Privacy Policy

Last updated: April 2026

1. What We Collect

When you create an account, we collect your email address and display name. When you import trade data, we store your positions, trades, stock holdings, dividends, and related analytics. We also collect stock price data from third-party APIs (Finnhub) to display current market values.

2. How We Use Your Data

Your data is used solely to provide the Options Dealer service — displaying your portfolio, calculating analytics, and tracking your trading performance. We do not use your data for advertising, profiling, or any purpose other than operating the Service.

3. Data Storage and Security

Your data is stored in Supabase (PostgreSQL) with Row Level Security (RLS) enforced at the database level. This means your data is cryptographically isolated — no other user can access your records, and our application code cannot bypass this protection. All data is transmitted over HTTPS with TLS encryption.

4. Data Isolation

Every database table containing user data has Row Level Security policies that restrict access to the authenticated user only. This is enforced by PostgreSQL itself, not application code. Even in the event of an application vulnerability, your data remains isolated.

5. Third-Party Services

We use the following third-party services:

  • Supabase — Database and authentication
  • Vercel — Application hosting
  • Finnhub — Stock price data (no personal data is sent to Finnhub)
  • Google OAuth — Optional sign-in method (we receive your name and email only)

6. Data Retention and Deletion

You can export all your data at any time from the Settings page. You can delete all your data at any time — this permanently removes all your positions, trades, holdings, and analytics. Account deletion removes your profile and all associated data.

7. Cookies

We use cookies only for authentication session management. We do not use tracking cookies, advertising cookies, or analytics cookies. Your theme preference (dark/light) is stored in localStorage, not cookies.

8. Your Rights

You have the right to access, export, and delete your data at any time. You can do this directly from the Settings page without contacting us.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes via email or in-app notification.
