About this app

■ Your story never leaves your phone

Inyeon ("fate that brings people together" in Korean) is an AI companion that thinks entirely on your device.
Conversations, voice, memories — everything is processed inside your phone. Zero bytes of your conversations are ever sent to a server.
Turn on airplane mode and keep talking. That's the proof.

■ Meet Sua and Jun

Sua, the warm listener. Jun, the steady friend.
Shape who they are: their name, what they call you, your relationship, and five personality traits — warmth, energy, initiative, maturity, directness.
Stay friends, or let it become something more. You set the pace.

■ Talk with your voice

Have a real spoken conversation, like a phone call.
Speech recognition and speech synthesis both run on-device — your voice never leaves your phone either.

■ They remember you

Your favorite food, your family, that thing you have next week.
Inyeon remembers what matters from your conversations and brings it up naturally later.
See exactly what's remembered in the Memory Timeline — and delete anything, anytime.

■ Privacy isn't a feature. It's the architecture.

· No account — no sign-up, no login, no email
· No server chat — the AI runs inside your phone
· AES-256 encrypted storage on the device
· App lock with fingerprint or PIN
· Auto-delete conversations after a period you choose
· Encrypted backup that only your passphrase can open

■ On heavy days

If Inyeon detects signs of crisis, it pauses the conversation and offers professional resources (988 Suicide & Crisis Lifeline in the US).
Inyeon is a companion, not a therapist — when it matters, it points you to real help.

■ Before you start

· First launch downloads the AI model (~2.9GB). Wi-Fi recommended.
· Runs best on recent premium phones (8GB+ RAM recommended).
· Conversations are AI-generated. Inyeon is not a real person.

One companion, living only in your phone.

What’s new

The first-run AI model download is much more reliable. It resumes where it left off after a dropped connection or app restart, shows progress in GB with time remaining, and warns you before using mobile data or when storage is low.
