WA Number Checker Privacy Policy

Effective date: July 13, 2026

This policy explains how the WA Number Checker Chrome extension processes phone lists, imported Excel files, check results, local logs and local history.

1. Extension Purpose

WA Number Checker helps users check whether phone numbers in a list are available on WhatsApp Web and export the results.

2. Data Processed by the Extension

The extension may process phone numbers entered by the user, Excel files selected by the user, check results, WhatsApp display names when available, user interface language preferences, local logs, current progress and local check history.

3. How Data Is Used

The data is used only to provide the extension's core features: checking numbers in WhatsApp Web, showing progress and logs, exporting results, copying numbers when the user clicks the copy button, and exporting a previous local check from history.

4. Data Storage

The extension stores settings, progress, logs and check history in Chrome local extension storage on the user's device. The extension does not upload phone lists, Excel files, check history or exported results to the developer's server.

5. Data Sharing

The extension does not sell user data. The extension does not share user data with third parties for advertising, analytics, credit checks, data brokerage or unrelated purposes. The extension works on https://web.whatsapp.com/ because that page is required for the checking workflow.

6. Permissions

7. Remote Code

The extension does not load remote executable code. All JavaScript used by the extension is packaged with the extension.

8. User Control

Users can clear local check history in the extension. Users can also remove locally stored extension data by uninstalling the extension or clearing the extension's site/storage data in Chrome.

9. Affiliation

WA Number Checker is not affiliated with, endorsed by, sponsored by, or officially connected with WhatsApp LLC, Meta Platforms, Inc., or any of their subsidiaries or affiliates. WhatsApp is a trademark of its respective owner.

10. Contact

Users can contact the developer through the support contact listed on the Chrome Web Store listing for this extension.
