Privacy Policy

Effective: April 2026 · Updated for advertising transparency · Client-side detection
Last updated: August 13, 2026

WhatPhone ("we", "our", or "the Service") is committed to protecting your privacy and providing transparent information about data practices. This Privacy Policy explains how WhatPhone handles information, including our client-side device detection and any third-party advertising services such as Google AdSense.

Key Principle: WhatPhone's core device detection runs entirely in your browser and does not transmit personal device data to our servers. However, if advertisements are displayed (including via Google AdSense), third-party vendors may use cookies and similar technologies as described below.

1. Information We Do Not Collect Directly

WhatPhone is primarily a client-side web application. When you use the device detection features:

  • No personal information (name, email, phone number) is requested or collected by WhatPhone.
  • No device identifiers or detection results from the "Detect My Phone" feature are sent to any WhatPhone server.
  • No first-party analytics scripts or tracking libraries controlled by WhatPhone are embedded for user profiling.

All core detection — User Agent parsing, screen resolution, battery status, network information, hardware capabilities, and feature detection — is performed using JavaScript APIs inside your browser. Results are displayed on your screen and are not transmitted by WhatPhone.

2. How Detection Works (Client-Side)

When you click "Detect My Phone", your browser executes JavaScript that reads publicly available browser APIs, including:

  • Navigator API — browser name, OS, language, user agent string.
  • Screen API — resolution, color depth, orientation.
  • Battery Status API — battery level and charging status (if supported).
  • Network Information API — connection type, downlink, RTT (if supported).
  • Hardware concurrency & Device Memory API — CPU cores and approximate RAM.
  • Feature detection — WebGL, WebGPU, Bluetooth, NFC, and other browser capabilities.

This information stays on your device for the detection feature. WhatPhone does not log or store these detection results.

3. Advertising and Google AdSense

WhatPhone may display advertisements served by Google AdSense and other third-party advertising partners to support the free service.

Third-party vendors, including Google, use cookies and similar technologies to serve ads based on a user's prior visits to this website or other websites on the Internet.

Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to this site and/or other sites on the Internet.

  • These cookies may collect information such as IP address, browser type, device information, pages visited, and approximate location (derived from IP).
  • This data is used for ad personalization, frequency capping, measurement, fraud prevention, and aggregated reporting.
  • Web beacons or similar technologies may also be used in connection with ad serving.

For more details on how Google uses data from sites that use its services, please see How Google uses information from sites or apps that use our services and Google's Privacy Policy.

Opting Out of Personalized Advertising

You may opt out of personalized advertising by visiting:

You can also manage cookies through your browser settings. Note that opting out of personalized ads does not mean you will no longer see ads; you may still see non-personalized advertisements.

4. Cookies and Similar Technologies

WhatPhone itself does not set first-party cookies for tracking or analytics. However:

  • Your browser may cache static assets (HTML, CSS, JS) for performance — this is standard browser behavior.
  • When ads are displayed, Google AdSense and other third-party ad networks may set and read cookies, local storage, or use similar technologies on your device.
  • These third-party cookies are governed by the respective vendors’ privacy policies.

For detailed information about cookies on this site, please also refer to our Cookie Policy (if available) or the disclosures in this Privacy Policy.

5. Hosting and Third-Party Infrastructure

WhatPhone is hosted on GitHub Pages, a service provided by GitHub, Inc. GitHub may collect standard web server logs (e.g., IP address, timestamp, requested URL, user agent) for security, performance, and operational purposes. These logs are governed by GitHub’s Privacy Statement. WhatPhone has no control over and does not access these infrastructure logs.

We do not integrate additional first-party analytics or advertising networks beyond those disclosed here. Any future changes will be reflected in an updated version of this policy.

6. Children's Privacy

WhatPhone is intended for general audiences and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information through third-party services on this site, please contact us so we can take appropriate action where possible.

7. Your Rights and Choices

Depending on your location, you may have rights under applicable privacy laws (such as GDPR, CCPA/CPRA, or others), including the right to access, correct, delete, or restrict certain processing of personal data, and to opt out of the sale or sharing of personal information for advertising purposes.

Because WhatPhone does not collect personal data itself through the detection tool, many of these rights apply primarily to data held by third parties (Google, GitHub, etc.). You can exercise opt-out rights for advertising as described in Section 3. For other requests, contact us using the information below.

8. International Users

If you are located in the European Economic Area, United Kingdom, or Switzerland, please note that Google’s services (including AdSense) are subject to Google’s EU User Consent Policy. We strive to provide appropriate disclosures and, where required by law, obtain consent for non-essential cookies and personalized advertising via consent mechanisms when implemented.

9. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in practices, technology, legal requirements, or the addition of advertising services. The "Last updated" date at the top indicates when changes were made. We encourage you to review this page periodically. Continued use of WhatPhone after changes constitutes acceptance of the updated policy.

10. Contact Us

If you have any questions about this Privacy Policy, our data practices, or advertising disclosures, you can reach us via the GitHub repository linked in the site footer or by email at meraalshah447@gmail.com.

Since core detection collects no personal data on our side, privacy inquiries are handled informationally. For issues related to Google AdSense or third-party cookies, please also consult the respective vendors’ privacy policies and opt-out tools.
