+# Security Policy
+
+This document outlines the security procedures and policies for the ThumbCode project.
+
+## Reporting a Vulnerability
+
+If you discover a security vulnerability, please report it to us as soon as possible. We take all security reports seriously and will investigate them promptly.
+
+To report a vulnerability, please email us at `security@thumbcode.com` with the following information:
+
+- A detailed description of the vulnerability, including the steps to reproduce it.
+- The version of the application you are using.
+- Any proof-of-concept code or screenshots that can help us understand the issue.
+
+We will acknowledge your report within 48 hours and will keep you informed of our progress. We ask that you do not disclose the vulnerability publicly until we have had a chance to address it.
+
+## Security Features
+
+The ThumbCode application includes several security features to protect user data and ensure the integrity of the application.
+
+### Credential Storage
+
+- All sensitive credentials, such as API keys and tokens, are stored using `expo-secure-store`, which leverages hardware-backed encryption on both iOS and Android.
+- Credentials are encrypted at rest and are only accessible when the device is unlocked.
+- Biometric authentication (Face ID or fingerprint) is required to access or modify credentials.
+
+### API Communication
+
+- All API communication is protected by TLS encryption.
+- Certificate pinning is implemented to prevent man-in-the-middle attacks. The application will only trust the public keys of the pre-configured API endpoints.
+- All requests to the `mcp_server` are signed with an HMAC-SHA256 signature to prevent tampering and ensure authenticity.
+
+### Input Sanitization
+
+- All user-provided input, including API keys and project information, is sanitized and validated using `zod` before being stored or used.
+- This helps to prevent a range of injection attacks and ensures the integrity of the data.
+
+### Runtime Security
+
+- The application includes runtime security checks to detect if it is running on a rooted or jailbroken device.
+- If a compromised environment is detected, the user will be alerted and the application will exit.
+
+### Web Security
+
+- The web version of the application includes a strict Content Security Policy (CSP) to mitigate cross-site scripting (XSS) and other injection attacks.
+- Other security headers, such as `X-Content-Type-Options`, `X-Frame-Options`, and `Referrer-Policy`, are also in place.
+
+## Secure Development Practices
+
+- All dependencies are regularly scanned for vulnerabilities using `pnpm audit`.
+- The principle of least privilege is followed when requesting permissions.
+- All code is reviewed for security vulnerabilities before being merged into the main branch.
+
+## Security Audits
+
+The application will undergo regular security audits to identify and address any potential vulnerabilities. The results of these audits will be made available to the public.
