Serene Guardian - Parental Controls

Protect your children online with age-based content filtering, scheduled browsing times, and comprehensive activity logging.

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) 💎 FREE vs PREMIUM ($2/month) Free: • URL-based site blocking • Age-based filter presets • 2 schedule blocks • Basic activity log • Parent PIN lock Premium: • Everything in Free • Content masking (word scanner + image blur) • Custom blocked domains • Unlimited schedule blocks • Screen time tracking & daily limits • Log export (JSON) • Temporary site unlock • Custom mask word list • PIN attempt history 🛠️ TAMPER-PROOF OPTIONS Parents can prevent uninstallation using Chrome Enterprise Policy, Google Family Link, or supervised profiles.
