Delete your NANb Chat account and data

Last updated: June 27, 2026

This page explains how to delete your NANb Chat account and what happens to your data when you do. (App package / bundle id: us.nanb.chat.)

Delete your account from inside the app (recommended)

1. Open NANb Chat.
2. Go to Settings.
3. Open Account.
4. Tap Delete account and confirm.

Deletion takes effect immediately.

Can’t access the app?

If you’ve lost access to your devices and still want your account deleted, email contact@nanb.us and include the username you want removed. We will process the deletion for that account.

What gets deleted

• All of your linked devices are revoked and can no longer sign in.
• Your server-side account data is purged, including your device public keys, any push notification token, and any undelivered encrypted messages still queued for you.
• Message history stored locally on your device is removed when you delete the app’s data or uninstall the app. Because NANb Chat is end-to-end encrypted, your conversations live on your devices, not on our servers — we never had the keys to read them.

What is kept, and for how long

• Your username is reserved for 30 days after deletion before it can be reused, to prevent immediate impersonation. After 30 days the username is released.
• We do not retain the content of your messages — by design, we never had access to it.
