Network Toolkit works entirely on your device. There is no account, no server and no cloud sync. The app does not send information about you or about your network to us or to anyone else. We do not operate a backend for this app, and we have no way to see your data. The free version shows ads through Google AdMob, which collects its own advertising data; that is set out in full under "Advertising" below. Two features you start yourself — the internet test and the speed test — contact public servers on the internet; that is set out under "Internet and speed tests" below. The connection tools (SSH, Telnet, HTTP, TLS, DNS, traceroute and the socket consoles) connect only to the addresses you type in; see "Tools that connect where you ask".
This app is developed and published by DLL Soft. For any privacy question, contact us at levi@fiscaltaskforce.ro.
To do its job, the app reads technical information about the local network your phone is connected to:
All of it is generated by you, on demand, and it stays on your phone. The one exception is advertising in the free version, which is described further down.
Everything the app produces is written to a SQLite database inside the app's private storage area on your device. No other app can read it. Nothing is uploaded, backed up to our servers, shared or sold, because there are no servers involved.
Passwords and private keys you choose to remember for SSH are encrypted with the Android Keystore, are never written to the history and are deleted together with the saved target. Bluetooth devices seen during a scan are kept in memory only, unless you save one.
The app does not request access to contacts, phone, SMS, camera, microphone, personal files or background location.
The app scans only the local IPv4 subnet your device is connected to. It does not scan public internet address ranges, and that behaviour is not implemented in the app. It is a diagnostic tool intended for networks you own or are authorised to inspect.
The connection tools reach a host outside your network only when you type its address and start the tool. They diagnose; they do not attempt to exploit or break into anything.
Network Toolkit is a technical utility intended for users aged 18 and over. It is not directed at children, and it collects no personal data from anyone, regardless of age.
Because none of your data ever reaches us — the internet and speed tests carry no data about you or your network, and what you send through a connection tool goes only to the host you chose — there is nothing for us to export, correct or delete on your behalf under GDPR or similar laws. You already hold all of it.
When the Pro version becomes purchasable, it will be a one-time purchase processed by Google Play. Payment is handled entirely by Google. We never see your card details or billing information, and Google's own privacy policy applies to that transaction.
The free version of the app shows ads supplied by Google AdMob. Nothing about your network is used to target them: the scan results, device list, IP and MAC addresses and monitoring history never leave your phone and are never sent to Google or to any advertiser.
To serve ads, the Google Mobile Ads SDK collects and processes data on its own, independently of the rest of the app. That typically includes your device's advertising ID, coarse device and app information, and your IP address as seen by Google's servers. Google acts as an independent controller for that data. Their practices are described in the Google privacy policy and in the AdMob documentation.
If you are in the European Economic Area, the United Kingdom or Switzerland, the app shows a consent form before the first ad request, using Google's User Messaging Platform. You can change that decision at any time from Settings → Ad privacy options. You can also reset your advertising ID, or opt out of ad personalisation entirely, from your Android system settings.
Buying the Pro version removes every ad, and with it every ad-related data collection.
Two features reach outside your local network, and only when you start them yourself:
1.1.1.1 (Cloudflare) and, if that fails, to 8.8.8.8 (Google), and
resolve one public hostname. Nothing is sent beyond the connection itself.
speed.cloudflare.com) and times the transfer. The uploaded data
is random filler generated on the device — it contains nothing about you, your files or your
network. Cloudflare sees your public IP address for the duration of the test, exactly as any
website you visit does, and their own privacy policy applies to that request. Their response
also volunteers your public IP and an approximate location derived from it; the app reads
neither. It keeps only the AS number of your provider and the code of the datacenter that
served the test, and writes those, with the measured speeds, to the local database on your
phone and nowhere else.
Neither feature sends your device list, scan results, MAC addresses, hostnames or monitoring history anywhere. Both are off unless you tap them, and the speed test asks for confirmation first when you are on mobile data, because it uses a measurable amount of your data allowance.
SSH, Telnet, the TCP and UDP consoles, the HTTP client, the TLS inspector, DNS lookup, traceroute and the IoT tools (MQTT, Modbus TCP and SNMP) connect only to the addresses you enter, and only when you connect or run them. What you type into them is sent to that host and nowhere else. In addition:
1.1.1.1), Google
(8.8.8.8) or Quad9 (9.9.9.9) when you select them.1.1.1.1,
8.8.8.8 and Cloudflare's connectivity check (cp.cloudflare.com).Apart from Google AdMob in the free version, the public servers named above and the hosts you choose to connect to yourself, the app contains no analytics SDK and no crash-reporting SDK. No other third party receives any data from this app.
If the app ever starts doing something that changes what is written here, this page will be updated and the date at the top will change. Material changes will also be noted in the release notes on Google Play.
