Privacy Policy

1. Overview

This Privacy Policy describes how MarketBoard ("we", "us", "our"), operated by Fernando Vogt, collects, uses, and shares information when you visit and use our website. By using MarketBoard, you agree to the practices described in this policy.

MarketBoard is a real-time financial data display tool intended for informational purposes only. It is not a financial advisory service. All prices and data displayed are provided by third-party sources and should not be used as the sole basis for financial decisions.

2. Information We Collect

We collect minimal information necessary to operate the service:

• Usage data: Standard web server logs may include your IP address, browser type, operating system, referring URL, and pages visited. This data is used for security and analytics purposes only.
• Local preferences: Your display settings (selected assets, font sizes, color theme, currency) are stored locally in your browser using localStorage. This data never leaves your device.
• No account required: MarketBoard does not require registration, login, or any personal information to use.

3. Third-Party Services

MarketBoard retrieves market data from the following third-party providers. When you use MarketBoard, your browser may make requests directly to these services:

• CoinGecko API — cryptocurrency prices. See their privacy policy.
• Yahoo Finance — equity indices, commodities, and FX rates. See Yahoo's privacy policy.
• Google Fonts — typography loaded from Google's CDN. See Google's privacy policy.
• AllOrigins — a CORS proxy used to access Yahoo Finance data. Requests are anonymized.

We do not control the data practices of these third parties and encourage you to review their respective privacy policies.

4. Advertising — Google AdSense

MarketBoard displays advertisements served by Google AdSense. Google, as a third-party vendor, uses cookies to serve ads based on your prior visits to this and other websites.

• You may opt out of personalized advertising by visiting Google's Ads Settings.

We do not control which specific ads are displayed. Ad content is determined entirely by Google based on contextual and/or behavioral signals.

5. Cookies & Local Storage

MarketBoard uses browser localStorage (not cookies) to save your display preferences such as selected assets, theme, and font sizes. This data:

• Is stored entirely on your device
• Is never transmitted to our servers
• Can be cleared at any time via your browser settings

Third-party services (Google AdSense, Google Fonts) may set their own cookies. Please refer to their respective privacy policies for details.
