Qingtan · Your private space to talk
Encrypted one-to-one messaging designed to protect every private conversation.
Worried that someone may scroll through your private chats? Sent something personal to a work group by mistake? Had a partner check your phone? Lent your phone to someone and risked exposing private information? Qingtan is designed to solve these everyday privacy concerns. Rename the app and change its icon to make it look like an ordinary utility. Its true purpose stays discreet, keeping curious eyes away from private conversations and helping prevent embarrassing messages from being sent to the wrong chat. Password verification is required whenever you switch back to the app, wake the screen or unlock the phone. If someone asks for your password, enter the decoy password to open a harmless utility interface—such as a ledger, cycle tracker or private album—while your real conversations remain completely hidden. Privacy-first notifications still alert you to new messages while hiding message content and the true unread count.
