Privacy Policy

Effective Date: June 2, 2026 Last Updated: June 2, 2026

This Privacy Policy explains how mobilutils ("we," "us," or "our") collects, uses, processes, and protects information in relation to the NTP DIG PING MORE mobile application (the "App" or "Application") for Android, distributed via Google Play.

We take your privacy very seriously. This App is designed as a client-side-only Network Diagnostics Toolbox — it does not operate a proprietary backend database, cloud server, or remote service to collect your personal information. All data processing occurs locally on your device.

This Privacy Policy complies with:

• The General Data Protection Regulation (GDPR) (Regulation (EU) 2016/679)
• The California Consumer Privacy Act (CCPA) / California Privacy Rights Act (CPRA)
• The Children's Online Privacy Protection Act (COPPA) (15 U.S.C. § 6501 et seq.)
• Google Play Developer Program Policies, including the Data Safety section requirements
• Android Permission disclosure requirements

Please read this Privacy Policy carefully to understand our practices regarding your information. By installing and using the App, you agree to the collection and use of information in accordance with this policy.

1. Introduction

NTP DIG PING MORE is a comprehensive, client-side Network Diagnostics and Troubleshooting Toolbox developed by mobilutils. It enables users to perform local network analysis, including:

• NTP (Network Time Protocol) Checks — Query NTP servers for time synchronization
• DIG (DNS) Lookups — Resolve domain names using DNS servers
• ICMP Ping — Test host reachability
• Traceroute — Trace network packet paths
• TCP/UDP Port Scanning — Identify open ports on target hosts
• LAN Scanner — Discover devices on your local subnet
• Google Time Sync — Synchronize with Google's time servers
• HTTPS Certificate Inspector — Examine TLS certificate details
• Device Info — Display device identity, network state, and hardware details
• Bulk Actions — Execute batch diagnostic commands from JSON configurations

The App is built to operate exclusively on your device. It does not send your data to any of our servers or third-party analytics platforms. All diagnostic results are processed in real-time and displayed locally.

2. Information We Collect

To provide robust network diagnostic services, the App requires access to certain device capabilities and processes specific network/device information. Below is a comprehensive disclosure of all data types collected, processed, and stored.

A. Network and Diagnostic Data (Processed On-Device Only)

When you run diagnostic tests, the following parameters are processed locally within the App:

Important: All of the above data is processed entirely on your device. We do not collect, transmit, store, or access any of this diagnostic data on our servers.

B. Sensitive Android Permissions

Under Google Play's Developer Program Policies and Android's permission model, we explicitly disclose the use of sensitive permissions and resources. The App requests the following permissions strictly for core diagnostic utility:

1. android.permission.INTERNET

• Category: Normal Permission (auto-granted at install)
• Purpose: Allows the App to open network sockets. This is essential for executing ICMP pings, NTP UDP packet exchanges (port 123), DNS lookups (port 53), TCP port scans, HTTP(S) requests (including Google Time Sync), and TLS certificate handshakes.

2. android.permission.ACCESS_NETWORK_STATE

• Category: Normal Permission (auto-granted at install)
• Purpose: Allows the App to verify whether the device has an active network connection (and the type — Wi-Fi, Cellular, Ethernet, VPN) before initiating diagnostic tools. Used to prevent failed requests when no internet is available.

3. android.permission.ACCESS_WIFI_STATE

• Category: Normal Permission (auto-granted at install)
• Purpose: Allows the App to access technical details of your current Wi-Fi connection, such as Wi-Fi signal strength (RSSI), frequency band (2.4 GHz / 5 GHz), connection speed (Mbps), and SSID/BSSID. Required for the Device Info screen's network diagnostics section.

4. android.permission.ACCESS_COARSE_LOCATION & android.permission.ACCESS_FINE_LOCATION

• Category: Dangerous Permissions (require runtime request, Android 10+)
• Critical Policy Disclosure: On modern Android operating systems (API 29+), access to a network's name (SSID) and access point identifier (BSSID) is legally classified as data that could reveal your location. Therefore, Android requires location permissions to retrieve the Wi-Fi SSID and BSSID for display purposes.
• Our Practice: We do not track, collect, store, or transmit your geographical coordinates (GPS location). These permissions are requested solely to retrieve the Wi-Fi SSID and BSSID for local network diagnostics and LAN subnet scans. You may refuse or revoke this permission at any time in system settings; doing so will limit the App's ability to display the network SSID/BSSID but will not prevent other diagnostic tools from running.
• Data Processed: Wi-Fi SSID (network name), BSSID (MAC address of access point). No GPS coordinates are accessed.

5. android.permission.READ_PHONE_STATE

• Category: Dangerous Permission (requires runtime request)
• Purpose: Used strictly to read cellular carrier and network type details (e.g., SIM operator name, network class — LTE/5G/CDMA) to display detailed mobile network diagnostics on the Device Info screen. On Android 10+ (API 29+), this permission no longer grants access to IMEI or serial numbers for third-party apps.
• Our Practice: We do not collect, store, or transmit your phone number, IMEI, MEID, or hardware serial number. Any device identifiers that may be accessible are displayed locally on-screen only and are not persisted or transmitted externally.

6. android.permission.WRITE_EXTERNAL_STORAGE & android.permission.READ_EXTERNAL_STORAGE

• Category: Dangerous Permission (up to maxSdkVersion="32" / Android 12)
• Purpose: Used exclusively to allow you to export local network scan reports, diagnostic logs, or Bulk Actions results to your device's shared storage at your explicit request. Not used for any other purpose.
• Note: On Android 13+ (API 33+), READ_EXTERNAL_STORAGE is no longer grantable; the App uses the Storage Access Framework (SAF) for file operations instead.

C. Local Data Storage (On-Device Only)

The App stores a limited amount of data locally on your device using Android's Preferences DataStore (sandboxed, private app storage). This data is never transmitted to us or any third party:

Storage Format Details:

• Query history entries are stored as pipe-delimited strings (e.g., timestamp|server|port|success) or JSON objects (for LAN Scanner) within DataStore preference keys.
• No personal identifiers, device serial numbers, or network scan results beyond the last 5–10 queries are retained.

3. How We Use the Information

The information processed by the App is used solely for the following purposes:

• To Provide Diagnostic Functionality: Executing network utility requests (e.g., resolving a domain name via DNS, testing port availability via TCP handshake, measuring packet loss and latency via ICMP)
• To Display Local Results: Showing real-time terminal output, latency logs, device details, certificate information, and scan results directly to you inside the App UI
• On-Device History Preservation: Saving a local history of your most recent queries (last 5–10 entries per tool) for quick access. This history is stored strictly in your device's local secure Preferences DataStore and is never sent to us
• To Improve App Stability & User Experience: Identifying and troubleshooting crashes, performance bottlenecks, and UI issues using local debug logs generated during your use of the App

4. Third-Party Sharing & SDKs

A. General Sharing Policy

We do not sell, trade, rent, share, or otherwise disclose any of your personal information or network diagnostic data to any third parties.

Because the App operates strictly on-device, no third parties receive your diagnostic inputs, query history, or local network scan results. Any communication with external servers is initiated solely by you to carry out tests you actively request (e.g., querying your chosen DNS server, pinging a target host, synchronizing time with an NTP pool).

B. Third-Party Service Providers & SDKs

This App integrates no third-party advertising, tracking, analytics, or crash-reporting SDKs.

The App is completely self-contained and offline. It does not use Google Firebase (Crashlytics/Analytics), Google AdMob, Facebook SDK, or any other third-party tracking/analytics library.

The only external network communication initiated by the App — when you choose to use it — involves:

Google Time Sync Service (clients2.google.com)

• Data Transmitted: A standard HTTP GET request is sent to http://clients2.google.com/time/1/current (or its XSSI-prefixed variant) when running the Google Time Sync diagnostic test. This transmits only a public HTTP request containing your device's IP address as part of the standard TCP/IP protocol handshake — no identifying personal user data, device identifiers, or query content is included in the request body or headers beyond what a standard HTTP request inherently contains.
• Purpose: Strictly to retrieve public Google Time server timestamps to calculate round-trip delay and compute precise on-device clock offset.
• Privacy Link: Google Privacy & Terms (opens in a new tab)
• Your Control: You may skip this feature entirely or use a different NTP server pool (e.g., pool.ntp.org) instead.

Your Chosen Third-Party Servers (User-Selected Targets)

When you enter a hostname or IP address to ping, resolve, or scan, the App sends network packets directly to the target you specified. This includes:

• DNS queries sent to your chosen DNS resolver (e.g., 8.8.8.8, 1.1.1.1, or a custom server)
• ICMP ping packets sent to the target host
• TCP connection attempts to specified ports on target hosts
• NTP UDP packets sent to the NTP pool server you selected
• TLS certificate requests to the HTTPS host you inspected

Important: These communications occur between your device and the third-party servers you specify. We do not intercept, log, store, or have access to this data. Please review the privacy policies of any third-party services you choose to query.

C. Proxy PAC (Optional Feature)

The App includes an optional Proxy PAC (Proxy Auto-Configuration) feature. If you enable a PAC script URL in Settings:

• The PAC script URL is fetched from the server you specify (e.g., http://proxy.corp.com/proxy.pac)
• The PAC script is evaluated locally on your device using the QuickJS JavaScript engine
• Network traffic for specified tools may be routed through the proxy determined by the PAC script
• We do not collect, log, or access any data passing through your configured proxy

5. Data Retention and Security

Data Retention

• Local Diagnostic History: All network scan logs, diagnostic query history, and target inputs are stored exclusively in your device's local DataStore sandbox. They remain on your device until you:
  • Clear the App's data in Android Settings (Settings → Apps → NTP DIG PING MORE → Storage → Clear Data)
  • Uninstall the App
  • Manually delete query history entries within the App UI (where available)
• Settings & Configuration: Your configured settings (timeout values, proxy URLs, PAC toggles) are retained locally on your device until you reset them or uninstall the App.
• No Server Storage: We do not host, operate, or maintain backend servers that store your queries, diagnostic histories, or any network data.

Data Security

We implement industry-standard security measures to protect data stored on your device:

• Android Sandbox: The App uses Android's built-in sandboxed storage mechanism, which prevents other apps from accessing NTP DIG PING MORE's internal data files and Preferences DataStore
• No Network Transmission of Local Data: All locally stored data (query history, settings) is never transmitted over the network — it remains in your device's private app directory (/data/user/0/io.github.mobilutils.ntp_dig_ping_more/)
• Secure Defaults: Sensitive permissions (location, phone state) are requested at runtime only when needed, and you retain full control to deny or revoke them at any time
• No Plaintext Storage of Credentials: The App does not store passwords, API keys, or authentication tokens

Please note: While we implement reasonable security measures, no method of transmission over the internet or method of electronic storage is 100% secure. We cannot guarantee absolute security of data stored on your device, especially if your device is rooted, compromised, or accessed by unauthorized parties.

6. Children's Privacy

The App is not directed at children under the age of 13 and does not knowingly collect, store, or solicit personal information from children under 13 (or the applicable minimum age in your jurisdiction). We strictly comply with:
