Google PlayAvailable on Android, iOS, and Web browsers instantly without installation.
Why Everyday Conversations Require True Protection
Behind convenient free messaging lies the quiet accumulation of personal chats and metadata on central servers.
Centralized Long-term Data Retention
Years of chats, photos, and files accumulate on central servers, creating serious risks of external exposure and data breaches.
Data Profiling & Targeted Advertising
Private conversations and user behavioral patterns are processed into commercial marketing targets without transparent consent.
Recoverable Data After Deletion
Conventional messengers retain server backups or cache traces when you unsend messages, leaving sensitive content vulnerable to recovery.
Forced Contact Sync & Privacy Leakage
Mandatory phone number registration automatically exposes your profile to colleagues, clients, and unintended acquaintances.
Ieum is engineered on strict Zero-Knowledge principles.
Decryption keys remain solely on your local device. The relay server immediately purges messages from memory upon delivery — no server administrator or third party can ever view or reconstruct your conversations.

Our Mission and Architectural Vision
As digital communication became the default medium of human interaction, private dialogues and personal sovereignty became increasingly hostage to centralized platforms.
Under the guise of 'free' services, personal thoughts are indexed and commercialized. The fear that unpinned or unsent thoughts might linger forever on distant servers undermines the very authenticity of communication.
Ieum was built to return data ownership to where it rightfully belongs: with the user. By combining zero-knowledge E2EE cryptography with a lean, ad-free architecture, we ensure private conversations remain genuinely private.
