Privacy Policy

Effective Date: August 26, 2026

Subnetix - IP Calculator ("we", "us", "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our Subnetix - IP Calculator mobile application (the "App"), a tool designed to calculate IPv4 and IPv6 subnet parameters, plan subnets, and practice subnetting skills.

Information We Collect

We prioritize minimal data collection.

Local-First Architecture: The App stores your data — such as saved calculations, calculation names, quiz progress, and settings — locally on your device. This data is never transmitted to our servers.No Account Required: The App does not require registration or an account. We do not collect email addresses, names, or personal identifiers.No Network Access: The App does not require an internet connection to perform any of its functions. It does not scan, probe, ping, or connect to any network, and it does not read your device's network configuration. All addresses and prefixes are entered manually by you.No Location Access: The App does not request or use your device location.Local Computation: All subnet calculations, subnet plans, reference content, and quiz questions are produced entirely on your device by arithmetic performed in the App itself. No address, prefix, or result is ever sent to us or to any third party by the App.Clipboard: If you choose to copy a result, the App writes text to the system clipboard through the operating system. The App does not read the contents of your clipboard.Sharing: If you use the share sheet, the content is handed to the destination you select. We do not receive or process it.No Analytics: The App contains no analytics, advertising, or tracking SDKs. We do not collect usage statistics, device identifiers, or behavioural data. If you have enabled sharing of diagnostics with developers in your iOS settings, Apple may provide us with anonymized crash reports; this is controlled entirely by you in the system settings and cannot be used to identify you.
