Frequently Asked Questions
Clinical technical answers regarding the UNDERWORLD zero-trust architecture, metadata minimization, and secure routing protocols. Review our strict defaults before requesting access.
Why Tor-only?
To prevent network observers from mapping your communication metadata. All traffic fails closed if a secure Tor circuit cannot be established.
Is there a convenience mode?
No. There are no standard fallbacks or plaintext relays. The system operates strictly in high-security mode to eliminate accidental exposure.
What is UNDERWORLD?
Does it upload contacts?
Does it support backups?
UNDERWORLD is a restricted-security Android messenger designed for high-risk communication. It enforces zero-trust architecture, zero cloud storage, and metadata minimization.
No. Your address book stays entirely on your device. We do not collect, process, or store your social graph.
No. Cloud backups represent a critical metadata and content exposure risk. If you lose your device, your messages are permanently deleted.
