Terms of Service

Version 1.0 · Effective date: January 1, 2025 · Last updated: June 15, 2025

Introduction: Welcome to LingXi AI (the "Service"). These Terms are an agreement between you and the operator of LingXi AI ("we", "us") governing your use of the Service. By registering or using the Service, you confirm that you have read, understood and agree to these Terms and the Privacy Policy.

1. General

1.1 The Service means the AI chat, writing, coding assistance, image understanding, open API and related features we provide through the website (lingxi-ai.com) and our clients.

1.2 We may update these Terms to reflect legal changes, product evolution or operational needs. Updated Terms are published on this page. Your continued use of the Service after an update constitutes acceptance; if you do not accept the update, please stop using the Service and delete your account.

1.3 If any provision of these Terms is held unenforceable, the remaining provisions remain in full force.

2. Accounts & security

2.1 Register with a valid, accurate email address. You are responsible for all activity under your account.

2.2 Keep your credentials safe. Losses caused by your disclosure or poor safekeeping are your responsibility. Report suspected account compromise to us immediately.

2.3 Do not lend, rent, transfer or sell your account to any third party. We may limit accounts showing abnormal sharing patterns (e.g. heavy concurrent use across many devices).

2.4 You may delete your account anytime in Account Settings; associated data is removed or anonymized, except where retention is required by law.

3. Subscriptions & payments

3.1 The Service offers a Free plan and several paid subscription tiers. Features and prices are shown on the Pricing page.

3.2 Paid subscriptions run monthly or yearly; benefits start as soon as payment succeeds. If prices change, the new price applies from your next billing period — never retroactively.

3.3 We accept Visa, Mastercard, American Express and PayPal. Enterprise customers may pay by ACH or wire transfer with invoicing.

3.4 Upgrades take effect immediately with the difference pro-rated for the remaining days; downgrades apply at the start of the next cycle.

4. Auto-renewal & refunds

4.1 If you enable auto-renewal, we'll notify you in-app before each renewal. You can turn it off anytime in Subscription management; turning it off does not affect the current period.

4.2 First-time paid plans include a 7-day money-back guarantee. Monthly plans keep benefits until the end of the billing period after cancel; yearly plans are refunded pro-rata for remaining days.

4.3 If the Service is terminated due to your serious breach of these Terms, fees for the remaining period are non-refundable.

5. Acceptable use

5.1 You agree not to use the Service for any unlawful or harmful purpose, including but not limited to:

5.2 Depending on severity, we may warn, rate-limit, suspend or terminate accounts that violate these rules, and pursue available legal remedies.

6. Content & intellectual property

6.1 Your input and output: you retain rights to the content you input. For AI-generated output, you may use it as permitted by law during an active paid subscription. You are responsible for the legality of your input and your downstream use of outputs.

6.2 Our rights: the Service's software, interface, trademarks, documentation and underlying models are owned by us or our licensors and may not be copied, reverse-engineered or commercially re-licensed without written permission.

6.3 AI output may contain errors or inaccuracies. Verify important information, and apply human review before material decisions.

7. Changes & termination

7.1 We aim for continuous availability (99.95% target for paid plans) but may suspend or adjust features for maintenance, upgrades or events beyond our control, with advance notice where feasible.

7.2 If a free feature changes for cost or policy reasons, we will try to offer an alternative; material changes to paid features carry 30 days' notice.

8. Disclaimers

8.1 The Service is provided "as is". To the maximum extent permitted by law, we are not liable for force majeure, telecom failures, third-party outages, misuse on your side, or data loss not caused by our fault.

8.2 We are not liable for indirect damages (lost profits, lost goodwill, etc.). Except where mandatory law provides otherwise, our aggregate liability is capped at the fees you actually paid in the 12 months preceding the incident.

9. Governing law & disputes

9.1 These Terms are governed by the laws of the State of California, United States, without regard to conflict-of-law rules.

9.2 Disputes arising from these Terms should first be resolved amicably; failing that, either party may bring the case to the state or federal courts located in Los Angeles County, California.
