Instagram Chat Lock & Hide – Lock or Hide Specific DMs

Some conversations aren't for everyone. This extension lets you hide chats from your Instagram inbox and lock others behind a PIN, so a glance over your shoulder shows nothing you didn't choose to show. Everything happens inside your own browser. No login, no password, no account, and nothing is ever uploaded. WHAT IT DOES • Hide Contacts: pick a conversation and it quietly disappears from your inbox view. Nothing is deleted, and you can bring it back anytime. • Lock Chats: protected conversations ask for a 4 digit PIN before they open, even if your laptop is already unlocked. • Master PIN: the extension panel itself sits behind its own PIN, so nobody can change your settings. • Kill Switch: turn the whole extension off in one click when you don't need it. HOW IT WORKS 1. Set a 4 digit master PIN for the panel 2. Choose which chats to hide, and which to lock 3. Your inbox looks normal again. Hidden chats are gone from view, locked ones need a PIN PRIVACY FIRST • All PINs are stored as SHA-256 cryptographic hashes, never as plain text • Your message content is never read, copied, or transmitted • No analytics, no tracking, no advertising identifiers • The only network request is a license check when you activate or verify a Pro key • We never ask for your Instagram password FREE TO START The free tier includes 1 hidden contact and 1 locked chat, so you can try both features properly before paying anything. GO PRO FOR UNLIMITED Upgrade to Pro for unlimited hidden contacts and unlimited locked chats. Flexible plans: a 1 Day Trial Pass, 1 Month, 6 Months, 1 Year, or one time Lifetime Access. Your license is locked to your device and no account is needed. IMPORTANT TO UNDERSTAND This extension changes how your inbox looks on this browser only. It does not delete messages, does not block anyone, and does not change anything on Instagram's servers. Someone opening Instagram on a different device or browser will see the normal inbox.
