Cookie Policy

What Are Cookies & Local Storage?

Cookies are small text files stored on your computer, smartphone, or tablet when you visit a website. In addition to cookies, modern web platforms use Browser LocalStorage and SessionStorage to temporary keep data in your browser memory.

These technologies allow websites to remember your settings, optimize page loading speeds, and deliver smooth mathematical interaction without sending data back to servers.

How Stockmetric.io Uses Cookies & Browser Storage

Our commitment to user privacy means we keep cookie usage strictly functional and non-invasive. We utilize storage for the following specific purposes:

• Session State Maintenance: Temporary browser memory keeps active calculation inputs intact while you switch between calculator tabs.
• Security & DDoS Protection: Technical security tokens protect our platform infrastructure against automated malicious spam and bot attacks.
• UI Preferences: Preserving custom interface preferences (such as dark/light theme toggles or currency formatting choices).

Types of Cookies & Technologies We Employ

Below is a breakdown of the web storage mechanisms used on our platform:

• Strictly Necessary Cookies: Essential for standard website navigation, page load balancing, and network security. These cannot be disabled as the site cannot function properly without them.
• HTML5 SessionStorage (Client-Side): Used locally to hold your math inputs during an active browsing session. This memory is automatically purged when you close the browser tab.
• Anonymized Performance Telemetry: Anonymized server health metrics used solely to monitor website uptime, bandwidth, and page load response speeds.

What We DO NOT Do With Cookies

To preserve total financial anonymity, Stockmetric.io strictly enforces the following privacy rules:

• We DO NOT store your portfolio numbers, stock selections, or personal financial inputs in cookies.
• We DO NOT sell, rent, or trade your browser cookies to financial brokers, market research firms, or ad networks.
• We DO NOT use cross-site retargeting cookies to follow your activity across external commercial websites.

Third-Party Cookies Disclaimer

Some pages on Stockmetric.io may contain embedded reference content or external links (such as stock exchange guidelines or official data sources). Third-party sites have independent privacy and cookie policies. We encourage you to consult the cookie policies of those external domains when visiting them.

How to Control and Delete Cookies

You have the full right to accept, refuse, or clear cookies at any time through your web browser settings. Below are quick guides for popular browsers:

• Google Chrome: Settings → Privacy and security → Cookies and other site data.
• Mozilla Firefox: Options → Privacy & Security → Cookies and Site Data.
• Apple Safari: Preferences → Privacy → Block all cookies.
• Microsoft Edge: Settings → Site permissions → Cookies and site data.

Impact of Disabling Cookies

Because Stockmetric.io's calculation algorithms run locally inside your browser via client-side JavaScript, disabling cookies will not break our financial calculators. You can continue calculating DCF values, position sizes, and mortgage schedules even with cookies completely turned off.

Updates to This Cookie Policy

We may update our Cookie Policy periodically to reflect technological improvements or legal updates. Any changes will be posted on this page with an updated "Last Updated" revisions date.
