This Privacy Policy explains how NetworkJee ("the app") handles information when you use it.
Summary
NetworkJee is a local Windows network diagnostics and configuration app. It does not require an account and does not contain advertising, analytics, telemetry, or third-party tracking. The publisher does not operate a server for the app and does not receive your diagnostic results, local network scan results, reports, settings, or logs.
NetworkJee does send network traffic when it performs diagnostics, shows your external IP address, runs a speed test or DNS benchmark, checks devices on your local network, scans the ports of a device on your network, wakes a device, checks a website's certificate, downloads a public manufacturer list, changes your DNS or IP settings, or uses a network tool at your request. Packet capture, which you can start yourself, records traffic on this PC but sends nothing anywhere; captured packets are never sent to the publisher. The destination service or network operator can receive ordinary connection information, such as your public IP address, request time, protocol, and the data required to answer the request.
Information processed on your device
To provide its features, NetworkJee reads and processes the following information locally:
- Network adapter names, descriptions, identifiers, status, link speed, and interface indexes.
- Local IPv4 and IPv6 addresses, subnet information, gateways, DNS server addresses, and MAC addresses.
- Results from connectivity checks, ping, traceroute, TCP port tests, DNS lookups, and the Cloudflare speed test.
- IP and MAC addresses discovered through a scan of the selected local IPv4 network.
- Hostnames, IP addresses, ports, and DNS record types that you enter into the network tools.
- Your external (public) IPv4 and IPv6 address as reported back by Cloudflare, shown on Home.
- DNS benchmark timings for the DNS servers tested.
- For the home network security check: the name (SSID) and security type of the current Wi-Fi network, the manufacturer, model, version and similar details that local devices publish about themselves through UPnP, and which of a short list of ports are open on local devices.
- For network alerts, while NetworkJee runs (also in the notification area): whether Windows reports internet access, the adapters' addresses, gateways and DNS servers, and the name (SSID) and security type of the current Wi-Fi network. These are compared with the previous check on this PC only, to show alerts such as "connection lost" or "open Wi-Fi"; NetworkJee sends no traffic of its own to produce them and does not keep a history of networks.
- For IP profiles: the adapter's current IPv4 address, subnet, gateway and DNS settings, and whether they come from DHCP.
- For the port range scan and the TLS certificate check: which ports of the device you chose accept connections, and the certificate the server presents (names, issuer, validity and the negotiated TLS version).
- For packet capture, only while a capture you started is running: the network packets of this PC that match the filter you chose. Packets can contain the names of sites this PC looks up, the addresses it talks to and, for unencrypted connections, their contents. They are kept in the app's memory, are forgotten when you leave the page or close the app, and are written to a file only if you select Save.
- The computer name when a diagnostic report is created.
This information is used to display results, perform the action you request, create a local report, and restore network settings. NetworkJee does not automatically upload it to the publisher.
Network connections and third-party services
NetworkJee makes the following connections for specific features:
| Feature | Destination | Purpose and information sent |
|---|---|---|
| Automatic diagnostics | www.microsoft.com, 1.1.1.1, and 2606:4700:4700::1111 |
Tests DNS, HTTPS, IPv4, IPv6, latency, and packet loss. Microsoft, Cloudflare, your DNS resolver, and network operators can receive ordinary connection metadata. |
| Cloudflare speed test | speed.cloudflare.com |
Measures latency, jitter, download speed, and upload speed. The test starts only after you confirm it and can transfer up to approximately 60 MB. Cloudflare receives the test traffic and ordinary connection metadata, including your public IP address. The measured result is displayed locally and is not sent to the publisher. |
| Ping, traceroute, TCP port test, and DNS lookup | The hostname, IP address, or service you choose; DNS requests use the resolver configured in Windows | The destination, DNS resolver, internet provider, and intermediate network operators can observe the traffic normally required for the selected test. |
| External IP address on Home | one.one.one.one (Cloudflare) over IPv4 and, when this PC has global IPv6, over IPv6 |
Each time Home checks the connection, NetworkJee asks Cloudflare which public address the request came from, so it can show the external IP address. Cloudflare receives ordinary connection metadata, including that public IP address. The address is only displayed; it is not stored or sent to the publisher. |
| DNS benchmark (Premium) | Your current DNS servers, the Cloudflare, Google Public DNS, and Quad9 server addresses listed in the app, and any DNS servers you add to the benchmark | Starts only when you select Run benchmark. Sends a few hundred small DNS queries (under 100 KB in total) for a fixed list of popular website names and random test names that do not exist. It never uses your browsing history. The DNS servers and network operators can receive ordinary connection metadata, including your public IP address. Results are shown locally and not saved or sent to the publisher. |
| Home network security check (Premium) | Devices on your local network only | Starts only when you select Run security check. NetworkJee finds devices with the same local scan as "Devices on my network", sends a standard UPnP discovery request (the one Windows network discovery also uses) and reads the description each responding device publishes about itself, and tries a plain TCP connection to a short list of ports (for example Telnet, FTP, VNC and Remote Desktop) on each device. Connections are closed immediately: no passwords are tried, nothing is changed on the devices, and nothing is sent to the internet. The Wi-Fi security type is read from Windows. Results are shown locally and are not saved or sent to the publisher. |
| Wake-on-LAN (Premium) | Your local network only | Starts only when you select Wake. NetworkJee sends a standard wake-up packet ("magic packet") containing the device's MAC address as a broadcast on the selected adapter's own subnet, and, if you saved the device's IP address, pings it for up to a minute to see whether it woke up. Nothing is sent to the internet. |
| Port range scan (Premium) | One device on your local network that you choose | Starts only when you select Scan. NetworkJee opens and immediately closes a TCP connection to each chosen port (at most 1,024) on a device with a private address; it sends no data and tries no passwords. Addresses on the internet are refused. Results are shown locally and saved only if you export them. |
| TLS certificate check (Premium) | The website or server you enter | Starts only when you select Check certificate. NetworkJee opens a connection and completes a TLS handshake to read the server's certificate, then closes it without sending any data. If you choose to check revocation, Windows also contacts the certificate authority's revocation (OCSP/CRL) servers named in the certificate. The server and those services receive ordinary connection metadata, including your public IP address. Results are shown locally and not saved. |
| Packet capture (Premium, preview) | Nothing is sent: it records traffic this PC already sends and receives | Starts only after you confirm a dialog and Windows asks for administrator permission. Windows' built-in Packet Monitor records the network packets of this PC that match the filter you choose (by default only DNS lookups), for at most 5 minutes and 100 MB. Packets can contain private information such as the names of sites this PC looks up and the contents of unencrypted connections. They are kept only in the app's memory, are forgotten when you leave the page, and are written to a file only when you select Save. NetworkJee never sends them anywhere. |
| MAC manufacturer list update | Public IEEE Registration Authority CSV files at standards-oui.ieee.org |
Downloads manufacturer registration data when you select the update action. NetworkJee does not send discovered MAC addresses to IEEE. Manufacturer matching happens locally. |
| DNS provider selection | Cloudflare, Google Public DNS, Quad9, or a custom provider you enter | NetworkJee changes the selected Windows adapter's DNS settings. After the change, Windows and other apps may send their DNS queries to that provider. NetworkJee does not proxy, inspect, or keep a history of those DNS queries. A VPN, browser secure DNS setting, or another adapter may use a different resolver. |
The third parties process traffic under their own terms and privacy policies:
- Microsoft Privacy Statement
- Cloudflare Privacy Policy
- IEEE Privacy Policy
- Google Privacy Policy
- Quad9 Data and Privacy Policy
If you choose a custom target or DNS provider, review that party's privacy policy separately.
Local storage and retention
NetworkJee stores the following data only in the app's local Windows data area. The exact path can vary depending on how the app was installed.
Diagnostic logs
The app and its elevated helper write daily diagnostic log files. Logs can contain timestamps, app operations, error messages, exception details, network addresses or hostnames involved in an error, adapter details, and local file paths. They do not contain packet contents, browsing history, or a history of DNS queries. For a packet capture, the logs record only the filter you chose, how long it ran and how many packets were captured.
Log files older than 14 days are deleted automatically when the logger starts. Cleanup is best effort, so a file that is locked or cannot be accessed may remain until it can be removed. Logs are never automatically sent to the publisher or another party.
DNS restore information
Before NetworkJee changes DNS settings, it can save a local, adapter-specific restore point. It contains the adapter identifier and interface index, the previous IPv4 and IPv6 DNS server addresses, and whether each protocol used automatic or manual DNS configuration. The restore point can remain across app restarts and is removed for that adapter after a successful restore.
MAC manufacturer data
If you update the manufacturer database, NetworkJee stores local copies of the public IEEE MA-L, MA-M, and MA-S lists. The app uses these files to match MAC address prefixes locally. They remain until replaced by a later update or removed with the app's local data.
DNS benchmark servers
If you add your own DNS servers to the DNS benchmark, NetworkJee saves up to five of those IP addresses locally so they are included next time. Benchmark results are not saved. You can remove a server from the list at any time.
Wake-on-LAN devices
Devices you save for Wake-on-LAN (Premium) are stored locally: the name you give them, their MAC address, their last known IP address if you entered it, and the network adapter they were saved on. You can delete a device in the app at any time.
IP profiles and app preferences
IP profiles you save (Premium) are stored locally: the profile name, the adapter it belongs to, and the IPv4 address, subnet, gateway and DNS servers you entered. Before NetworkJee first changes an adapter's IP settings, it saves that adapter's previous IPv4 setup as a local restore point, which is removed after a successful restore. NetworkJee also saves your notification-area and alert choices locally. You can delete profiles in the app; all of this is removed with the app's local data.
Captured packets
Packets from a packet capture are not stored by NetworkJee. They stay in memory while the Packet capture page is open and are discarded when you clear them, leave the page or close the app. If you select Save for Wireshark, the packets are written to a pcapng file in the location you choose; that file is not encrypted and you control where it is kept and shared.
Premium purchase status
NetworkJee Premium is an optional one-time in-app purchase. The purchase and payment are handled entirely by the Microsoft Store under Microsoft's terms and privacy statement; NetworkJee never receives your payment details. The app asks the Microsoft Store whether Premium is owned by the signed-in Store account. After a confirmed purchase it saves only the date and time of the last confirmation locally, so Premium keeps working for up to 30 days if the Store temporarily cannot be reached. The file is deleted when the Store reports that Premium is not owned.
Reports and clipboard data
Diagnostic reports are created locally. Redaction is enabled by default and replaces known values such as the computer name, MAC address, and the selected adapter's IP, gateway, and DNS addresses. Public test destinations may remain visible because they are not specific to your device.
You may turn redaction off after a warning. NetworkJee copies a report to the Windows clipboard or saves it as a TXT or JSON file only when you request that action. You control the saved file and where it is shared. Other apps may be able to read clipboard contents according to Windows behavior and their permissions.
Permissions
The app package declares internet access and private network access so it can run the network tests, local network scan and home network security check described above. It also supports full-trust desktop execution. NetworkJee does not request location access; if a Windows version shares Wi-Fi details only with apps that have location access, the security check reports that the Wi-Fi security could not be read. NetworkJee starts its elevated helper and displays a Windows User Account Control prompt only when an action needs administrator rights, such as changing DNS or IP settings, renewing DHCP, restarting an adapter, or running a packet capture. The elevated helper performs that one action and exits; a packet capture ends after at most 5 minutes or 100 MB, when you stop it, or when you close NetworkJee. If you turn on "Start with Windows", NetworkJee starts in the notification area when you sign in; this is off by default.
Security
Web requests to Microsoft, Cloudflare, and IEEE use HTTPS. Other diagnostic protocols, including ICMP ping, traceroute, DNS, a TCP port connection, and the UPnP discovery and device descriptions used by the security check within your local network, use the protocol required by the selected test and are not necessarily encrypted. Information that local devices return is treated as untrusted and read only from the device that answered. Local app data is stored under the current Windows user profile or app container and is not protected with separate app-level encryption.
What NetworkJee does not collect
NetworkJee does not:
- Create a user account or collect your name, email address, payment information (Premium purchases are processed by the Microsoft Store), contacts, precise location, photos, or documents.
- Collect analytics, advertising identifiers, usage telemetry, or crash reports for the publisher.
- Record packet contents, browsing history, or DNS queries on its own. Packets are recorded only during a packet capture you start and confirm, only in the app's memory, and never sent anywhere.
- Sell or rent personal information.
- Automatically upload local network scan results, reports, settings, or logs.
Your choices and deletion
You decide whether to run the speed test, the DNS benchmark, the home network security check, a port range scan, a TLS certificate check or a packet capture, update the IEEE manufacturer list, scan the local network, wake a device, use a network tool, change DNS or IP settings, copy a report, or save a report or capture. Network alerts, keeping NetworkJee in the notification area and starting it with Windows can each be turned off in Settings. The external IP address and the diagnostics on Home are checked automatically when Home runs its connection check. You can cancel supported long-running operations from the app.
You can remove NetworkJee's local data through Windows app reset or uninstall controls. You can also delete reports you saved and clear clipboard contents through Windows. Because the publisher does not receive app data, the publisher has no user data from the app to access, correct, export, or delete. Requests concerning data processed by a third-party service must be directed to that service.
Children's privacy
NetworkJee is a general-purpose network utility and is not directed to children. The publisher does not knowingly collect personal information from children through the app.
Changes to this policy
This policy may be updated when NetworkJee's features or data practices change. The current version will show a new effective date.
