This Cookie Policy explains how Signal MCAT uses cookies and similar technologies when you use our web application. For general privacy practices, please see our Privacy Policy.

1. What Are Cookies?

Cookies are small text files placed on your device by a website when you visit it. They allow the site to remember information about your visit, such as your login status.

2. Cookies We Use

Signal MCAT uses a minimal set of cookies, limited to what is strictly necessary to operate the Service:

Cookie Name	Type	Purpose	Duration	Essential?
session	HTTP Cookie (Signed)	Maintains your authenticated login session using HMAC-SHA256 signing. Expires after 30 days of inactivity.	30 days (sliding)	Yes — required to use the Service

3. Local Storage (UI State)

Signal MCAT uses your browser's localStorage (not a cookie) to preserve lightweight UI state between page loads, such as your last selected tab or review session position. This data:

• Never leaves your device
• Is not transmitted to our servers
• Contains no personally identifiable information
• Can be cleared at any time by clearing your browser's site data for signalmcat.com

4. Third-Party Cookies

Signal MCAT does not set third-party advertising or tracking cookies. However, the following third-party services may set their own cookies or use similar technologies as part of their integration:

Provider	Purpose	More Information
Stripe	Payment processing. Stripe may set cookies to detect fraud and maintain payment session state when you visit our checkout flow.	stripe.com/cookie-settings
Google Fonts	Typography delivery. Google may log IP address when fonts are loaded from their CDN. No persistent tracking cookies are set for our usage.	policies.google.com/privacy

5. Cookie Management

Because Signal uses only one essential session cookie (plus optional third-party integration cookies), you cannot opt out of the session cookie and continue to use the Service in a logged-in state.

You can manage or delete cookies at any time through your browser settings:

• Chrome: Settings → Privacy and security → Cookies and other site data
• Firefox: Preferences → Privacy & Security → Cookies and Site Data
• Safari: Preferences → Privacy → Manage Website Data
• Edge: Settings → Privacy, search, and services → Cookies

Deleting your session cookie will log you out of the Service.

6. Changes to This Cookie Policy

We may update this Cookie Policy as the Service evolves. Material changes will be communicated as described in our Privacy Policy.
