Product Facts
WaVault
WaVault is a privacy-first WhatsApp CRM Chrome extension that gives users granular control over contact exports from WhatsApp Web. Unlike bulk export tools that dump all contacts into one file, WaVault lets users filter by contact type (unsaved, business, groups), select individual contacts, and export only who they need. It features persistent local memory that remembers contacts even after they leave groups, community churn analytics, and AES-256 encrypted local storage. All processing happens 100% locally in the browser with zero data transmission to external servers.
