Does TaskSlinger Collect Telemetry or Send Data Anywhere?

Updated

No. According to the TaskSlinger website, the app "sends no telemetry, analytics, or usage data anywhere." That statement covers the tool's own behavior, not Windows itself — the operating system and any other software you run can still phone home independently. The claim applies to the current free beta, version 0.9.5 for Windows 10/11 x64.

What the no-telemetry claim covers

The site lists three specific categories it says are never transmitted:

  • Telemetry
  • Analytics
  • Usage data

It also states there is "no phoning home," which in practice means the app does not check in with a vendor server during normal use. The site does not publish a network-audit report, packet log, or third-party privacy certification, so the claim rests on the developer's own description. If you need proof rather than a statement, monitor the app's outbound connections yourself after installing (see the verification steps below).

Why the architecture matters for privacy and weight

TaskSlinger is written in native C with a custom Direct3D renderer and its own UI framework. The site explicitly says it is "not an embedded web view or a React Native application." That distinction is relevant to both privacy and resource use:

  • Fewer moving parts. No embedded browser engine means no browser-style background services or update pings bundled in.
  • Small footprint. The download is listed at 2.1 MB.
  • Fast start. The site claims a 150-millisecond launch, fully rendered from the first frame.

These are design goals stated by the developer, not independently benchmarked figures. Treat the 150 ms number as a vendor claim until you time it on your own machine.

What TaskSlinger does locally

The app is a system monitor and control tool. Its views — Processes, Performance, Services, Startup Apps, Connections, and Information — read local system state. The Connections view shows local and foreign endpoints, state, process ID, and owning process, which is useful context: the tool can show you what other programs are connecting to, even though it says it makes no connections of its own.

Beyond monitoring, the site describes deeper actions: viewing process modules and tokens, dumping processes, and managing services and startup items.

How to verify the no-telemetry claim yourself

  1. Install the beta from the official site (0.9.5, Windows 10/11 x64).
  2. Open TaskSlinger's own Connections view and locate the TaskSlinger process. Expect no foreign endpoints under normal use.
  3. Cross-check with a second tool. Use Windows Resource Monitor (Network tab) or a packet capture tool, filtered to the TaskSlinger process, while you browse its views and change settings.
  4. Watch during startup and shutdown, since check-in behavior often hides at launch.
  5. Repeat after any update, because a new build can change behavior.

Expected result if the claim holds: no outbound traffic to a vendor domain. If you see connections, note the endpoint and state before drawing conclusions — some traffic may belong to Windows components the app queries rather than the app itself.

Beta status and what to weigh before installing

The site labels 0.9.5 as beta software that "may contain bugs or behave unexpectedly" and advises using it at your own discretion. Two practical implications:

  • Privacy posture vs. stability. A clean network profile does not guarantee a stable app. If you rely on a task manager during incidents, keep the built-in Windows Task Manager available as a fallback.
  • Licensing. The free beta is stated to remain available until version 1.0, with a perpetual license offered for purchase afterward. The site links to a pricing page; specific prices are not stated in the material reviewed here, so check that page directly rather than assuming cost or free-forever terms.

Bottom line

If your concern is whether TaskSlinger itself ships telemetry, the developer's answer is a clear no — no telemetry, analytics, or usage data, and no phoning home — backed by a native, non-web-view design and a 2.1 MB footprint. Because that is a self-reported claim on beta software, the deciding factor for privacy-sensitive users is a short verification pass with a network monitor after install.
