Frequently Asked Questions
Use guidelines for Ieum, the serverless P2P messenger.
No, they are never stored anywhere.
Ieum is fundamentally different from traditional centralized messengers. Our servers only provide an encrypted "routing handshake" for a fraction of a second to approve the connection based on your IP. Once the connection is established, your messages travel directly (P2P) from your smartphone to your friend's smartphone. The server logs instantly vanish.

Not even a single byte is sent externally.
The 'AI Document Vault' utilizes the latest Local RAG technology. When you upload a document, your smartphone natively reads and chunks the text into a Vector DB that strictly resides on your device's internal memory. Even when you ask questions, the phone processes the answers entirely offline without sending your prompts to external APIs. You can safely let your AI assistant read highly confidential company documents or private diaries.

Yes, Ieum features Auto Device Optimization tech.
When you first run the app, it automatically measures your device's available RAM and decides whether to load a lightweight model (e2b) or a high-performance model (e4b). Therefore, you can comfortably enjoy on-device AI without worrying about excessive battery drain or overheating, even on non-flagship devices.

Calls are conducted entirely through P2P direct connections.
We only use the push notification server for a split second to send the encrypted "wake up" signal. The moment you accept the call, both devices completely bypass the servers and establish a 1:1 direct WebRTC tunnel, much like walkie-talkies. Because there is no intermediary "bridge," it is physically impossible for anyone to eavesdrop or record the call on a server.

It's your only ID card, protecting you from handing over your phone number or email.
Instead of forcing you to verify a phone number—which compromises anonymity—Ieum issues an anonymous ID by making your device solve a light cryptographic puzzle (PoW). The provided 12-word secret phrase (Mnemonic) is your only master key.
If you lose these words and change your device, it is permanently impossible to recover your account. Neither the Ieum development team nor anyone else can recreate it. You must write it down and store it in a safe place.

While typing in the chat, long-press and swipe left on the send button to activate the 'Time Bomb' icon. Whether set for 10 seconds or 10 minutes, the message will vanish like smoke from both your and the recipient's phone memory.
Even without timers, you have complete control: long-press any previously sent message and choose [Delete for Everyone]. This instantly and permanently deletes the content from the recipient's screen, no matter how much time has passed.

They are shredded from the relay cloud the exact moment the recipient views them.
When sending media, the Ieum app temporarily stores the encrypted file on an S3 relay bucket. The instant the recipient's device receives and successfully downloads the file, it is permanently and irreversibly deleted from our servers. There is 0% risk of your shared files lingering in central databases.

No. Distance calculations are one-off triggers only when YOU press the button.
Ieum respects your privacy. The app only scans for nearby users during the brief moments you actively enable the radar in the feature screen. We never track your GPS in the background, nor do we log your daily location routes on central servers. Please use it with peace of mind.
