Frequently Asked Questions
Comprehensive guidance on Ieum's security architecture and features.
Account & Security
Why is the 12-word master key so critical?
Ieum does not store user passwords or personal profiles on central servers. The 12-word master key generated on your device is the sole mathematical credential to recover your account and cryptographic keys. Never disclose it to anyone.
Can I really use Ieum without a phone number or email?
Yes. Ieum requires zero personal identifiers. When launched, an asymmetric cryptographic keypair is generated directly on your local device, eliminating risks of phone leaks or forced contact harvesting.
Can my chats be exposed if a third party requests server data?
No. Ieum operates on a strict Zero-Knowledge architecture. All messages are encrypted with X25519 E2EE and wiped from server memory immediately upon delivery. No past chat logs or private keys are ever stored on central servers, meaning zero chat data exists to be disclosed.
Messages & Privacy
What happens when I delete a message? Can it be recovered?
When you delete a message in Ieum, a clean 'This message was deleted' placeholder remains to preserve conversation flow, but the plaintext message content, attachments, and encryption keys are permanently destroyed across devices and servers. It is impossible to recover the message through backups or digital forensics.
How does an anonymous Whisper room work?
Whisper is an end-to-end encrypted room where participants interact using temporary aliases rather than personal accounts. Once the preset duration elapses, the room and all contained message data safely and irreversibly expire.
Platforms & Compatibility
Does the web browser version maintain the same level of security?
Yes. Connecting to app.ieum.life provides the exact same end-to-end cryptographic protection as native apps, running directly in modern browsers without needing software installations.
