 ### ℹ️ About Radio
 **Radio is an application with a minimalist approach to listening to radio over the Internet.** <br>
 **Radio only offers a very basic search option, and it imports audio streaming links when you tap them in a web browser.** <br>
-**Radio now also supports Android TV (Beta).** <br>
+**Radio now also supports Android TV (Beta) and Cast to Devices (Beta) with the Version 14.5 and above.** <br>
 **Pull request are welcome at any time.**<br>
 
 **Radio is free software. It is released under the [GPLv3 open source license](https://opensource.org/licenses/GPL-3.0).**

+# Security Policy
+
+## Reporting a Vulnerability
+
+We take the security of Radio seriously. If you believe you have found a security vulnerability, please report it via **GitHub Issues** before disclosing it publicly.
+
+**Create a new security issue**: [GitHub Issues — Security](https://github.com/michatec/Radio/issues/new?labels=security). We will respond within 48 hours acknowledging your report and work with you to understand and address the issue.
+
+Include in your report:
+- Description of the vulnerability
+- Steps to reproduce
+- Affected versions (if known)
+- Potential impact
+- Any suggested fixes (optional)
+
+We appreciate responsible disclosure and will credit researchers who report valid security issues (unless you prefer to remain anonymous).
+
+## Supported Versions
+
+| Version | Supported          |
+| ------- | ------------------ |
+| 14.5    | :white_check_mark: |
+| < 14.5  | :x:                |
+
+Only the latest stable release receives security updates. Users on older versions are encouraged to update.
+
+## Security Considerations
+
+### Network Security
+Radio streams audio over the internet and connects to the [radio-browser.info](https://www.radio-browser.info/) API for station search. The app allows cleartext HTTP traffic for radio stream compatibility (required for many legacy radio stations).
+
+### Data Collection
+- **Station data** (names, images, stream URLs) is fetched from radio-browser.info's public API
+- **Station lists** are stored locally on the device only
+- **No personal data** is collected or transmitted to michatec servers
+- **Usage data** is not collected
+
+### Permissions
+Radio requests only the permissions necessary for core functionality:
+- `INTERNET` — stream radio and fetch station metadata
+- `ACCESS_NETWORK_STATE` — detect connectivity changes
+- `FOREGROUND_SERVICE_MEDIA_PLAYBACK` — maintain playback when app is backgrounded
+- `WAKE_LOCK` — prevent device from sleeping during playback
+
+### Third-Party Dependencies
+Radio uses several third-party libraries. Security issues in dependencies are monitored via Renovate bot for updates. Key dependencies include:
+- AndroidX Media3 / ExoPlayer (media playback)
+- Google Cast SDK (Chromecast support)
+- Volley (HTTP requests)
+
+### File Handling
+The app can import M3U/PLS playlist files from external sources. Files are processed locally and stream URLs are validated before playback. Station images are downloaded from radio-browser.info and cached locally.
+
+## Security Update Process
+Security patches are delivered via normal app update channels (GitHub Releases, automated update notifications). Critical vulnerabilities may trigger an out-of-band security update.
+
