Data & account deletion

Luno has no accounts and no servers. There is no Luno-operated database holding your data, so there is nothing for us to delete on your behalf — but there is data on your phone and on your own backend, and this page explains how to remove both.

There is no Luno account

Luno is an open-source app that connects a phone to a backend you run yourself. Installing it creates no account. Nex NeoTech operates no service that Luno talks to, receives no message content, and stores no personal data about you or the people you exchange messages with.

The app communicates with exactly one endpoint: the backend URL you supply during pairing. Where that data goes, how long it is retained, and who can read it are decisions made by whoever operates that backend — which, for a self-hosted deployment, is you.

What the app stores on your device

DataWhere it livesWhy
Outbound and inbound message bodies and phone numbersEncrypted local databaseThe durable queue that survives reboots and network loss
Pairing credentialAndroid hardware-backed keystoreAuthenticates the device to your backend
Device telemetry — SIM, signal, battery, networkIn memory, forwarded to your backendFleet health reporting
Diagnostic logsIn-memory ring buffer, phone numbers maskedThe in-app log viewer

Message bodies and phone numbers are encrypted at rest with a key bound to the device’s keystore. Nothing is written to shared or external storage, and nothing is readable by other apps.

Deleting the data on your device

Tap Unpair node in the app

Open Settings, scroll to Backend, and tap Unpair node — “Clear credential and disconnect”. This performs a full node reset: it deletes the pairing credential, clears the outbox and inbox, drops any cached policy, disconnects from the backend, and cancels background work.

No account exists to delete, and no request to us is required — the button does the whole job on the device itself.

Or uninstall

Uninstalling Luno removes its entire private storage directory, including the encrypted database and the keystore key. Android does this itself; no residue is left behind.

Either route is complete and irreversible. A backend operator can also trigger the same reset remotely by issuing a revoke or wipe command to the device.

Deleting the data on your backend

Anything your backend recorded — message history, device registrations, delivery receipts — lives under your control and is outside the app’s reach. Delete it using whatever tooling that deployment provides.

If you are a user of someone else’s Luno deployment rather than its operator, direct your deletion request to the organisation running it. They are the data controller; the Luno project is not.

Requests about the app itself

The app collects nothing centrally, so there is no request we can action on your data. For anything else — a security report, a privacy question, or a clarification about this page — write to [email protected].
