## FAQ

### Is WhatsApp safe for journalists to use with sources?

WhatsApp uses the Signal protocol for message encryption, but Meta collects extensive metadata including who you contact, when, how often, and your IP address. In January 2025, WhatsApp was used as the vector for Paragon spyware targeting approximately 90 journalists. Signal is the stronger choice for source communication.

### Does WhatsApp collect metadata even with end-to-end encryption?

Yes. WhatsApp encrypts message content but Meta collects contact lists, usage frequency, timing of messages, device information, IP addresses, and location data. This metadata alone can identify sources and map reporter networks.

### Why do some newsrooms still use WhatsApp?

WhatsApp has over 2 billion users globally, making it the default messaging app in many countries. Sources in regions like Latin America, South Asia, and Africa may only have WhatsApp. In those cases, use disappearing messages and move sensitive conversations to Signal when possible.

### Is Signal really free?

Yes. Signal is free, open-source, and funded by the Signal Foundation, a 501(c)(3) nonprofit. There are no ads, no tracking, and no paid tier. The entire codebase is publicly auditable on GitHub.
