Private By Design

Why Local-Only Chat Tools Matter

Your personal conversations are sensitive. That's why we never transmit your data across external networks.

No chat text, timestamps, or media files are ever transmitted to a server. All computation happens locally in your device's memory.

No account registration, no app installation. Just drop your WhatsApp export file and view metrics in milliseconds.

Transparent and independently auditable code on GitHub. Your private communications stay completely in your control.
