CIBRU — INDEPENDENT DIGITAL STUDIODEVELOPED BY KRISHNA MONI BORAH
THE PURPOSE

Useful by nature.
Engineered with intention.

A 100% offline, privacy-first viewer for exported WhatsApp conversations (.zip and .txt). Read full chats in a familiar messaging layout, search through thousands of messages instantly, and play voice notes completely offline.

Every release under the Cibru imprint is developed with uncompromising care for battery consumption, memory footprint, and user autonomy. Keystrokes, personal media, and sensitive tokens remain strictly within on-device sandboxes without external telemetry or background tracking.

PRIVACY AT THE CORE

Zero surveillance.
Respect for the user.

Your imported chats stay on your device: Parsed and stored in Android private app storage.

The app does not upload chat content to developer servers or advertising providers.

Cloud backup and device-transfer backup are disabled for chat databases and extracted media.

Audited against path traversal vulnerabilities for safe archive extraction.
