Terms of Use

1. Acceptance & Scope

This agreement is entered into between Chaosm ("we") and you (an individual or the entity you represent). Chaosm is a brand of Tianjin Wanjinda Technology & Trade Co., Ltd., which operates this website and acts as the selling entity. By visiting Chaosm websites or purchasing, installing, or using any Chaosm product or service, you acknowledge that you have read, understood, and agree to be bound by this agreement.

If you use a product on behalf of an entity, you represent and warrant that you have authority to bind that entity to this agreement.

2. Definitions

"Product" means Chaosm software products and their documentation; "License" means the usage rights granted under this agreement; "Activation Code" means the credential used to verify and bind a license; "Perpetual License" means a one-time payment model granting permanent use of the licensed version.

3. License Grant

We grant you a non-exclusive, non-transferable, non-sublicensable license to install and use the corresponding product within the feature scope of your purchased edition. Perpetual licenses apply permanently to the version obtained at the time of licensing.

Free editions are used under their published terms, with rights as described on the product page.

4. Usage Restrictions

You may: deploy on your own servers, use for internal operations, and back up configurations and data.

You may not: reverse-engineer for redistribution (except as expressly permitted by law); resell, rent, or share licenses with unauthorized third parties; remove copyright or license notices; resell the product as a hosted service; or circumvent activation and licensing mechanisms.

5. Activation & License Management

Paid products are activated via an activation code bound to your installation instance. Activation requires internet access once; afterwards the product may be used offline permanently.

Keep your activation code safe. You bear the consequences of unauthorized use resulting from your disclosure of the code.

6. Delivery

Paid products are delivered as described on the product page (activation code sent to your payment email). If not received on time, contact us via the channels listed on the website for re-delivery.

7. Pricing, Payment & Taxes

Prices are as published on the product page. Payments are processed by Paddle as Merchant of Record: applicable taxes are calculated, collected, and remitted by Paddle, and invoices are issued by Paddle.

8. Refunds

Refunds are governed by the Refund Policy published on our website: full refund within 14 days of payment if the activation code has not been activated; refunds for defects our support cannot resolve; no refund for activated orders with a normally working product.

Once a refund takes effect, the corresponding activation code is revoked, and continued use constitutes a breach of this agreement.

9. Intellectual Property

All intellectual property rights in the products and their contents (code, documentation, branding) belong to us and are protected by copyright law and international treaties. This agreement does not transfer any intellectual property rights.

Data you generate through use of the products belongs to you.

10. Data & Privacy

Our products are self-hosted by default; your business data stays on your own servers and we do not access or collect it. Personal information is handled per the Privacy Policy published on our website.

11. Documented Use

Use each product as described in its official documentation. Damage or data loss caused by undocumented modifications or operations (including modifying internal files, using unsupported deployment methods, or upgrading without backups) is excluded from support and liability.

12. Support & Updates

Support scope follows the terms of your purchased edition. Free products are supported via community channels.

Perpetual licenses include version updates released within 90 days of delivery; newer versions released afterwards may be purchased separately as upgrades.

13. Disclaimer of Warranties

To the maximum extent permitted by law, products are provided "as is" and "as available". Except as required by law, we make no warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement.

14. Limitation of Liability

To the maximum extent permitted by law, we are not liable for indirect damages (lost profits, business interruption, data loss, etc.); our aggregate liability is capped at the amount you actually paid for the current version.

15. Indemnification

You shall indemnify and hold us harmless from third-party claims arising from your breach of this agreement or unlawful use of the products.

16. Termination

Your license terminates automatically upon breach of this agreement, and you shall cease use and delete the product and its copies. Termination does not affect rights and obligations accrued before termination.

17. Governing Law & Dispute Resolution

This agreement is governed by the laws of the People's Republic of China (excluding conflict-of-law rules). Disputes shall first be resolved through friendly negotiation; failing that, they shall be submitted to the people's court with jurisdiction over us.

This section does not affect any consumer rights you may have under the laws of your country or region that cannot be excluded by agreement.
