GaugeCalc App Privacy Policy

Android app, last updated: November 2026

This policy covers the GaugeCalc: CCTV & Network Android app (package com.gaugecalc.app). The website gaugecalc.com has its own privacy policy.

Summary

The app has no account, no sign-in, no advertising, no analytics and no crash-reporting service. We do not run a server for the app and we do not collect, receive or sell your data.

What is stored on your phone

Your favourites, recent items, calculation history, language, theme, chosen fields and screen-ruler calibration are stored only in the app's private storage on your phone. You can clear the history inside the app, and uninstalling the app removes everything. This data never leaves your phone.

When the app uses the internet

The calculators, guides and most tools work offline. The app asks for the Android INTERNET permission for one tool only, Network Tests, and only when you start a test:

  • TCP ping, port test, device discovery and ONVIF check connect to the address you type, or to devices on your own local network.
  • “Look up public address” sends one request to api.ipify.org when you tap it.
  • DNS lookup contacts the public DNS servers 1.1.1.1 (Cloudflare) and 8.8.8.8 (Google) with the name you enter.
  • WHOIS contacts whois.iana.org and the registry it names, with the name or address you enter.

These requests go straight from your phone to those services. The app does not keep the results after you leave the tool, and we never see them. Those services have their own privacy policies.

Permissions

The app does not ask for camera, microphone, location, contacts, storage or phone permissions.

Sharing and support

When you tap Share or export a PDF, the report is handed to the share sheet or the system print service that you choose. “Contact support” opens your own mail app with a message you can edit; it contains only what you type and the app version.

Children

The app is made for working technicians and is not directed at children. It collects no personal data from anyone.

Changes to this policy

If the app's use of data changes, this page will be updated with a new date before the new version is released.
