Feature
Pairing with Mutual Approval
Every new pair requires the recipient's approval. The request shows up on their screen — accept or decline. Silent messaging is impossible.
Highlights
- Pair request is shown explicitly
- Channel doesn't open until accepted
- Pair via QR, PIN, or nearby discovery
- Verify the channel with a safety code
Overview
On Zerolog, no one can start a chat with you without your knowledge. When someone wants to talk to you, they send a pair request; that request appears clearly on your screen. Until you accept, no channel opens and no message arrives.
You can pair in several ways: by scanning a QR code in person, by comparing a 6-digit PIN on both devices, by discovering nearby devices over Bluetooth/Wi-Fi, or by searching for a username.
After pairing, both devices show a matching safety code. When you see the same digits, you know the channel was established with no one in the middle.

Internet-free Messaging — Bluetooth & Local Network
When there's no signal, Bluetooth Low Energy and the local network take over; the device next to you stays in reach. Chat and games keep going with no internet. Whichever channel is used, no message is stored on our servers.
On the Internet: End-to-End Encrypted Messaging
On Wi-Fi or mobile data, Zerolog opens an end-to-end encrypted (E2EE) channel in parallel. Keys are generated on your device, never leave for a server. Message content can be decrypted only on the two devices — no one, including us, can read it.
Ephemeral (Self-Destructing) Messages
Each chat gets a lifetime: burn on read, seconds, minutes, hours, or wipe-on-session-end. When the timer runs out, the message is gone from both devices. No undo — because there was no save.
Peer-to-Peer Voice Calls
Zerolog offers encrypted peer-to-peer voice calls. Audio flows directly between the two devices and rings with a native call UI on the lock screen. Call history is not kept.
