Terms of Service & Subscription Agreement

Last Updated: September 2026
Company Entity: AIURSOFT LIMITED (Hong Kong)

Welcome to Aiursoft. We are dedicated to bringing the spirit of open-source and free software to every enterprise and individual.

These Terms of Service ("Terms") govern your access to and use of the Aiursoft website, products, and subscription services, including but not limited to Aiursoft Substratum (Core, Startup, and Enterprise plans) (collectively, the "Services"). By registering for an account or purchasing a subscription, you agree to be bound by these Terms.

1. The Nature of Our Services

Aiursoft provides enterprise IT infrastructure solutions built upon open-source technologies (e.g., Linux, Nextcloud, Mailcow, Authentik, GitLab).

  • The Software is Free: The underlying open-source codes are subject to their respective licenses (e.g., MIT, GPL). You are free to inspect, modify, and distribute the code as permitted by those licenses.
  • The Service is Commercial: What you are purchasing from Aiursoft is the hosting, automated deployment, maintenance, priority support, and enterprise integration of these tools.

2. Plan Distinctions & Responsibilities

We offer different tiers of deployment to suit your business needs:

  • Cloud-Hosted Plans (e.g., Core): Aiursoft hosts the infrastructure on our secured servers. We are responsible for server uptime, standard backups, and basic network security.
  • On-Premise Plans (e.g., Startup, Custom Enterprise): The software is deployed on your local servers or private cloud. You retain absolute physical control and ownership of your data ("Own Your Data"). Consequently, you are solely responsible for your underlying hardware, local network security, physical access control, and disaster recovery backups. Aiursoft's responsibility is limited to software-level maintenance, container updates, and technical support as defined in your plan.

Enterprise services do not automatically extend an operating-system release's published security-update lifecycle. AnduinOS 2.0 standard support ends in April 2031. Your service agreement specifies included systems, supported devices, management integrations, maintenance responsibilities, and service duration.

Where a plan includes 7×24 on-call support, this means incident intake and escalation. The service agreement defines incident severity, response targets, support channels, maintenance windows, and exclusions. It does not guarantee immediate resolution or uninterrupted availability.

An isolated deployment requires local packages, models, identity services, and other dependencies. Hosted email, cloud management, and external model APIs require connectivity and are outside the isolated environment. These services and their data flows must be agreed before activation.

3. Subscription, Billing, and Payments

To ensure uninterrupted service, our commercial plans operate on a recurring subscription basis.

  • Per-User Billing: Subscription fees are calculated based on the number of active users/accounts managed within your Aiursoft Identity Gateway per billing cycle.
  • Payment Processing: All payments are securely processed by our third-party payment gateway, Stripe. Aiursoft does not collect, process, or store your full credit card information on our servers.
  • Automatic Renewal: Your subscription will automatically renew at the end of each billing cycle (monthly or annually) unless you cancel it prior to the renewal date. You authorize us (via Stripe) to charge the applicable subscription fees to your payment method on file.
  • Taxes: All fees are exclusive of applicable taxes, levies, or duties imposed by taxing authorities, and you shall be responsible for payment of all such taxes.

4. Cancellation and Refund Policy

  • How to Cancel: You may cancel your subscription at any time through your Aiursoft Billing Dashboard or by contacting our support team.
  • Effect of Cancellation: If you cancel your subscription, the cancellation will take effect at the end of your current paid billing cycle. You will retain full access to the Services until that cycle concludes.

No Pro-Rated Refunds: We do not provide refunds or credits for any partial-month subscription periods, or for user accounts that were provisioned but remained inactive.

One-Time Setup Fees: For On-Premise plans requiring a One-Time Setup Fee, this fee covers the manual labor of our architects (e.g., network configuration, Docker deployment, Yubikey integration). Setup fees are strictly non-refundable once the deployment and configuration process has commenced.

5. Hardware Purchases (Third-Party)

Certain features, such as offline AI Knowledge Base construction or hardware-based Zero Trust authentication, may require physical hardware (e.g., NVIDIA GPUs, YubiKeys). Unless explicitly stated in a custom enterprise contract, you are responsible for procuring this hardware directly from the respective manufacturers. Aiursoft acts solely as the software integration provider.

6. Acceptable Use Policy

You agree not to misuse the Services or help anyone else to do so. You must not:

  • Use the Services to conduct any illegal, fraudulent, or malicious activities.
  • Attempt to bypass or compromise any security measure implemented by Aiursoft on Cloud-Hosted plans.
  • Use our Cloud-Hosted email services (Mailcow) to send unsolicited spam or conduct phishing campaigns. Violation of this rule will result in immediate account termination without refund.

7. Intellectual Property

Aiursoft software, including deployment scripts and Template orchestration code, is provided under its published open-source licenses. Copyright ownership does not restrict the rights granted by those licenses. Third-party software retains its respective licenses. Aiursoft names, logos, and branding are separate from software licensing; modified distributions must not be presented as official products.

8. Limitation of Liability

To the maximum extent permitted by law, Aiursoft Limited shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, whether incurred directly or indirectly, or any loss of data, use, goodwill, or other intangible losses, resulting from:

  • Your access to or use of or inability to access or use the Services.
  • Any unauthorized access to your on-premise servers (for Startup/Enterprise plans).
  • Data loss due to hardware failure on your self-hosted infrastructure.

In no event shall Aiursoft's aggregate liability for all claims related to the services exceed the total amount paid by you to Aiursoft for the specific service in the twelve (12) months preceding the claim.

9. Modifications to the Terms

We may revise these Terms from time to time to better reflect changes to the law, new regulatory requirements, or improvements made to our Services. If an update affects your use of the Services or your legal rights as a user of our Services, we’ll notify you prior to the update's effective date by sending an email to the account owner.

10. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the Hong Kong Special Administrative Region, without regard to its conflict of law provisions.
