Lock sensitive WhatsApp Web chats behind a 4-digit PIN and blur your sidebar from shoulder-surfers. Everything stays on your device — nothing is ever uploaded.
Six layers of calm for everyone who opens WhatsApp Web at the office, in class, or on a shared screen.
Pick any chat and it hides behind a beautiful lock screen. A 4-digit PIN is the only way in — even mid-conversation.
Names, messages, avatars, timestamps and unread badges blur automatically. Hover to peek — only when you want.
3 wrong PIN attempts trigger a cooldown lockout. Nosy fingers get a timer, not your messages.
Even the extension's own settings hide behind a Master PIN. Nobody can quietly unlock your chats from the popup.
Switch tabs, minimize, or navigate away — every locked chat snaps shut automatically. No "oops, left it open".
PINs are salted & hashed with PBKDF2 (100k rounds) and stored only in your browser. No servers. No accounts. No tracking.
Real screenshots. This is exactly what you'll see.
Open the popup, hit “Pick contacts to lock” and tick anyone — partners, group chats, your boss. Two clicks and they're selected.
One dashboard controls everything: your chat PIN, your locked list, and your plan. It proudly says “100% Local · No data collected” because that's the whole point.
Open a locked chat and the whole conversation goes dark behind a sleek PIN card. Wrong PIN? Shake, cooldown, denied. Right PIN? Smooth unlock, just for you.
Dark, glassy lock screens layered over WhatsApp Web — designed to be invisible until someone snoops.

Never. The extension only adds a visual lock layer on top of WhatsApp Web. There are no servers, no analytics and no message access — everything (settings, PIN hashes) lives in your browser's local storage.
After 3 wrong attempts the lock screen freezes with a cooldown timer. The popup's Master PIN gets 5 attempts before a 60-second lockout. PINs are never stored in plain text — only salted PBKDF2 hashes.
Yes — lock up to 2 chats and use the full sidebar blur forever, no card required. Upgrade only if you want unlimited locked chats.
