Nexoniq

Quietly watching
your network.

Nexoniq shows what's online and what isn't, on your local network and at the services you care about. A presence matrix you can read in a glance, alerts that don't lie. All 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 rendered as a matrix.

— What it does —

Six things, done well.

Not an entire NMS. Not a cloud platform. A focused tool for one job: knowing what's up and what isn't on the network you live on.

/01

Presence matrix

A 7-day history rendered as a tight grid of 30-minute cells. You see uptime patterns the way the network actually behaved — not summarized into a single number.

/02

Per-device alerts

Toggle alerts on for any device or service. macOS notifications fire when something goes offline, comes back, or stays down — never on transient flapping.

/03

Uptime that's honest

24-hour, 7-day and 30-day percentages computed from observed data. No five-nines theatre — when data is partial, the value reads — instead of pretending.

/04

Service-only mode

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

/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

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

— Philosophy —

A network monitor should tell you what's true, not what's flattering. No vanity metrics, no dashboards-of-dashboards, no telemetry calling home.

— 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 scan and just watches what you list.

The privacy-minded

You don't want yet another tool that ships your data somewhere. Nexoniq stores everything locally. Nothing leaves your Mac. There is no Nexoniq server.

— The promise —

An honest monthly subscription.

A small monthly fee, billed through the App Store. No ads, no trackers, no upsells, no data on the side.

— Policy —

Privacy, plainly stated.

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. No trackers. No third-party SDKs. No advertising identifiers. No crash reporting services that phone home.

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 even if we wanted to.

This is verifiable. Nexoniq's App Privacy label on the Mac App Store shows "Data Not Collected" across every category. Apple enforces this — if Nexoniq contained any tracker, it would be listed 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 — they're not routed to Nexoniq.
  • 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.

Nothing is routed through a Nexoniq server. Service-only mode further restricts this to only the endpoints you explicitly 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 nexoniq@gpio.fi using whichever email program you prefer.

The address is the only way to reach the author. There are no support tickets, no chat widget, no third-party helpdesk. Your email lands directly in a personal inbox and is read by a person — usually 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 — 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 and contains no user accounts, no social features, and no content 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 periodically.
