Nexoniq

Quietly watching
your network.

Nexoniq keeps an eye on your local network and the services you care about: a presence matrix, per-device alerts, and uptime history. Everything stays on your Mac.

— How it works —

The whole subnet, at a glance.

A 256-cell grid maps every IP address on your local network. Green means online, amber means seen recently, coral means offline. The map fills as Nexoniq scans.

Below it, devices group themselves into categories — routers, computers, mobile, services, media. Click a device to see its 7-day presence history as a matrix.

— What it does —

Six things, done well.

Nexoniq does one job: it tells you what's up and what isn't on the network you live on.

/01

Presence matrix

Seven days of history drawn as a tight grid of 30-minute cells, so you can see exactly when a device dropped and for how long.

/02

Per-device alerts

Toggle alerts on per device or service. macOS notifications fire when something goes offline, comes back, or stays down. Transient flapping is filtered out before it reaches you.

/03

Uptime, measured

24-hour, 7-day and 30-day percentages computed from what Nexoniq actually observed. If the data is partial, the value shows “—” rather than a guess.

/04

Service-only mode

Running on a network you can't probe? Switch to service-only mode and Nexoniq watches only the URLs and host:port endpoints you list.

/05

Reorderable categories

Network, Computers, Mobile, Services, Media, Storage, Security. Drag them into your own order. Collapse the ones you don't need every day.

/06

Light & dark, always

The palette (teal, amber, coral) recalibrates between modes, so contrast stays right whether your wallpaper is paper-white or midnight.

— Philosophy —

A network monitor should tell you the truth about your network, and keep what it learns to itself.

— How Nexoniq thinks
— Who it's for —

Built for people who run their own things.

The home-lab tinkerer

You run a pfSense box, a NAS, a couple of access points, maybe a Pi or two. Nexoniq gives you a single window onto whether all of them are still where you left them.

The remote-service watcher

You care less about the LAN and more about whether your VPS, your mail server, and your status page respond. Service-only mode skips the local scan entirely and checks just those.

The privacy-minded

You want your network map to stay yours. Nexoniq stores everything locally on your Mac; there is no Nexoniq server.

— The promise —

One small monthly subscription.

A monthly fee, billed through the App Store.

The privacy policy.

Last updated · 28 April 2026

Nexoniq is built so that what's on your network stays on your network. This policy describes exactly what happens on your Mac, what leaves it, and what we do not collect.

What stays on your Mac

All your monitoring data lives locally on your Mac, in ~/Library/Application Support/Nexoniq. Nothing is transmitted to a Nexoniq server at any point during normal use, because there is no Nexoniq server.

  • Discovered devices — IP addresses, MAC addresses, hostnames, OUI vendor lookups
  • Configured services — the URLs and host:port endpoints you choose to monitor
  • Presence history — which devices and services responded, and when
  • Alerts — your per-device alert configuration and trigger history
  • Preferences — sweep interval, notification hours, category order, display name overrides, notes

OUI vendor lookups are performed against a local database file shipped inside the app. No vendor query is sent over the network.

What we don't collect

Nexoniq contains no analytics, trackers, third-party SDKs, advertising identifiers, or crash-reporting services.

We do not know how many devices you monitor, which alerts fire, how long you keep the app open, or whether you opened it today. There are no accounts, so there is nothing to associate with you in the first place.

This is verifiable. Nexoniq's App Privacy label on the Mac App Store shows "Data Not Collected" across every category. Apple enforces this label; if Nexoniq contained a tracker, it would show up there.

What leaves your Mac

For Nexoniq to work, your Mac must send packets on the local network and HTTP requests to configured service endpoints. Specifically:

  • ICMP and TCP probes on the IP ranges you've configured. These stay on your local network.
  • HTTP/HTTPS requests to monitored service URLs. The service host sees your IP address and a standard request, just like a browser. Nexoniq is not a middleman.
  • TCP connect attempts to monitored host:port endpoints. The destination receives a connection attempt, no more.
  • mDNS queries, if discovery is enabled, broadcast on the local link only.

Service-only mode restricts this further, to only the endpoints you've listed.

When you send feedback

Nexoniq does not contain a feedback form. If you'd like to send a comment, bug report, or feature request, send a regular email to hello@nexoniq.app using whichever email program you prefer.

The address is the only way to reach the author. Your email lands in a personal inbox and is usually answered within a few days.

If you'd like to include diagnostics, you may attach the debug log from ~/Library/Application Support/Nexoniq/nexoniq-debug.txt (structural events only; it contains no monitored hostnames or IPs). Attaching anything is entirely your choice; Nexoniq does not collect or upload diagnostics on its own.

Children's privacy

Nexoniq does not knowingly collect any information from anyone, including children. The app has a 4+ age rating on the Mac App Store, has no accounts or social features, and contains nothing directed at children.

Changes to this policy

If this policy changes materially, the updated version will be posted here with a new "last updated" date. Because Nexoniq does not have your email address or any way to contact you, we cannot notify you directly. You're welcome to bookmark this page and check back now and then.
