Privacy policy

Local only, by default

Everything the app measures about your PC is stored on your PC and stays there. No measurement, statistic or list of programs is uploaded unless you explicitly enable a sharing feature.

The one connection the app makes by default is the daily update check below. It sends the version number and, unless you turned it off, a random install ID. The install ID counts as personal data: it is persistent, and it may be linked to an account if you have one. This page says exactly what it is, what the server keeps, and how to turn it off.

The update check

Once a day, the app asks its update server whether a newer version exists. Only if that server cannot be reached, or gives no valid answer, it asks the backup update server, on a separate domain, the very same question. It is on by default, and you can turn it off in Settings.

What is sent

One HTTPS request containing the app's version number, for example 1.2.0, and, unless you turned it off, this PC's install ID, a random number created on this PC, for example 4f1c2a9e0b7d4c31a8e5f60291d3b7ac.

The install ID is not derived from your hardware, your name or anything else. It lets us count how many installs are in use, and it is how an account you create later would find this PC.

Nothing else is sent: no OS version, no hardware details, no usage data, no list of programs, and no cookies. Like any request on the internet, it reveals your IP address and the time.

What the server keeps

• The web server's access log (IP address, time, the requested address) for 30 days, to keep the site running and to stop abuse, then deleted.
• For counting installs: the install ID, the day it checked, its version and channel, and the country it checked from, for 90 days, then only totals. The country is looked up from the IP address when the check arrives, and the IP address is not kept with it.

None of this is shared or sold.

Your install ID

The installer shows it with its own checkbox, separate from the licence agreement and ticked to start with. You can untick it before installing, and installing works either way.

Settings shows the ID and lets you turn it off, or on again, at any time. "New ID" replaces it with a new random one, after which the server sees this PC as a new install. With it off, the check sends the version only. With update checks off, nothing is sent at all. Uninstalling the app deletes the ID from this PC.

Accounts

If you create an account and sign in from the app, your account is linked to this PC's install ID. That link is only ever made by signing in, never by matching other data.

How to turn it off

In Settings, "Check for updates automatically". With it off, the app makes no network connections at all.

Administrators can turn it off machine-wide with the policy value HKLM\SOFTWARE\Policies\PcHealth\DisableUpdateCheck = 1.

Installing an update

An update installs by itself, in the background, unless you turned that off. The installer asks with its own checkbox, ticked to start with, and Settings changes it at any time. You can also press Install to install at once.

Either way the app asks again and downloads the installer from the update server that answered. That request contains the installer's address and nothing else. The file is installed only if it is exactly the version that was published, and the automatic install waits until no window of the app is open.

Which program connects, and where

Only PcHealth.Updater.exe, and only to the app's two update servers: pchealthcontrol.com and, only as a backup, onlinepcmon.xyz. The monitoring service, PcHealth.Service.exe, never connects to the network.

This website is a separate domain, mypc.health, that the program never contacts.

Legal basis

Consent (GDPR art. 6(1)(a); ePrivacy art. 5(3) for reading the ID from the device), given in the installer by its own checkbox with its own explanation, never bundled into the licence agreement. The box is ticked to start with. It can be unticked there, turning it off changes nothing else, and it can be turned off in Settings at any time.

What is stored on your PC

The app keeps technical data about your PC, on your PC, for your own use. For example:

• CPU usage
• Memory usage
• Disk activity
• Process names
• Executable paths
• Network usage totals, for the machine and per application (bytes in and out, nothing else)
• Whether the PC was locked or signed out at each sample: yes or no, never who, and never keyboard or mouse activity
• Startup entries
• Boot times
• Temperature readings
• Crash events: application crashes and hangs as Windows recorded them in its own Application log (which program, when, and for a crash the exception code and faulting module), read locally

What per-application network use does and does not record

Per-application network use comes from the Windows kernel's TCP/IP events, and those events carry more than a byte count: the remote address and port of every connection. The service reads the process ID, the size, and whether the connection is loopback, and nothing else. Addresses, ports and host names are never stored, logged or kept in memory past the event, so the app can say how much an application sent, never where it sent it.

What it does not collect

• File contents
• Personal documents
• Browser history
• URLs
• Emails
• Chat messages
• Keystrokes
• Screenshots
• Clipboard contents
• Passwords or tokens

Community Insights

Settings has a choice to share anonymized, aggregated statistics for public reports about real-world Windows performance. It is off unless you turn it on. In this version, data sharing is not implemented: nothing is sent whatever you choose, and the setting only records your choice for a future release. Opting in is never required for anything else in the app.

Reporting a problem

Settings, "Report a problem", gives an email address and a "Copy diagnostics" button. The app sends nothing itself:

• The address opens your own mail program. The app makes no connection.
• The diagnostics are shown in full on the screen before the button copies them. They go to the clipboard, and leave the PC only if you paste them into a message.
• They contain the app and Windows versions, the core count, the service's own measurements (CPU, memory, disk writes, database size) and its last ten warnings and errors from the Event Log, first line only. They contain nothing about what you run: no process list, no application names, no paths except the app's own. Your profile path and name are replaced where a log line would carry them.

This website sets no cookies, runs no analytics, and loads nothing from any other site. The download button takes you to the update server, pchealthcontrol.com, which serves the installer.
