NxGen AI Labs ("we", "us", "our") provides the Calanthe AI platform ("Service") at calanthe.ai. This Privacy Policy explains what information we collect, how we use it, and the choices you have regarding your data. By using the Service, you agree to the practices described in this policy.
Our core commitment: We do not use your conversations or personal data to train, fine-tune, or improve AI models — ours or anyone else's.
Account information. When you create an account, we collect your name, email address, and a hashed password, or the profile information provided by your identity provider if you sign in using Google or Microsoft authentication.
Usage and interaction data. We collect metadata about your use of the Service, including session timestamps, features accessed, model selections, and token consumption. This data is used for billing calculations, abuse prevention, and service reliability. We do not log or store the content of your conversations for operational purposes beyond what is necessary to render your chat history.
Payment information. Paid subscriptions are processed by our payment processor. We do not receive or store your full payment card details. We retain subscription status, billing history, and transaction identifiers for account management and legal compliance.
Communications. If you contact us for support or send us feedback, we retain those communications to resolve your request and improve our service.
Technical data. We collect standard technical information such as IP addresses, browser type, and device identifiers for security monitoring, fraud prevention, and service diagnostics. This data is not used for advertising.
We use the information we collect to:
We do not sell, rent, or disclose your personal information to third parties for advertising, marketing, or any commercial purpose unrelated to providing the Service.
We do not train on your data. Your conversation inputs and AI-generated outputs are processed solely to generate responses and deliver the Service to you. Calanthe does not use your conversation content to train, retrain, fine-tune, evaluate, or otherwise improve any AI model.
Conversation storage. Your chat history is stored to provide the history and memory features within the Service. Retention periods are determined by your subscription tier (see Section 8). You may delete individual conversations or your entire history at any time from within the application.
We share your information only in the following limited circumstances:
Service providers. We engage third-party companies to help operate the Service — including payment processing, authentication, sandboxed code execution, and communications. These providers are contractually bound to process your data only as directed by us and in accordance with appropriate confidentiality and security obligations.
Legal requirements. We may disclose information when required by applicable law, court order, or governmental authority, or when we believe in good faith that disclosure is necessary to protect the rights, property, or safety of NxGen AI Labs, our users, or the public.
Business transfers. If NxGen AI Labs is involved in a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction. We will provide notice before your personal data becomes subject to a materially different privacy policy.
With your consent. We may share your information for other purposes with your explicit consent.
We implement technical and organizational security measures designed to protect your personal information against unauthorized access, disclosure, alteration, or destruction. These measures include encryption of data in transit and at rest, access controls, and regular security assessments.
No method of transmission over the internet or electronic storage is 100% secure. While we work hard to protect your information, we cannot guarantee absolute security. If you become aware of a security concern related to your account, please contact us immediately at support@calanthe.ai.
Calanthe uses only essential cookies necessary for the Service to function:
We do not use advertising cookies, cross-site tracking technologies, or third-party analytics that profile your behavior across the web.
The following third-party services are integrated into the Calanthe platform. Each operates under its own privacy policy:
Depending on your jurisdiction, you may have the right to:
To exercise any of these rights, contact us at support@calanthe.ai. We will respond within a reasonable timeframe and in accordance with applicable law. We may need to verify your identity before processing certain requests.
Calanthe is operated from the United States. If you access the Service from outside the United States, your information will be transferred to and processed in the United States. By using the Service, you consent to this transfer. We take appropriate steps to ensure that any such transfers comply with applicable data protection laws.
The Service is not directed to individuals under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that a child under 13 has provided us with personal information, we will take steps to delete such information promptly. If you believe a child under 13 has provided us with their information, please contact us at support@calanthe.ai.
We may update this Privacy Policy from time to time to reflect changes in our practices or applicable law. When we make material changes, we will notify registered users via email or a prominent in-app notice prior to the changes taking effect. The "Last updated" date at the top of this page reflects the date of the most recent revision. Your continued use of the Service after the effective date of any changes constitutes your acceptance of the updated policy.
