Privacy Policy

Last updated: September 2026

The Zero-Knowledge Pledge: We do not track, collect, transmit, store, or sell any information you enter into the portfolio calculator. All data processing occurs 100% locally in your web browser.

1. Local Processing & Storage

When you enter ticker symbols, cash balances, or target percentages into our tool, this data is processed exclusively within your device's browser execution environment. For your convenience, your current input state is saved locally to your device's browser localStorage so your session persists across page refreshes. You can clear this data at any time by clicking the "Clear All" button or purging your browser cache.

2. Log Files & Anonymous Analytics

Like all standard web servers and content delivery networks (Cloudflare), our hosting infrastructure may collect standard, non-personally identifiable diagnostic server logs (such as IP address, browser user-agent, operating system, referring URL, and timestamp). These logs are utilized solely to ensure server availability, mitigate DDoS attacks, and optimize content delivery speeds.

3. Cookies & Advertising

We do not use tracking cookies to identify individual users. We may display privacy-compliant, contextual advertisements to offset server and domain operational costs. Third-party vendors, including Google, use cookies to serve ads based on prior visits to this or other websites. Users may opt out of personalized advertising by visiting Google's Ads Settings.

4. Contact Information

If you have any questions regarding our privacy practices or wish to inquire about our zero-knowledge architecture, please contact us at [email protected].
