Terms of Service

1. The software & licensing

• CH-UI core (open source) is licensed under the Apache License 2.0. You may use, modify, and distribute it under those terms, including commercially.
• CH-UI Pro modules are source-available under a commercial license (BSL). Using them in production requires a valid Pro license, purchased under the terms in Section 3.
• The license service at license.ch-ui.com handles Pro license purchases, trials, and license delivery. It is the only hosted service we operate; CH-UI itself always runs on your infrastructure.

2. Self-hosting

• You are responsible for your own deployment, data, backups, security, and legal compliance.
• The software is provided "as is" without warranty (Section 7).

3. Pro licenses & billing

• Purchases & billing. Pro licenses are annual, billed in advance through Stripe, and renew automatically until cancelled. Pricing is shown on our pricing page.
• Delivery. Your license is a signed file emailed to you after purchase. It is verified offline by your deployment; no connection to our servers is required to use it.
• Trials. We may offer time-limited trial licenses. Trial licenses expire automatically and may not be renewed by re-registering.
• Cancellation. You can cancel renewal at any time; your license stays valid until the end of the current license period, after which Pro modules stop being licensed for production use. Fees already paid are non-refundable except where required by law.
• Price changes. We may change prices; changes apply to your next renewal and we'll give reasonable notice.

4. Acceptable use

You agree not to:

• Use CH-UI to violate any law or third-party rights, or to store or process data you are not authorized to handle.
• Attempt to disrupt, overload, gain unauthorized access to, or probe the security of the license service.
• Share, resell, or misrepresent Pro licenses, or circumvent or tamper with license verification.

We may revoke licenses that are obtained or used in material or repeated violation of these terms.

5. Your data & ownership

• Your data is yours. CH-UI runs on your infrastructure; we claim no ownership of, and receive none of, the content you connect, query, or create.
• For license purchases, we handle only your name, email, and purchase records, as described in the Privacy Policy, which forms part of these terms.

6. Availability

We aim for high availability of the license service, but it is provided without a formal uptime SLA. Because licenses are verified offline, availability of the license service never affects your running CH-UI deployment. Enterprise agreements may include specific SLA and support commitments.

7. Disclaimer of warranty

The software and service are provided "as is" and "as available", without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose, and noninfringement.

8. Limitation of liability

To the maximum extent permitted by law, CH-UI shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, or data. Our total liability for any claim relating to the service is limited to the amount you paid us for it in the 12 months preceding the claim.

9. Termination

You may stop using CH-UI at any time. We may revoke a Pro license for material violations of these terms. Termination does not affect your rights to the open-source core under the Apache License 2.0. On request, we will delete your contact details as described in the Privacy Policy.

10. Changes

We may update these terms. Material changes will be posted here with a new "last updated" date; continued use after changes constitutes acceptance.
