Privacy Policy

1. Overview

ChartPilot ("we", "us", or "our") operates the website at https://chartpilot.live and the ChartPilot Chrome Extension. This Privacy Policy explains what data we collect, how we use it, and your rights regarding that data.

By using ChartPilot, you agree to the collection and use of information as described in this policy.

2. Information We Collect

2.1 Account information

When you register, we collect your first name, last name, and email address. Your password is stored as a one-way cryptographic hash — we never store it in plain text.

2.2 Chart screenshots

When you submit a chart for analysis — either through the web app or the Chrome Extension — the screenshot image is sent to our backend and forwarded to OpenAI's API (GPT-4o Vision) for analysis. We do not permanently store your chart images. Screenshots are processed in memory and discarded after the analysis is complete.

2.3 Analysis results

The structured output of each analysis (bias, confidence, support/resistance levels, patterns, etc.) is saved in our database and associated with your account so you can view your history.

2.4 Usage data

We log credit usage, analysis counts, and timestamps to operate the credit system and prevent abuse. We do not track your general browsing history.

2.5 Chrome Extension data

The Chrome Extension captures a screenshot of the currently visible browser tab only when you explicitly click "Analyze current chart". It also reads the active tab's URL and title to detect whether you are on a charting platform. This data is sent directly to our API for analysis and is not stored beyond what is described in Section 2.3. Your extension token is stored locally on your device using chrome.storage.local.

3. How We Use Your Data

• To provide AI-powered chart analysis
• To manage your account and credit balance
• To store your analysis history
• To authenticate your session and Chrome Extension access
• To send transactional emails (e.g. email verification)
• To prevent fraud and abuse

We do not use your data for advertising, profiling, or any purpose unrelated to providing the ChartPilot service.

4. Data Sharing

We do not sell your personal data to third parties.

We share data only with the following service providers, strictly to operate the service:

• OpenAI — chart screenshots are sent for GPT-4o Vision analysis. OpenAI's data handling is governed by their privacy policy.
• Neon (PostgreSQL) — our database provider stores account and analysis data.
• Netlify — our hosting provider processes web requests.

5. Data Retention

We retain your account data for as long as your account is active. Analysis results are retained to power your history view. You may request deletion of your data at any time by contacting us at support@chartpilot.live.

6. Security

We use industry-standard security practices including:

• Passwords hashed with bcrypt
• Extension tokens stored as SHA-256 hashes (raw tokens never stored)
• HTTPS for all data in transit
• Database access restricted to backend services only

7. Your Rights

Depending on your location, you may have the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your account and associated data
• Object to certain processing of your data

To exercise any of these rights, email us at support@chartpilot.live.

8. Cookies

ChartPilot uses browser localStorage and sessionStorage to store your session and analysis data locally. We do not use third-party tracking cookies or advertising cookies.

9. Children's Privacy

ChartPilot is not intended for users under the age of 18. We do not knowingly collect data from minors. If you believe a minor has created an account, please contact us and we will delete it promptly.

10. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes by updating the effective date at the top of this page. Continued use of ChartPilot after changes constitutes acceptance of the updated policy.
