Privacy Policy for Public Wi-Fi Phishing Alert

Last updated: October 2026

1. Overview

Public Wi-Fi Phishing Alert is an open-source browser extension designed to detect network-level captive portal redirects and display visual warnings on untrusted public Wi-Fi networks.

2. Data Collection and Storage

We do not collect, store, track, or transmit any personal data.

• No Analytics or Telemetry: The extension contains zero tracking scripts, third-party analytics, or logging frameworks.
• No Personal Information: We do not capture or inspect credentials, browsing history, form inputs, or IP addresses.
• Local Session State: Transient identifiers (tab IDs) are stored in local browser memory (chrome.storage.session) strictly to track active warning overlays across navigations. This data never leaves your device and is destroyed when the browser is closed.

3. Extension Permissions

Broad Host Permission Disclosure (<all_urls>)

This extension requests access to <all_urls> solely because captive portal login pages operate on arbitrary, unpredictable domain names (e.g., 192.168.1.1, login.hotelwifi.com). This permission is strictly utilized to inject local warning CSS/JS stylesheets into flagged portal tabs and never to inspect or extract web contents.

Other Permissions

The extension requests specific permissions solely to perform local network checks and render warning interface elements:

• webNavigation: Monitored to detect initial network probe requests (e.g., generate_204) and track child tab navigations from flagged portals.
• scripting & <all_urls>: Required to inject the visual hazard frame and top warning banner into intercepted portal pages regardless of their domain.
• storage: Used to temporarily store active tab state locally in browser session memory.

4. Network Requests

To evaluate network connectivity, the extension performs a stateless HTTP GET request to a standard endpoint (http://connectivitycheck.gstatic.com/generate_204). This request carries no personal identifiers, user credentials, or tracking cookies.

5. Changes to This Policy

If updates are made to the extension that impact user privacy, this document will be updated accordingly in the repository.
