Cookie Policy
Effective Date & Last Updated: August 23, 2026
This Cookie Policy explains how VolumeEdge ("we", "us", or "our") uses cookies and modern browser storage technologies (such as localStorage) when you visit our website and terminal at www.volumedge.app.
1. What Are Cookies and Local Storage?
Cookies are small text data files placed on your browser or device when you navigate a website. LocalStorage is a secure browser-based storage mechanism that allows web applications to store preferences and interface configurations locally on your machine without transmitting them to third-party ad networks on every HTTP request.
2. How We Use Cookies & Storage Technologies
VolumeEdge uses cookies and LocalStorage strictly for essential functionality, session security, and state persistence:
- Essential Authentication Cookies (Supabase Auth): Secure JWT session tokens (e.g.
sb-*-auth-token) that maintain your encrypted login state as you switch between the Chart Terminal, Fundamental Scorecards, and Financial Statements. - Functional Watchlist & Preferences (LocalStorage):
volumeedge_user_watchlist: Preserves your custom-starred stock tickers for instant offline retrieval and guest browsing.- Terminal indicator preferences (active SMA/EMA lengths, RSI, MACD, CVD toggle states, candle width settings).
- Financial statement expansion preferences (collapsible balance sheet, income statement, and cash flow categories).
- Payment Security Cookies (Stripe): Provided by our payment partner Stripe during checkout or customer portal sessions to prevent fraudulent transactions and verify cryptographic payment intents.
