SNMP Taskbar
Summary
SNMP Taskbar is a local network monitoring utility. It operates entirely on your Mac and communicates only with the network devices you configure. The developer does not receive any data from the app — not telemetry, not crash reports, not usage statistics, not configuration data.
What is stored locally
SNMP Taskbar saves its settings in macOS user defaults on your Mac. This includes:
- Router hostnames or IP addresses you enter.
- Interface names selected from discovery results.
- Display names, icons, smoothing settings, visibility settings, and alert thresholds per interface.
- App preferences: rate unit, graph scale, menu bar density, and Dock visibility.
- Network throughput history, if you enable Save history between launches in Settings — stored as local files in the app's Application Support folder; disabling the setting stops saving and deletes existing history files.
The SNMPv2c community string and, for SNMPv3 devices, the authentication and privacy passwords you enter are stored in the macOS Keychain, not in user defaults, and are only written when you click Save in Settings. If a Keychain write cannot be verified, the affected router's secret is instead retained in user defaults rather than lost — this is the only case where a secret is stored outside the Keychain.
This data remains on your Mac. It is not uploaded to any server or cloud service. It follows normal macOS user defaults behaviour — it may be included in Time Machine backups or Migration Assistant operations if your Mac is configured for those.
Network communication
SNMP Taskbar makes outbound network connections only to the devices you have configured:
- It sends SNMPv2c or SNMPv3 GET and WALK requests to UDP port 161 on your configured devices, using the version and credentials you configure per device.
- These requests are used to read interface names during discovery and to read traffic counters during monitoring.
SNMP Taskbar does not make any other network connections. It does not contact the developer's servers, Apple's servers (other than standard macOS system calls), analytics providers, advertising networks, or any other third party.
Logs and diagnostics
SNMP Taskbar writes router-specific connection and polling diagnostics to Apple's local Unified Logging system. These logs are stored by macOS on your Mac under the subsystem identifier ca.slepp.snmp-taskbar. You can read them with Console.app or the log command.
Diagnostic logs are not sent to the developer automatically or in any automated way. If you contact support, you may choose to copy and share relevant log output.
Notifications
If you enable alert thresholds for an interface, SNMP Taskbar may post local macOS notifications when traffic crosses that threshold. These notifications are processed entirely by macOS. SNMP Taskbar does not use a push notification service, cloud relay, or any external service to deliver notifications.
Analytics and tracking
SNMP Taskbar contains no analytics SDKs, advertising SDKs, crash-reporting services, or any other third-party code that makes network calls. There is no tracking of how the app is used.
This website and Cloudflare
The SNMP Taskbar website (snmp-taskbar.slepp.ca) is delivered by Cloudflare's content delivery network. When you visit this site, Cloudflare necessarily processes ordinary network metadata — including your IP address, request headers, and requested URLs — as part of delivering the page to you. This is standard for any CDN-delivered website. Cloudflare's privacy practices are described at cloudflare.com/privacypolicy/.
This website itself sets no cookies, uses no analytics, and makes no tracking calls of its own.
App Store privacy details
When distributed through the Mac App Store, Apple's own privacy practices apply to the purchase and download process. SNMP Taskbar's App Store privacy nutrition label declares no data collection by the developer.
The app runs in the macOS sandbox. It is granted the network client entitlement required for UDP SNMP request/response traffic. This entitlement allows general outbound network access; SNMP Taskbar uses it only to communicate with the SNMP devices you configure. The app does not hold the network server entitlement and never listens for inbound connections.
Privacy contact
For questions about this privacy policy or how SNMP Taskbar handles data, contact the developer through the support page.
