Privacy Policy
Network Tools Privacy Policy
Effective date: October 28, 2026
Thank you for using Network Tools, provided by Licheng Tech. The app offers network status, Ping, DNS lookup, TCP connect and HTTP(S) check tools. Every check is started by you manually and nothing runs in the background.
This policy explains what information the app handles, where the network traffic from your checks goes, and how data is stored and deleted on your device. Please read it before use, especially Section 2 on network traffic.
In short
- No ads, in-app purchases or accounts; no advertising, analytics or crash-reporting SDKs
- Only two permissions: INTERNET and ACCESS_NETWORK_STATE
- Every check is started by you, time-limited and cancellable; nothing runs in the background
- Check traffic goes to the targets you enter and to your network's DNS servers, which may see your IP address and the queries
- The app itself sends nothing to the developer; up to 20 recent targets stay on your device and can be cleared in Settings
- The app opts out of Android cloud backup
1. Information we process
The app does not ask for your name, phone number, email or sign-in information, creates no accounts, and does not read contacts, location, photos, device identifiers or advertising IDs. It contains no advertising, analytics or crash-reporting SDKs. The developer cannot remotely read any of your data through the app.
When you run a check, the app reads network status information provided by Android and shows it on screen: connection type, whether Android has validated internet access, whether the connection is metered, IPv4/IPv6 addresses, DNS servers, gateway and routes, and Private DNS. Values Android does not provide are shown as unavailable. This information is only displayed to you and is not sent to the developer.
The hostnames, IP addresses, ports and URLs you enter, and the results of each check, are held in memory on your device to run the check and display it. You can copy results as text; the copied text is then handled by the system clipboard and whichever app you paste it into.
The app stores necessary settings such as your chosen interface language, and your recent targets (up to 20), on your device.
2. Where network traffic goes
Network Tools is a diagnostic tool, so the checks you start produce real network traffic. Ping sends ICMP packets to the target you enter through the system ping tool. DNS lookup sends queries to the DNS servers used by your current network. TCP connect tries to connect to the one host and port you specify, with no port-range scanning. The HTTP(S) check sends a request to the URL you enter and reads the status code, redirects, timing, TLS version and the certificate subject, issuer and expiry; certificate validation is never disabled.
This traffic is received by the targets you enter and passes through your network provider, router and the DNS servers you use. They can see your IP address, the names you look up and the destinations you contact, and handle them under their own policies. This traffic does not go through any developer server and the developer does not receive it.
Test only hosts and services you are entitled to test. Some networks block ICMP or particular ports, so a failed check does not always mean a target is unavailable.
3. Storage and deletion
Your recent targets (up to 20) and settings such as interface language are stored only in Android private app storage. They are not uploaded to any server, and there is no cloud sync or developer-hosted storage. You can clear recent targets at any time in the app's Settings.
The app opts out of Android cloud backup, and it has no automatic backup or export feature. Clearing app data or uninstalling the app deletes the recent targets and settings stored on your device, and we cannot recover them.
Result text you have copied to the system clipboard is not automatically removed when you clear recent targets or uninstall the app; manage it separately where you pasted it.
4. Permissions
The app declares only two permissions: INTERNET, to reach the network when you start a check, and ACCESS_NETWORK_STATE, to read the current network's connection type, validation, metered status, addresses, DNS and routes.
The app does not request location, camera, microphone, contacts, photo-library, notification, background-execution or accessibility permissions, and needs no root or ADB. It has no background monitoring, LAN device scan, speed test or Whois feature.
5. Third-party services and business model
This version has no ads or in-app purchases, includes no advertising, analytics, crash-reporting or social SDKs, and does not sell or send your data to third parties.
The app is distributed through Google Play. Depending on your device and Google Play settings, Google or the system may process distribution or diagnostic information, such as installations and crashes, under their own privacy policies, including the Google Privacy Policy (https://policies.google.com/privacy). This information is not uploaded by an in-app reporting SDK. Independent processing by the servers you check, your network provider and your DNS provider is outside this policy.
6. Children's privacy
The app is not directed at children under 13, creates no user accounts and does not actively collect personal information from any user.
7. Changes to this policy
We may update this policy when features or legal requirements change and will show a new effective date on this page. If a future version changes data handling, refer to the policy and actual features applicable to that version.
