Terms of Service

Last updated: 27 September 2026

1. What LingXi Engine Is

LingXi Engine is an open-source (MIT licensed) multimodal AI agent. It runs on your own machine or your own server, accepts text, images and documents as input, calls tools, maintains long-term memory, and can be reached through a web UI or messaging channels.

The software is provided "as is", without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement.

2. No Paid Services

LingXi Engine itself is free and open source. We do not operate any marketplace, escrow, brokerage, payment, or settlement service, and we do not charge any platform fee.

You may choose to connect a third-party model provider. Any fees charged by that provider are billed by them, under their own terms, and are not governed by these terms. If you run a local model, no third-party fee is incurred at all.

3. Your Data and Your Machine

• The engine is designed to run locally. When self-hosted, your files, prompts and outputs remain under your control.
• When you connect a remote model API, the data you send is handled by that provider under their own privacy policy. Review it before sending sensitive material.
• You are solely responsible for the content you send to the engine and for the actions it takes with your tools, including any command execution you permit.
• Configure filesystem, shell and network permissions narrowly. The agent acts with the privileges you grant it.

4. Acceptable Use

• Do not use the engine for unlawful content, spam, harassment, or any activity that violates applicable law.
• Do not attempt to circumvent access controls or use the engine to attack systems you are not authorised to test.
• Output generated by AI models may be inaccurate. Verify anything important before relying on it.

5. Accounts

• Local AI chat requires no registration at all.
• If an account is created, you must be at least 18 years old, or the age of majority in your jurisdiction.
• You are responsible for the confidentiality of your credentials and for all activity under your account.

6. Suspension and Termination

The operator may suspend or terminate access to hosted components used in abuse, abuse of the service, or illegal activity. Self-hosted installations remain entirely under your own control.

7. Intellectual Property

The LingXi Engine source code is open source under the MIT License. Content you create, and documents you supply, remain yours. You grant the project a non-exclusive licence to display your content only to the extent needed to operate the software for you.

8. Third-Party Models and Content

Content produced with the assistance of third-party models may be subject to those providers' terms. You are solely responsible for reviewing such output before use. The project does not warrant the accuracy, safety, or legality of model-generated output.

9. Limitation of Liability

To the maximum extent permitted by law, the operators and contributors are not liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, arising from your use of the software.

10. Changes

We may update these terms as the project evolves. Material changes will be reflected in the "last updated" date above. Continued use after a change constitutes acceptance.

11. Contact

Questions about these terms can be raised through the project's GitHub Discussions or issue tracker.
