and rollback plan before deploying to production; (d) maintaining your own backups of zone state; and (e) verifying changes after deployment. The planning, diff, and verification features in ZoneRails are intended to assist your change-management practices, not to replace them.

8. Third-Party Services

ZoneRails interoperates with third-party services that you choose to connect, including but not limited to Cloudflare and Active Directory DNS. Your use of those services is governed by their own terms, and we are not responsible for their availability, accuracy, or behaviour.

We use third-party providers for limited operational purposes — transactional email (Gmail / Mailgun) and email delivery for license keys. See our Privacy Policy for details.

9. Intellectual Property

The Service, including all software, documentation, branding, and content (other than Your Content), is owned by A Holdings Company LLC or its licensors and is protected by copyright, trademark, and other intellectual-property laws. Except for the limited license expressly granted by the EULA, no other rights are granted by these Terms.

10. Privacy

Our collection and use of personal information is described in the Privacy Policy, which is incorporated into these Terms by reference.

11. Termination

You may stop using the Service at any time and uninstall the software. We may suspend or terminate your access to the Service at any time, with or without notice, if we reasonably believe you have violated these Terms, the EULA, or applicable law, or to protect the security or integrity of the Service. On termination, the licenses granted to you cease and you must stop using the Service.

The following provisions survive termination: 6 (Your Content), 7.5 (Production Use & Change Management), 9 (Intellectual Property), 12 (Disclaimer), 13 (Limitation of Liability), 14 (Indemnification), 16 (Governing Law), and 17 (Contact).

12. Disclaimer of Warranties

THE SERVICE, THE SOFTWARE, AND ALL CONTENT, FEATURES, GUARDRAILS, VALIDATION, VERIFICATION, ROLLBACK, AND OTHER FUNCTIONS MADE AVAILABLE THROUGH THEM ARE PROVIDED "AS IS," "AS AVAILABLE," AND "WITH ALL FAULTS," WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, A HOLDINGS COMPANY LLC AND ITS MEMBERS, MANAGERS, OFFICERS, EMPLOYEES, CONTRACTORS, LICENSORS, AND SUPPLIERS (COLLECTIVELY, THE "COMPANY PARTIES") DISCLAIM ALL WARRANTIES, CONDITIONS, AND REPRESENTATIONS, WHETHER EXPRESS, IMPLIED, STATUTORY, OR ARISING FROM COURSE OF DEALING, COURSE OF PERFORMANCE, OR USAGE OF TRADE, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, QUIET ENJOYMENT, ACCURACY, COMPLETENESS, RELIABILITY, AVAILABILITY, SECURITY, OR SYSTEM INTEGRATION.

No assurance of performance or results. Without limiting the foregoing, the Company Parties make no warranty, representation, or assurance that the Service (a) will meet your requirements or achieve any intended result; (b) will operate without interruption, delay, or error, or that defects will be corrected; (c) will detect, prevent, block, warn of, or reverse any misconfiguration, conflict, drift, outage, or harmful change to your DNS records, load balancers, pools, monitors, tunnels, zones, or any other resource; (d) will correctly verify propagation or health, or that any verification, validation, guardrail, or rollback feature will function as described in any circumstance; (e) will be compatible with, or continue to function against, any third-party provider, API, operating system, or network; or (f) is free of viruses, malicious code, or other harmful components. Any description of the Service's features, including in documentation, release notes, or marketing materials, is for information only and does not create a warranty.

Assumption of risk. You acknowledge that DNS, load balancing, and network configuration are critical infrastructure; that changes made through the Service take effect against live systems operated by third parties; and that such changes may cause service outages, email delivery failures, certificate validation failures, traffic misrouting, data exposure, or other loss that may be difficult or impossible to reverse. You use the Service entirely at your own risk and accept sole responsibility for every change you plan, schedule, approve, override, execute, or roll back through it, and for the outcome of that change. No advice or information, whether oral or written, obtained from the Company Parties or through the Service creates any warranty not expressly stated in these Terms.

Non-excludable rights. Some jurisdictions do not allow the exclusion of certain warranties. To the extent such a warranty cannot lawfully be excluded, it is limited in duration to thirty (30) days from your first use of the Service, and your sole remedy for its breach is as stated in Section 13.

13. Limitation of Liability

Exclusion of damages. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL THE COMPANY PARTIES BE LIABLE TO YOU OR ANY THIRD PARTY FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, BUSINESS, CONTRACTS, GOODWILL, ANTICIPATED SAVINGS, DATA, OR USE; ANY COST OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES; ANY SERVICE INTERRUPTION, DOWNTIME, OR LOSS OF AVAILABILITY OF ANY WEBSITE, APPLICATION, EMAIL, CERTIFICATE, OR NETWORK; ANY UNAUTHORIZED ACCESS TO OR ALTERATION OF YOUR TRANSMISSIONS, RECORDS, OR DATA; OR ANY DAMAGES ARISING FROM THE ACTS OR OMISSIONS OF ANY THIRD-PARTY PROVIDER, IN EACH CASE ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS, HOWEVER CAUSED AND UNDER ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, BREACH OF STATUTORY DUTY, OR OTHERWISE, EVEN IF A COMPANY PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES AND EVEN IF A REMEDY FAILS OF ITS ESSENTIAL PURPOSE.

Cap on liability. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE TOTAL CUMULATIVE LIABILITY OF THE COMPANY PARTIES, TAKEN TOGETHER, FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE FEES YOU ACTUALLY PAID TO A HOLDINGS COMPANY LLC FOR THE SERVICE IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS (USD ). WHERE THE SERVICE IS PROVIDED WITHOUT CHARGE, THE COMPANY PARTIES' TOTAL LIABILITY WILL NOT EXCEED USD . THE EXISTENCE OF MORE THAN ONE CLAIM WILL NOT ENLARGE THIS LIMIT.

Sole and exclusive remedy. Your sole and exclusive remedy for any dissatisfaction with the Service, or for any breach of these Terms by the Company Parties, is to stop using the Service and, where you have paid fees for a current term, to receive a pro-rated refund of prepaid fees for the unexpired portion of that term.

Release. To the maximum extent permitted by applicable law, you release and forever discharge the Company Parties from any and all claims, demands, losses, and liabilities of every kind, known or unknown, arising out of or relating to any change made to any DNS, load balancing, tunnel, or network resource through the Service, or to any outage, loss, or damage resulting from such a change, whether or not the change was planned, validated, verified, or rolled back using features of the Service.

Basis of the bargain. You acknowledge that the disclaimers in Section 12 and the exclusions and limitations in this Section 13 are fundamental elements of the basis of the bargain between you and A Holdings Company LLC; that the Service would not be provided, or would not be provided on these terms or at this price, without them; and that they apply even if any limited remedy fails of its essential purpose.

Non-excludable liability. Nothing in these Terms excludes or limits any liability that cannot be excluded or limited under applicable law, including liability for fraud, fraudulent misrepresentation, or, where required by law, gross negligence or willful misconduct. In such cases the exclusions and limitations above apply to the fullest extent the law allows.

14. Indemnification

You will defend, indemnify, and hold harmless the Company Parties from and against any and all claims, demands, actions, losses, liabilities, damages, judgments, settlements, penalties, fines, costs, and expenses (including reasonable attorneys' fees and costs of investigation) arising out of or relating to: (a) your access to or use of the Service, or any use under your account or license key; (b) any change to any DNS, load balancing, tunnel, or network resource that is planned, scheduled, approved, overridden, executed, or rolled back through the Service, and any outage, loss, or damage suffered by you or any third party as a result; (c) Your Content, tokens, credentials, or the zones, accounts, and providers you connect to the Service, including any lack of authority to operate on them; (d) your violation of these Terms, of any applicable law or regulation, or of any right of a third party; or (e) any dispute between you and a third-party provider. A Holdings Company LLC may assume the exclusive defense and control of any matter subject to indemnification, at your expense, and you will cooperate with that defense. You may not settle any claim that imposes an obligation or admission on a Company Party without its prior written consent.

15. Changes to These Terms

We may update these Terms from time to time. The "Last updated" date at the top reflects the most recent revision. Material changes will be communicated via email or in-app notice. Your continued use of the Service after the effective date of the updated Terms constitutes acceptance.

16. Governing Law & Disputes

Governing law. These Terms, and any dispute or claim arising out of or relating to them or to the Service (including non-contractual claims), are governed by the laws of the State of Michigan, without giving effect to any choice-of-law or conflict-of-laws rule that would apply the law of another jurisdiction. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Jurisdiction and venue. Any action arising out of or relating to these Terms shall be brought exclusively in the state courts of the State of Michigan or the United States District Court for the district of Michigan in which A Holdings Company LLC maintains its principal place of business. You and we irrevocably consent to the personal jurisdiction of, and venue in, those courts and waive any objection based on inconvenient forum. Either party may seek temporary, preliminary, or permanent injunctive relief in any court of competent jurisdiction to protect its intellectual-property rights or confidential information.

Jury trial waiver. To the extent permitted by law, each party knowingly and voluntarily waives any right to a trial by jury in any action arising out of or relating to these Terms.

Limitation period. Except for claims to protect intellectual-property rights or to collect unpaid fees, any claim arising out of or relating to these Terms must be brought within one (1) year after the claim accrues, or it is barred.

Attorneys' fees. In any action to enforce these Terms, the prevailing party is entitled to recover its reasonable attorneys' fees and costs in addition to any other relief awarded.
