Serene Guardian - Parental Controls

About

Serene Guardian gives parents full control over their child's browsing experience — directly from a clean sidebar dashboard inside Chrome.

🛡️ WHAT IT DOES

Serene Guardian blocks inappropriate websites, masks explicit text on pages, enforces screen time limits, and logs all blocked activity — all without slowing down the browser.

✦ SITE BLOCKING
• Blocks sites across 7 categories: Adult Content, Social Media, Gambling, Violence, Gaming, Streaming, and E-Commerce
• Age-based presets automatically adjust filters for ages 5–18
• Add your own custom domains to block or allow
• Blocked sites show a branded page explaining why access was denied

✦ CONTENT MASKING (Premium)
• Scans page text in real-time and masks inappropriate words with black bars
• 3-tier dictionary: Severe (always), Moderate (age ≤ 13), Mild (age ≤ 8)
• Blurs images with suspicious metadata
• Add your own custom words to the mask list
• Works on dynamic content (SPA, infinite scroll)

✦ SCREEN TIME & SCHEDULING
• Set a daily screen time limit (30 min – 8 hours)
• Choose active days (e.g., weekdays only)
• Create time-based restriction blocks (Bedtime, Homework, custom)
• Automatic enforcement — browsing is blocked when limits are hit

✦ ACTIVITY LOG
• Every blocked site is logged with domain, category, timestamp, and full URL
• Search and filter logs by domain or category
• Export logs as JSON for review
• View PIN unlock attempt history (successful and failed)

✦ PARENT PIN SECURITY
• PIN-locked sidebar — child cannot change settings without the parent PIN
• PIN required to unlock blocked sites (temporary 30-minute access, not permanent)
• Brute-force protection: 5 failed attempts triggers a 5-minute lockout
• All PIN attempts are logged with timestamps

✦ FLEXIBLE CONTROLS
• Pause protection for 15 min, 30 min, 1 hour, or 2 hours
• Resume protection early with one tap
• Live countdown timer shows remaining pause time
• Whitelist trusted domains (educational sites, etc.)

🔒 PRIVACY & SECURITY
• All data stays LOCAL in your browser — nothing is sent to our servers
• No tracking, no analytics, no data collection
• PIN stored locally, never transmitted
• Open-source content dictionary — no cloud AI or API calls for content scanning
• Subscription verification uses a secure server-side proxy (API keys never touch the extension)
