Privacy & Security
Your messages stay yours
WhatsApp Web Toolkit is designed around a single principle: your data never leaves your device.
End-to-end private by design
No accounts. No cloud. No telemetry. The extension augments your WhatsApp Web UI locally — that's it.
No Servers
We don't operate any backend that touches your data.
No Tracking
Zero analytics, zero pixels, zero ad networks.
Local-only
All processing happens inside your browser sandbox.
Password Auth
Locks use industry-standard hashing locally.
Our promises
- We do not collect, transmit, or store your messages.
- We do not request permissions beyond what is required for WhatsApp Web.
- All settings are stored locally in your browser.
- Source code reviewed for safety before each release.
