Why on Zer0
- Works without phone numbers, servers, or Google services.
- Resilient in low-connectivity or censored environments.
Safe use
- Set a strong app password; enable screen lock.
- Prefer Tor mode; use Bluetooth/Wi-Fi only when required and safe.
- Exchange contacts in person when possible; verify fingerprints.
- Keep attachment sizes small; clear sensitive media from chats.
Limits
- Higher battery usage under Tor; slower message delivery.
- Multi-device usage is limited by design.
