Privacy Policy — KN Network Toolkit
Effective date: October 22, 2026
KN Network Toolkit (“the app”) is published by Thomas Ntais (“we”, “us”, “our”) on the App Store (iOS) and on Google Play (Android). This policy explains what data the app handles when you use KN Network Toolkit on iOS or on Android.
1. In short
KN Network Toolkit has no server, no account, no advertising and no analytics, and it contains no tracking or advertising SDKs. We do not collect your name, email, contacts, device identifiers or any other personal information, and we do not receive anything you do in the app. The app talks to your own network and to the computers and services you choose to use. The parts that involve the internet are listed in section 3.
2. Data that stays on your device
- Network scan — the app scans your local Wi-Fi network (the same network as your device) to find devices and the services they offer. The list of devices it found (address, name, open ports) is kept on your device, per network, for up to 14 days, so the app can show devices that did not answer this time. It is never uploaded.
- Saved passwords — if you turn on saving a password (SMB or SSH), it is stored encrypted on this device only: in the iOS Keychain (not in iCloud Keychain) on iPhone and iPad, or encrypted with a key in the Android Keystore on Android. It needs Face ID, your fingerprint or face, or your device passcode / screen lock to be read. You can remove it in the app with “Forget saved password”.
- SSH keys — keys you create or add in the app are stored on this device in the same protected way, behind Face ID or your passcode on iOS, and your fingerprint, face or screen lock on Android. The public part, which you can copy, is kept with the app’s data.
- Face ID, fingerprint and screen lock — handled entirely by iOS or Android. The app only learns whether the check succeeded and never receives any biometric data.
- Your lists and settings — the computers you added to Monitor, the devices you saved for Wake-on-LAN, the last SSH host and user name you used, and the fingerprints of SSH servers you trusted are stored on this device.
- Wi-Fi network name — iOS and Android show the name of your Wi-Fi network only to apps that have location permission. If you allow it (only when you tap “Show network name”), the app reads the name to display it in “Wi-Fi info”. Your location is not read, used or stored. You can use the rest of the app without it.
- Notifications — Monitor can send local notifications on your device when a computer or service goes down or comes back. They are created on the device, and the system asks your permission first (on Android 13 and newer only when you turn the option on). No notification server is used.
- Files you open — files from a shared folder that you open are copied to a temporary folder on the device and deleted when you disconnect.
3. When the app uses the internet or other computers
The app sends data only when you use a tool that needs it, and only to the address that tool is for. We do not operate these services and we do not receive the data.
- Tools that connect to a computer you enter (Ping, Traceroute, Port scan, SSL/TLS certificate, HTTP client, SSH, Telnet / raw TCP, SMB shared folders, Wake-on-LAN, Monitor): the app connects to the host you typed, and what you send goes to that host. Telnet, plain TCP and plain http:// are not encrypted. Passwords you type there are sent as you typed them. Use SSH or https whenever you can.
- Whois / IP info — the app asks ipwho.is (location and network owner of an IP address) and rdap.org (registration data, which forwards the question to the registry responsible for the address or domain). They receive the address or domain you look up. If you leave the field empty, ipwho.is sees your own public IP address, because that is how it answers “my address”. For a domain name, the name is also resolved with your device’s normal DNS, and the resulting address is looked up.
- Speed test — with “Internet”, the app downloads and uploads test data to speed.cloudflare.com (Cloudflare). Cloudflare can see your public IP address and the amount of data. With “Your server”, it uses the server you type. The Internet test uses a lot of data (hundreds of megabytes), so use Wi-Fi.
- DNS lookup — the name you look up is sent to the DNS server you pick: Cloudflare (1.1.1.1), Google (8.8.8.8), Quad9 (9.9.9.9) or one you type.
These services have their own privacy policies, which apply to the data they receive: Cloudflare (cloudflare.com/privacypolicy), Google (policies.google.com/privacy), Quad9 (quad9.net/privacy/policy), ipwho.is and the registries behind rdap.org.
4. Open source libraries
The app contains open source libraries (listed in the app, under Tools → About → Open source licenses). They run inside the app and do not send data anywhere.
5. Deleting your data
On iOS, remove saved passwords and SSH keys inside the app before you delete it: iOS can keep Keychain entries after an app is removed. On Android, uninstalling the app removes everything it stored, including saved passwords and keys. Deleting the app removes the lists and settings stored with it.

6. Children's privacy
KN Network Toolkit does not collect personal information from anyone, including children.
7. Changes to this policy
We may update this policy from time to time. Changes will be posted on this page with an updated effective date.
