What This Extension Does
Break Reminder is a lightweight lifestyle extension designed to help users maintain well-being by sending customizable notifications for hydration, stretching, or other breaks. It operates entirely within the browser without accessing external networks or reading page content, making it suitable for general users seeking productivity aids. The extension utilizes standard Manifest V3 architecture with minimal permissions and no known security vulnerabilities.
Permissions Explained
- notificationsexpected: This permission allows the extension to pop up alerts on your screen to remind you to take breaks or drink water.
Technical: Accesses the chrome.notifications API. This creates a minimal attack surface where an attacker could theoretically spoof notifications, but since the extension has no network access or content script injection, it cannot read sensitive data to craft malicious messages. - storageexpected: This allows the extension to save your reminder settings (like time intervals and message types) so they persist when you restart Chrome.
Technical: Accesses chrome.storage.sync or chrome.storage.local. Data is stored locally in the browser's isolated storage area, not sent to external servers. If compromised, an attacker could read these settings but cannot access passwords or cookies due to same-origin policy isolation.
Your Data
This extension does not send any data to external servers. All your reminder preferences are stored locally within your browser, and no personal information leaves your device.
Technical Details
Code Findings
The extension only does exactly what it says: show notifications and save settings. It doesn't read your web pages or send data anywhere.
Technical: Code behavior analysis confirms the presence of event listeners for notification triggers but no content script injection (None). The absence of network activity means there is no channel for exfiltration of user data.
💡 Well-being extensions typically require only notifications and storage to function without needing invasive permissions like 'activeTab' or 'storageSync'.
The extension relies on Chrome's built-in security rules rather than custom ones, which is safe for simple tools.
Technical: Content Security Policy header is not set (not set). This defaults to a restrictive policy that prevents inline scripts and external resource loading unless explicitly allowed by the manifest. Since no network calls are made, this default restriction provides sufficient protection against XSS or data leakage.
💡 Simple utility extensions often omit custom CSP headers because they do not load third-party resources or execute complex logic that would require explicit whitelisting.
Break Reminder is a secure, low-risk extension that strictly adheres to the principle of least privilege. It poses no threat to user privacy as it lacks network access and does not read web page content. Users can confidently install this tool to improve their daily habits without compromising browser security.
