Lock sensitive WhatsApp chats behind a PIN & blur your sidebar from prying eyes. 100% local, nothing uploaded. PIN-lock your WhatsApp Web chats. Keep sensitive conversations private with a 4-digit PIN — right inside your browser, no app needed. WhatsApp Web does not let you lock individual chats. This extension adds that missing feature directly to WhatsApp Web on Chrome. Select any chat or group, set a PIN, and that conversation stays hidden behind a lock screen until the correct PIN is entered. —————————————————————————— WHAT THIS EXTENSION DOES —————————————————————————— PIN-Lock Any WhatsApp Chat Choose which conversations to protect. Once locked, the message preview in your sidebar stays blurred at all times — even when you hover over it. Clicking the chat shows a PIN entry screen, not the messages. Only the correct 4-digit PIN unlocks it. Master PIN Protection A separate master PIN protects your extension settings. Nobody can change your locked chat list without it. Blur Message Previews Message previews of locked chats stay blurred in the WhatsApp Web sidebar — so even a quick glance at your screen reveals nothing. Works Instantly — No Setup Install, set your PIN, pick the chats to lock. Done. No account, no sign-in, no configuration. —————————————————————————— WHY PEOPLE USE THIS EXTENSION —————————————————————————— ✦ You work in an open office and colleagues can see your screen ✦ You share a laptop with family, flatmates, or a partner ✦ You screen-share in meetings or presentations ✦ You hand your laptop to someone and don't want them opening private chats ✦ You want WhatsApp Web to feel as private as WhatsApp on your phone —————————————————————————— PRIVACY FIRST — ALWAYS —————————————————————————— Everything runs 100% locally inside your browser. ✦ No messages are ever read or uploaded ✦ No contact data is collected ✦ No external servers beyond license verification ✦ PIN values are stored as hashed values only — never plain text ✦ Built with Chrome Manifest V3 — the most secure extension standard —————————————————————————— FREE vs PRO —————————————————————————— Free Plan — Lock up to 2 chats, forever free Pro Plan — Lock unlimited chats, priority support Upgrade to Pro with a one-time payment or a subscription.
