Browser Sentinel is a local-first browser extension that detects and warns about suspicious popup, navigation, overlay, fullscreen, and pointer-lock behavior. This policy explains how the beta handles information.
To provide its detection function, Browser Sentinel processes browser navigation events, website hostnames, page layout characteristics, and whether a page contains a small built-in set of security-scare phrases or certain interface elements. Processing occurs on the user’s device.
When suspicious behavior is observed, the extension may store a local event containing:
- Event timestamp
- Website hostname (not the full URL)
- Numeric risk score and severity
- Generic detection category and reason labels
- A temporary browser tab identifier
Browser Sentinel does not store page text, page HTML, passwords, form values, telephone numbers, full URLs, screenshots, cookies, authentication tokens, or personal communications.
Information is used only to calculate and display local browser-behavior warnings, show recent events, apply user settings, and allow the user to exclude exact trusted hostnames from detection.
Information is stored only in Chrome’s local extension storage on the user’s device. The extension keeps at most 100 detection events and automatically discards older events. Users can clear event history from Browser Sentinel Settings. Uninstalling the extension causes Chrome to remove its extension storage, subject to Chrome’s own behavior and policies.
Browser Sentinel BETA 0.1.0 does not transmit user data to the publisher or third parties. It has no analytics, advertising, telemetry, account system, or remote service. The publisher does not sell user data.
The extension minimizes retained information, limits its history size, packages all executable code with the extension, and does not execute remotely hosted code. Because no system can guarantee absolute security, users should keep Chrome and their operating system updated and use Browser Sentinel as one layer of protection.
Browser Sentinel is not directed to children and does not knowingly collect personal information from children.
If a future version changes these practices, the publisher will update this policy and provide any disclosure or consent required by Chrome Web Store policy before the changed data handling begins.
Browser Sentinel’s use of information received from Chrome APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. Information is used only to provide and improve the extension’s user-facing browser-behavior detection purpose. It is not sold, used for personalized advertising, or transferred to third parties, and humans do not read it.
