Overview

This Privacy Policy describes how ChartNox (the "Service") processes personal data in line with generally accepted international privacy principles and applicable data‑protection laws. By using the Service, you consent to this Policy and to our processing of personal data as described here.

Information We Collect

• Account data: email, name (if you sign up) and authentication tokens.
• Usage data: pages viewed, actions taken, device and browser metadata.
• Content you upload: chart images for AI analysis. Files are processed to produce results and are not kept longer than necessary.
• Payment data: handled by our processors (Stripe, Oxapay, and PayPal); we do not store card numbers.
• Cookies and similar tech: used for session security, preferences, and analytics. You can control cookies in your browser.

We are not responsible for any issues, losses, or disputes arising from the use of third-party payment or other third-party applications; such matters are governed by those providers' terms and policies. This Privacy Policy describes our data practices only and does not create any liability or responsibility on our part beyond what is set forth in our Terms of Service.

Purposes and Legal Basis

• Provide and improve features (analysis, charts, personalization) — performance of contract and legitimate interests.
• Secure the service, prevent abuse, and monitor reliability — legitimate interests and legal obligations.
• Process payments and manage subscriptions — performance of contract.
• Communicate product updates and support — consent or legitimate interests; you may opt out at any time.

Data Retention

Uploaded chart images are used to generate results and then discarded as soon as processing completes or within a short operational window. Account and billing data are retained while your account is active and thereafter only as required by law, accounting, and dispute‑resolution needs. Aggregated analytics may be kept for performance and security.

Sharing

We do not sell personal data. We share data only with service providers that help operate the Service (hosting, analytics, customer support, payment, and AI model providers). These providers are bound by confidentiality, security, and data‑processing agreements.

Your Rights

• Right to access and obtain a copy of personal data we hold about you.
• Right to request correction or deletion of inaccurate or outdated personal data.
• Right to restrict or object to certain processing, including direct marketing.
• Right to data portability, where technically feasible.
• To exercise rights, contact support@chartnox.com; we may ask for information to verify your identity before responding.

Security

We implement organizational and technical measures designed to protect personal data, including access controls, encryption in transit, and auditing where appropriate. No method is 100% secure; report issues to support@chartnox.com.

International Transfers

Data may be processed in your country of residence and in other countries where our providers operate (for example, in the European Union, the United States, or other regions). When data is transferred across borders, we rely on appropriate safeguards—such as contractual protections and vendor assessments—to help protect it.

Children

The Service is not intended for children under 18. If you believe a minor provided personal data, contact us and we will take appropriate steps to remove it.

Changes

We may update this Policy to reflect improvements or legal requirements. We will notify you of material changes and update the effective date above.
