Introduction: LingXi AI ("we", "us") takes the privacy of your information seriously. This policy explains how we collect, use, store and protect your information when you use our products and services. Please read it carefully — especially the passages marked in bold — before using our services.
1. Information we collect
We collect only the information necessary to provide the product features you use:
1.1 Information you provide directly
- Account information: the nickname, email address and password (stored hashed) you provide at sign-up.
- Conversation content: the text, files and images you enter in the AI console, used to generate replies.
- Payment information: order records and transaction references created when you subscribe. We do not store your full card number or payment credentials — these are handled by licensed payment processors.
- Support communications: the questions and contact details you provide through our support channels.
1.2 Information collected automatically
- Device & log data: device model, operating system version, browser type, IP address, access times and operational logs, used for service security and troubleshooting.
- Usage data: aggregated statistics such as feature frequency and chat counts, used to improve the product. This data is aggregated and anonymized.
1.3 Information we do not collect
- We do not solicit government ID numbers, financial account numbers, precise location history or other sensitive personal information unrelated to product features.
- We never use your conversation content for advertising.
2. How we use information
We use collected information lawfully, fairly and only where necessary:
- Core service delivery: processing your chat requests and generating replies; managing your account and subscription.
- Security: authentication, anomaly detection, incident investigation and security auditing.
- Product improvement: optimizing model quality and user experience based on aggregated statistics.
- Legal compliance: responding to lawful requests from competent authorities.
About model training: by default, your conversation content is not used to train base models. Pro-plan users and above may opt in to contributing anonymized data for product improvement; this choice can be turned off at any time.
3. Cookies & similar technologies
We use cookies and local storage to keep you signed in, remember your preferences (such as dark mode) and understand product usage.
- Essential cookies: sign-in sessions and security tokens. Removing them breaks core functionality.
- Preference cookies: interface language, theme and similar settings.
- Analytics cookies: anonymized visit statistics.
You can manage or clear cookies in your browser settings, though some features may stop working as a result.
4. Sharing, transfer & disclosure
We do not sell your personal information. We share it only in these situations:
- With your explicit consent;
- Service providers: payment processors, email delivery providers and cloud infrastructure vendors — each receives only the minimum information required, bound by contract to confidentiality and security obligations;
- Legal requirements: compliance with valid legal process from competent authorities;
- Corporate transactions: in a merger, acquisition or bankruptcy, we will require any successor to honor this policy.
5. Storage & cross-border transfer
Your personal information is stored on servers located in the United States. We do not transfer your personal information outside the United States unless the required assessments are completed and your explicit consent is obtained.
6. Data security
We apply industry-standard technical and organizational measures to protect your information:
- TLS encryption in transit; AES-256 encryption at rest;
- Passwords stored with irreversible hashing;
- Least-privilege access control with full audit logging;
- ISO/IEC 27001 certification and regular third-party penetration testing.
If a personal-data security incident ever occurs, we will notify you promptly as required by applicable law and take reasonable remedial measures.
7. Retention periods
We keep personal information only as long as necessary for the purposes described in this policy:
- Chat history: retained for 180 days by default; you can enable "Don't save chat history" or delete records manually at any time;
- Account information: retained while your account is active. After account deletion we remove or anonymize your personal information, except where retention is required by law;
- Transaction records: retained as required by accounting and tax regulations.
8. Your rights
Depending on where you live, you have the following rights over your personal information (residents of California have additional rights under the CCPA/CPRA):
- Access & correction: view and edit your profile in Account Settings;
- Deletion: delete individual conversations or your entire chat history;
- Portability: request an export of your account and chat data in a machine-readable format;
- Withdraw consent: switch off related toggles or delete your account;
- Account deletion: self-service under Account Settings → Delete account, completed within 15 business days.
To exercise these rights, contact bigtopcow@gmail.com. We will respond within 15 business days.
9. Children's privacy
Our services are intended for adults. Children under 13 may not use the service without verified parental consent. If we learn that we have collected personal information from a child under 13 without proper consent, we will delete that information promptly. If you believe a child has provided us information, please contact us.
10. Changes to this policy
We may update this policy from time to time. Material changes (such as expanded collection or new purposes) will be announced in advance via in-app notices, banners or email. If you continue using the service after a change takes effect, the updated policy applies to you.
