The following capitalized terms have the meanings given below. Other terms may be defined elsewhere in these Terms.


2. Acceptance of Terms

2.1 How you accept

You accept these Terms by any of the following actions:

2.2 Corporate acceptance

If you accept these Terms on behalf of a company, organization, or other legal entity, you represent and warrant that (a) you have full legal authority to bind that entity to this Agreement, and (b) you have read and understood these Terms. If you lack such authority, do not install or use the Software.

2.3 Changes to these Terms

Semaphore UI reserves the right, at its sole discretion, to modify, update, or replace these Terms (and any incorporated Policies) at any time. Such modifications shall be effective and legally binding on all existing and future Users as follows:


3. Product Tiers and Applicable Terms

Semaphore UI is distributed in three tiers. The table below summarizes which legal frameworks apply to each tier:

Feature Community Pro Enterprise
License type MIT (open source) Commercial Commercial
These Terms apply Yes (website/portal use) Yes Yes
Subscription Agreement No Yes Yes
Support obligation Community only Per plan Per SLA
Confidentiality clause No Standard Mutual / extended

3.1 Community Edition

The Community Edition is open-source software licensed under the MIT License. You may use, copy, modify, merge, publish, distribute, sublicense, and sell copies of the Community Edition in accordance with the MIT License. These Terms apply to your use of the Portal and any hosted services associated with Community Edition accounts. The MIT License governs use of the Community Edition source code itself.

3.2 Pro and Enterprise Editions

The Pro and Enterprise Editions contain proprietary features not available under the MIT License. Use of the Pro or Enterprise Edition requires a valid paid subscription and is governed by both these Terms and the Subscription Agreement. In the event of a conflict between these Terms and the Subscription Agreement, the Subscription Agreement controls with respect to subscription-specific matters (fees, SLAs, support).

3.3 No combination of editions

You may not use Pro or Enterprise Edition features without a valid subscription, regardless of how the Software was obtained. Enabling paid features on an unlicensed installation is a material breach of these Terms of Service.


4. License Grant

4.1 Community Edition license

Subject to the MIT License (https://opensource.org/licenses/MIT), we grant you a perpetual, worldwide, royalty-free, non-exclusive license to use, copy, modify, and distribute the Community Edition source code and binaries. The MIT License text is included in the Community Edition distribution.

4.2 Pro and Enterprise Edition license

Subject to your compliance with these Terms, timely payment of all fees, and the terms of the Subscription Agreement, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to:

4.3 License restrictions

Except as expressly permitted in these Terms or the applicable open-source license, you must not:

4.4 Open-source components

If the Software includes third-party open-source components, list of such components and their licenses shall be made available in https://github.com/semaphoreui/semaphore/blob/develop/THIRD-PARTY-LICENSES.md. Those components are licensed under their respective open-source licenses, not under these Terms. Nothing in these Terms limits your rights under, or grants you rights that supersede, the terms of any applicable open-source license.


5. Acceptable Use Policy

5.1 Permitted uses

You may use the Software to manage and automate your own infrastructure, run automation jobs on systems you own or are authorized to administer, and integrate the Software with your internal DevOps workflows.

5.2 Prohibited uses

You must not use the Software, directly or indirectly, to:

5.3 Responsibility for Automation Content

You are solely responsible for all Automation Content you create, upload, schedule, or execute through the Software. You represent and warrant that your Automation Content does not violate any applicable law or third-party rights. We are not responsible for reviewing, monitoring, or evaluating any Automation Content.

5.4 Suspension for AUP violations

We may suspend or terminate your access to the Portal or license keys immediately and without notice if we reasonably believe you are violating this Acceptable Use Policy, and such suspension or termination shall not give rise to any refund obligation.


6. Self-Hosted Deployment Responsibilities

6.1 Customer’s responsibility for the instance

Because the Software operates as a Self-Hosted Instance on Customer’s infrastructure, Customer bears full and exclusive responsibility for:

6.2 No access by Semaphore UI

Semaphore UI does not have access to any Self-Hosted Instance, its database, its stored Credentials, or any Automation Content. All data stored within a Self-Hosted Instance resides entirely on Customer’s infrastructure and remains under Customer’s sole control. Customer acknowledges that Semaphore UI is technically unable to provide data recovery, remote configuration, or remediation for Self-Hosted Instances.

6.3 License checks

Pro and Enterprise Editions may periodically contact Semaphore UI servers to validate the license key, and check for updates.

6.4 Air-gapped deployments

Customers operating Self-Hosted Instances in air-gapped or offline environments must arrange for periodic license validation by alternative means as described in the Documentation and upon request of Semaphore provide proofs if permitted use and license validity. Semaphore UI is not responsible for feature degradation resulting from an inability to perform online license validation in air-gapped environments.


7. Credentials and Secrets

7.1 Customer’s responsibility for Credentials

The Software includes a Key Store feature that encrypts and stores Credentials (SSH keys, API tokens, passwords) on the Self-Hosted Instance. Customer is solely responsible for:

7.2 No Semaphore UI access to Credentials

Semaphore UI has no access to Credentials stored in any Self-Hosted Instance. Semaphore UI does not transmit, log, or process Credentials stored in Self-Hosted Instances. Customer assumes all risk associated with the storage and use of Credentials within the Software.

7.3 Credential exposure disclaimer

Semaphore UI expressly disclaims all liability for any unauthorized disclosure, theft, compromise, or misuse of Credentials resulting from: (a) vulnerabilities in Customer’s infrastructure; (b) misconfiguration of the Self-Hosted Instance or Key Store; © insider threats or unauthorized access to Customer’s systems; (d) Customer’s failure to apply security updates; or (e) any other cause within Customer’s control or environment.


8. Infrastructure and Automation Liability

8.1 Customer’s responsibility for automation outcomes

The Software executes Automation Content (playbooks, scripts, Terraform plans, shell commands, etc.) against infrastructure designated by Customer. Customer is solely responsible for:

8.2 Disclaimer of infrastructure liability

SEMAPHORE UI EXPRESSLY DISCLAIMS ALL LIABILITY FOR ANY DAMAGE TO CUSTOMER’S INFRASTRUCTURE OR THIRD-PARTY SYSTEMS ARISING FROM OR RELATED TO THE EXECUTION OF AUTOMATION CONTENT THROUGH THE SOFTWARE. THIS INCLUDES, WITHOUT LIMITATION, DAMAGE RESULTING FROM:

8.3 No warranty on automation outcomes

The Software is a tool for executing Automation Content defined by Customer. Semaphore UI makes no representation or warranty that executing Automation Content through the Software will produce the intended infrastructure outcomes. Customer assumes all risk associated with the results of automation jobs.


9. Accounts, Registration, and Security

9.1 Portal accounts

To access certain Portal features (license management, billing), you must create an account. You agree to provide accurate, current, and complete registration information and to update it as necessary to keep it accurate.

9.2 Account security

You are responsible for maintaining the confidentiality of your Portal account credentials. You agree to:

9.3 Organization accounts

If your account is associated with an organization, the organization’s administrator may have access to your account and may restrict, suspend, or terminate your access. We are not liable for actions taken by organization administrators in accordance with their organization’s internal policies.

9.4 Account suspension

We may suspend or terminate your Portal account if we determine, in our reasonable judgment, that you have violated these Terms, your account has been compromised, or continued access poses a security or legal risk.


10. Subscriptions, Billing, and Payment

10.1 Subscription terms

Use of the Pro or Enterprise Edition requires a paid subscription as set out in the Subscription Agreement and/or the applicable Order Form.

10.2 Fees and invoicing

Fees are as stated in the Order Form or on our pricing page at the time of purchase. Unless the Order Form specifies otherwise, we will invoice Customer in advance for each Subscription Term. All invoices are payable within thirty (30) days of the invoice date unless another date has been agreed upon in the Subscription Agreement or the Order Form.

10.3 Auto-renewal

Unless either party provides written notice of non-renewal at least thirty (30) days before the end of the current Subscription Term, the subscription will automatically renew for a successive term of equal duration at the then-current list price. We will send a renewal reminder no less than forty-five (45) days before the renewal date.

10.4 Price changes

We may change our subscription fees upon renewal. We will provide at least sixty (60) days’ prior written notice of any fee increase before it takes effect at renewal.

10.5 Taxes

All fees are exclusive of applicable taxes (VAT, sales tax, withholding tax, etc.), which are the sole responsibility of Customer. If we are required by law to collect such taxes, they will be added to the invoice.

10.6 Late payments

Overdue invoices accrue interest at the rate of 1.5% per month (or the maximum rate permitted by law, whichever is lower), compounded monthly, from the due date. We reserve the right to suspend access to license keys and the Portal for accounts with invoices overdue by more than fifteen (15) days, after providing seven (7) days’ written notice.

10.7 Refunds

Refund eligibility is governed by our Refund Policy available at semaphoreui.com/legal/refund-policy. Annual subscriptions may be refunded in full within thirty (30) days of the initial purchase if Customer has not downloaded the license key or activated a Pro/Enterprise Instance. No refunds are available after this period, except as required by applicable law or as explicitly stated in the Subscription Agreement.


11. Intellectual Property

11.1 Semaphore UI IP

As between the parties, Semaphore UI retains all right, title, and interest in and to:

11.2 Community Edition IP

The Community Edition source code is made available under the MIT License. The MIT License governs your rights with respect to the Community Edition code. These Terms do not restrict rights already granted by the MIT License, but they do apply to your use of the Portal and commercial services.

11.3 Customer IP and Automation Content

Customer retains all right, title, and interest in and to all Automation Content. We claim no ownership of your playbooks, scripts, Terraform configurations, inventory data, variable files, or any other Customer data processed by the Software. You grant us no license to your Automation Content except as strictly necessary to perform the Portal services (e.g., storing and delivering your license key). For the avoidance of doubt, we do not access, analyze, or use your Automation Content for any purpose other than providing the Software and Portal services you have contracted for.

11.4 Feedback

If you provide us with suggestions, ideas, enhancement requests, recommendations, or other feedback about the Software (“Feedback”), you grant us a perpetual, irrevocable, worldwide, royalty-free license to use, incorporate, and commercialize that Feedback without restriction or obligation to you. You represent that you are entitled to grant this license.

11.5 Trademark use

Nothing in these Terms grants you the right to use the Semaphore UI name, logo, or trademarks in any manner, except as strictly necessary to describe your use of the Software (e.g., “Powered by Semaphore UI” with our prior written consent). All other trademark use requires our prior written approval.


12. Privacy and Data Processing

12.1 Privacy Policy

Your use of the Portal is subject to our Privacy Policy, available at semaphoreui.com/privacy/policy, which is incorporated into these Terms by reference. The Privacy Policy describes how we collect, use, disclose, and protect personal data submitted through the Portal.

12.2 Data on Self-Hosted Instances

All data stored within a Self-Hosted Instance — including Automation Content, Credentials, audit logs, and task execution history — resides entirely on Customer’s infrastructure. Semaphore UI does not process, access, or control such data. Customer is the data controller for all personal data processed within a Self-Hosted Instance and is solely responsible for compliance with all applicable data protection laws (including GDPR, where applicable).

12.3 Portal data

Data submitted to the Portal (account information, billing data, license activation records) is processed by Semaphore UI as described in the Privacy Policy. For customers subject to GDPR, we will execute a Data Processing Agreement upon written request.


13. Confidentiality

13.1 Confidential Information

“Confidential Information” means any non-public technical, business, financial, or operational information disclosed by one party (“Disclosing Party”) to the other (“Receiving Party”) that is designated as confidential or that reasonably should be understood to be confidential given the nature of the information. Confidential Information includes, without limitation: source code, product roadmaps, pricing not publicly available, security vulnerabilities, and the terms of any Order Form.

13.2 Obligations

Each party agrees to: (a) hold the other party’s Confidential Information in strict confidence using at least the same degree of care it uses to protect its own confidential information, but in no event less than reasonable care; (b) not disclose Confidential Information to any third party without the prior written consent of the Disclosing Party, except to employees, contractors, or advisors who have a need to know and are bound by confidentiality obligations no less restrictive than these; and © use Confidential Information only for purposes of exercising rights or performing obligations under this Agreement.

13.3 Exceptions

Confidentiality obligations do not apply to information that: (a) is or becomes publicly known through no breach of these Terms; (b) was rightfully known to the Receiving Party before disclosure; © is independently developed by the Receiving Party without use of Confidential Information; or (d) is required to be disclosed by law, regulation, or court order, provided the Receiving Party gives prompt written notice to the Disclosing Party (to the extent permitted by law) and cooperates in seeking a protective order.

13.4 Duration

Confidentiality obligations survive termination of this Agreement for a period of three (3) years, except with respect to trade secrets, for which obligations survive indefinitely.


14. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW:

Some jurisdictions do not allow the exclusion of implied warranties, so some of the above exclusions may not apply to you. In such cases, our warranties are limited to the minimum scope permitted by applicable law.


15. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW:

Some jurisdictions do not allow the limitation of liability for certain types of damages. To the extent such limitations are prohibited, our liability is limited to the minimum amount permitted by applicable law.

The parties acknowledge that the limitations of liability in this Section reflect a reasonable allocation of risk and form an essential basis of the bargain between the parties. Semaphore UI would not have entered into this Agreement without these limitations.


16. Indemnification

16.1 Customer indemnification

You agree to defend, indemnify, and hold harmless Semaphore UI and its affiliates, directors, officers, employees, agents, and licensors from and against any and all claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys’ fees) arising out of or in any way connected with:

16.2 Indemnification procedure

We will: (a) promptly notify you in writing of any indemnifiable claim; (b) give you sole control of the defense and settlement of the claim (provided that you may not settle any claim without our prior written consent if the settlement imposes obligations on us); and © provide you with reasonable cooperation and information. You will not be relieved of your indemnification obligations if we fail to provide timely notice, except to the extent you are materially prejudiced by such failure.


17. Third-Party Services and Integrations

The Software integrates with third-party tools and services (Ansible, Terraform, OpenTofu, PowerShell, Git hosting providers, notification services, etc.). These third-party tools and services are subject to their own terms of service and are not governed by this Agreement. Semaphore UI is not responsible for the availability, functionality, or behavior of any third-party tool or service, and does not warrant that any integration will function as expected with any particular third-party version or configuration.

The Portal may contain links to third-party websites. We do not endorse and are not responsible for the content, privacy practices, or services of linked third-party websites. You access such websites at your own risk.
