Privacy Policy

Effective: March 2026 · No data collection · 100% client-side
Last updated: April 2, 2026

WhatPhone ("we", "our", or "the service") is committed to protecting your privacy. This Privacy Policy explains that we do not collect, store, or share any personal data. All device detection occurs locally within your web browser.

1. No Data Collection

WhatPhone is a fully client-side web application. When you visit WhatPhone:

  • No personal information (name, email, IP address, location) is collected.
  • No device identifiers are sent to any server.
  • No cookies are used for tracking or analytics (see Cookie Policy for essential exceptions).
  • No analytics scripts, third-party trackers, or fingerprinting libraries are embedded.

All detection — including User Agent parsing, screen resolution checks, battery status, network information, and hardware capabilities — is performed using JavaScript APIs inside your browser. Results are displayed on your screen and never transmitted over the network.

2. How Detection Works (Client-Side)

When you click "Detect My Phone", your browser executes JavaScript that reads:

  • Navigator API — browser name, OS, language, user agent.
  • Screen API — resolution, color depth, orientation.
  • Battery API — battery level and charging status (if supported).
  • Network Information API — connection type, downlink speed, RTT.
  • Hardware concurrency — CPU cores, memory (device memory API).
  • Feature detection — WebGL, WebGPU, Bluetooth, NFC, etc.

All this information stays exclusively on your device. No data leaves your browser. We do not log or store any request details. Your privacy is absolute.

3. No Third-Party Services

WhatPhone does not integrate with any external analytics, advertising networks, CDNs that log requests (the site is served via static GitHub Pages, which may retain standard server logs as per GitHub's Privacy Statement). However, WhatPhone itself does not initiate any tracking or data transmission beyond loading the HTML, CSS, and JavaScript files.

GitHub Pages may collect standard web server logs (e.g., IP address, timestamp, requested URL) for security and performance monitoring. These logs are governed by GitHub’s privacy policy. WhatPhone has no control over GitHub’s infrastructure logs and does not access or process them.

4. Local Storage & Cookies

WhatPhone does not use cookies for tracking, personalization, or analytics. We do not store any data in localStorage, sessionStorage, or IndexedDB. The only exception is that your browser may cache the website assets (CSS, JS) for performance — this is standard browser behavior and not controlled by WhatPhone. For detailed cookie information, please see our Cookie Policy.

5. Children's Privacy

WhatPhone is intended for general audiences and does not knowingly collect any information from children under 13. Since no data collection occurs, no special restrictions apply. Parents and guardians can rest assured that no personal information is ever requested or stored.

6. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in practices or for legal reasons. The "Last updated" date at the top indicates when changes were made. We encourage you to review this page periodically. Continued use of WhatPhone constitutes acceptance of any updated terms.
