About Locktab
LOCKTAB: STOP PEEPING TABS.
Share your laptop without exposing your private tabs. Locktab hides any browser tab behind a blurred overlay or a decoy page — your bank account, your weird DMs, your work-in-progress, whatever it is. Kids, coworkers, roommates, presentation mode: none of them see what's behind the lock.
━━━━━━━━━━━━━━━━━━━━━━━━━
🔒 FOUR INDEPENDENT CHOICES
WHAT YOU LOCK
• A single tab on demand
• An entire domain (auto-lock every visit)
WHEN IT LOCKS
• Manually with Alt+L or one click
• Every time you visit a domain
• When you switch to another tab
• Automatically after 1, 5, or 15 idle minutes
WHAT IT LOOKS LIKE
• Blurred overlay — light, medium, or heavy
• Decoy pages — fake Google, Twitter, YouTube, Instagram, weather, Chrome error page, or new tab page
• Auto-match: show a Twitter-looking decoy on twitter.com, YouTube decoy on youtube.com, etc.
• Or pick one decoy for everything
HOW YOU UNLOCK
• Drag-to-unlock: pull the lock icon into a circle
• Password: SHA-256 hashed, never stored in plaintext
━━━━━━━━━━━━━━━━━━━━━━━━━
🛡️ TAMPER-EVIDENT BY DESIGN
• DevTools keyboard shortcuts blocked while locked (F12, Ctrl+Shift+I, etc.)
• Right-click disabled on the overlay
• MutationObserver re-injects the overlay if someone tries to delete it via DevTools
• Access log of every unlock attempt — successful, failed, or tampered
• Install date tracking — catches uninstall/reinstall attempts via Chrome sync
• 5-attempt password lockout with 60-second cooldown
• Interactive decoy pages that show "Something went wrong" errors when clicked
━━━━━━━━━━━━━━━━━━━━━━━━━
🎭 DECOY MODE
Anyone glancing at your screen sees a broken error page, a fake Google homepage, or an ordinary Twitter feed — not a big "something is hidden here" blur. Triple-click anywhere to reveal the real unlock prompt.
Ships with 7 built-in themes and is designed to be extensible — developers can add custom decoys by dropping a file in the decoys/ folder.
━━━━━━━━━━━━━━━━━━━━━━━━━
🔐 PRIVACY FIRST
• Zero data collected
• Zero outbound network requests
• Zero third-party trackers or analytics
• All settings stored locally in your browser
• Passwords hashed with SHA-256 before storage
• Open and transparent

⚠️ WHAT LOCKTAB IS NOT
Locktab is tamper-evident, not tamper-proof. It's effective against casual snooping and keeps your settings visible if someone tries to bypass it — but it is not a replacement for disk encryption, OS-level user accounts, or dedicated security software.
━━━━━━━━━━━━━━━━━━━━━━━━━
PERFECT FOR
• Parents sharing a laptop with kids
• Coworkers using your machine
• Roommates who borrow your laptop
• Presentation mode (hide tabs before sharing your screen)
• Focus mode (blur a distracting tab you shouldn't be checking)
• Quick privacy for anything you don't want someone glancing at
