Nexo Privacy Policy

Applies to Nexo for Mac, Nexo for Android and Nexo for iPhone (together, “Nexo”).
Effective date: 2 October 2026  ·  Last updated: 2 October 2026

1. The short version

Nexo does not collect your data. It has no accounts, no servers of ours, no analytics, no advertising and no tracking.

What you copy and the files you send go directly between your own devices (Mac, iPhone and Android phone), over your local Wi-Fi network, encrypted. We never see them.

2. Who we are

Nexo is published by e404 Technology (“we”, “us”). You can reach us at [email protected].

3. Data we collect

None. Nexo does not send any personal data, usage data, diagnostics, crash reports, device identifiers or advertising identifiers to us or to anyone else. We do not sell or share personal data, because we do not have any.

The apps do not contain third-party analytics, advertising, attribution or crash-reporting software.

4. How Nexo handles your data

Nexo exists to move things between two devices that you own. When you use it:

All of this happens on your own network. Nexo does not use the internet to move your clipboard or files, and nothing passes through our servers, because we do not run any.

5. What is stored on your devices

ItemWhereWhyRemoved when
Device identity (a cryptographic key and certificate)Mac: Keychain. Android: Android Keystore (the key cannot be exported)So your devices can recognise each otherYou uninstall the app
List of paired devices (name, ID, last known network address)On each device, inside the app’s private storageSo devices reconnect automaticallyYou remove the device in the app, or uninstall
Settings (for example whether clipboard sharing is on)On each deviceTo remember your choicesYou uninstall the app
Files you acceptDownloads/Nexo folder on the receiving deviceThat is the point of the transferYou delete them
Files copied on the Mac for pasting on the phoneAndroid: the app’s private cacheSo you can paste or share themReplaced by the next copy, or when you clear the app’s cache
Temporary copies made while sending from the phone, and partly received filesAndroid: the app’s private cache. Mac: the Downloads/Nexo folder (hidden until complete)So a transfer can finish or resume after a dropped connectionThe transfer ends, is cancelled, or fails
Short-lived inbox for Finder “Share → Nexo”Mac: a shared app folderHands chosen files from the Finder extension to the appThe transfer starts; leftovers are cleared after 24 hours

None of this is sent to us. On Android, Nexo writes technical events to the phone’s ordinary system log (for example the name and local network address of your paired Mac when connecting, or an error message). It never writes your clipboard contents or file contents there, and the log stays on your phone.

6. Permissions and why

Nexo for Android

PermissionWhat it is used for
Network access (Internet), network state, Wi-Fi stateTo open connections to your Mac on your local network and notice when the network changes. Nexo does not send your data to internet servers.
Multicast stateTo discover your Mac on the network.
NotificationsTo ask you to accept incoming files, show progress, and show that Nexo is connected.
Foreground service (connected device)To stay connected to your paired Mac in the background. A persistent notification shows while it runs.
Receive boot completedTo restart the connection after the phone restarts, if a Mac is paired.

Nexo does not request access to your contacts, location, camera, microphone, photos, storage, phone, SMS or accounts. Saving to the Downloads folder uses Android’s built-in file store and needs no storage permission. Scanning the pairing code uses Google’s code scanner, provided by Google Play services (see Third parties).

7. Third parties

Nexo does not share data with third parties. The only outside component involved is on Android: the pairing-code scanner is Google’s code scanner from Google Play services. It reads the code on your phone and is governed by Google’s Privacy Policy. Nexo receives only the text of the code, not the camera image.

Apple and Google process app downloads and updates under their own policies. We do not receive your personal data from them.

8. Security

No system is perfectly secure. Keep your devices updated and only pair devices you own. If you think you have found a security problem, please email [email protected].

9. Your choices and deleting data

Because we hold no data about you, there is nothing for us to delete on our side.

10. Children

Nexo is a general utility and is not directed at children. We do not knowingly collect personal information from anyone, including children.

11. Your rights

Depending on where you live (for example under the EU/UK GDPR, India’s Digital Personal Data Protection Act, or California law), you may have rights to access, correct, delete or port your personal data, or to object to its processing. Since we do not collect or hold your personal data, these requests have nothing to act on, but you are welcome to contact us at the address below with any question or request and we will answer it.

12. Changes to this policy

If we change how Nexo handles data, we will update this page and the dates at the top before the change takes effect, and we will highlight significant changes in the app’s release notes.
