Description
Ethical content safety extension (text-only). No spying, no storage of page content. Sentinel is a privacy-first browser extension that helps users stay aware of on-screen content by locally analyzing visible page text and applying user-controlled rules to warn, blur, or block content. All processing happens entirely on your device. Sentinel does not collect personal data, does not track browsing activity, and does not send page content to external servers. Privacy by design Sentinel is built to be transparent and user-controlled. No data collection No analytics or tracking No remote servers No browsing history stored No page content transmitted or saved AI moderation is inactive in this version and makes no network requests Any API keys entered are stored locally only and are not used Key features Local, on-device content awareness Warn, blur, or block modes Guardian Lock (PIN protection) for settings Per-site rules and presets Cooldown timers and friction for bypass actions Privacy-safe debug tools that never copy page text How it works Sentinel scans visible page text only and applies rules you control. It does not monitor keystrokes, form inputs, background activity, or network traffic. Sentinel operates only when enabled. Because detection is rule-based and local, false positives or negatives are possible. Important notes Sentinel is intended for personal awareness and self-regulation, not surveillance. The extension can be disabled or removed by the user. Some iframe or dynamically loaded content may not be detectable. A public privacy policy is available via the link provided in this listing. Sentinel is ideal for users who want a lightweight, transparent, and privacy-respecting way to stay aware of on-screen content without sacrificing control.
