Feature
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.
Highlights
- Per-chat lifetime (TTL)
- Burn-on-read or wipe on session end
- Full wipe on app close
- Content never on disk — RAM only
Overview
At the heart of Zerolog is a single idea: a conversation that isn't stored can't be abused. For each chat you set a lifetime (TTL) — burn the moment it's read, last a few seconds, minutes, hours, or vanish when the app closes.
Messages are never written to disk or a database; they live only in the device's memory (RAM). When the timer fires they drop from both your device and the other side's. With no copy to recover, there is no "undo" either.
This works the same way over close range and over the internet. Leaving no trace isn't a setting — it's the product's default way of working.

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.
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.
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.
