+# Security Policy
+
+## Overview
+
+This repository contains MicroPython / CircuitPython code designed primarily for microcontrollers such as the Raspberry Pi Pico and similar embedded devices.
+
+As this project is intended for educational, experimental, and embedded development purposes, the security model differs from that of web applications or cloud-hosted systems. However, responsible disclosure of vulnerabilities is still important.
+
+---
+
+## Supported Versions
+
+Security updates are applied to the latest version of the main branch.
+
+| Version | Supported |
+|---------|-----------|
+| Latest (main branch) | ✅ |
+| Older releases | ❌ |
+
+Users are encouraged to run the most recent version of the code.
+
+---
+
+## Scope of Security Concerns
+
+Relevant security concerns may include:
+
+- Hardcoded credentials or secrets
+- Unsafe handling of Wi-Fi or network connections
+- Insecure data transmission
+- Buffer overflows or unsafe memory usage
+- Exposed debugging interfaces in production deployments
+- Unsafe firmware configuration guidance
+
+Physical access vulnerabilities (e.g., direct USB flashing or hardware probing) are generally considered out of scope unless caused by insecure configuration within this repository.
+
+---
+
+## Reporting a Vulnerability
+
+If you discover a potential security issue, please report it responsibly.
+
+**Please do not disclose security vulnerabilities via public GitHub issues.**
+
+Instead, contact:
+
+📧 [your-email@example.com]
+
+Please include:
+
+- A clear description of the issue
+- Steps to reproduce (if applicable)
+- Affected files or components
+- Potential impact
+
+You can expect:
+
+- Acknowledgement within a reasonable timeframe
+- Investigation of the issue
+- A fix or mitigation where appropriate
+
+---
+
+## Secure Usage Guidelines
+
+When using code from this repository:
+
+- Do not commit Wi-Fi passwords or API keys to version control
+- Store secrets in a separate configuration file excluded via `.gitignore`
+- Avoid exposing devices directly to the public internet without proper safeguards
+- Use secure network protocols where possible
+- Regularly update MicroPython / CircuitPython firmware
