Your data stays
on your device.
Network Meter is built with a simple principle: measure your network speed locally, store nothing remotely, and never share anything about you with anyone.
No personal data collected
We do not collect your name, email, IP address, location, or any identifying information.
Everything stored locally
All speed readings, settings, and usage data are stored only on your device using Chrome's local storage.
No third-party sharing
We do not sell, share, or transfer any data to advertisers, analytics services, or any third party.
No page content read
The extension only reads response byte sizes — never page content, URLs, form data, or browsing history.
1. Introduction
This Privacy Policy describes how Network Meter ("the Extension"), developed by AZHAR (publisher: AZ&G), handles information when you install and use the extension in Google Chrome or Microsoft Edge.
Network Meter's sole purpose is to measure and display your real-time internet download and upload speed in the browser toolbar. It tracks daily data usage locally and allows you to run manual or automatic speed tests against Cloudflare's public speed infrastructure.
By installing or using the Extension, you agree to this Privacy Policy. If you do not agree, please uninstall the Extension.
2. What Data Is Collected
Network Meter collects no personal data. The following table summarises every category of information and how it is handled:
| Data Type | Collected? | Details |
|---|---|---|
| Personal identity | Never | Name, email, age, address — none of this is accessed or stored. |
| Browsing history | Never | URLs, page titles, or visited sites are never read or recorded. |
| Page content | Never | The extension reads only the Content-Length header to count bytes. No page text, images, or form data is accessed. |
| Speed readings | Local only | Download/upload Bps values are stored in chrome.storage.local on your device. They never leave your browser. |
| Daily usage totals | Local only | Byte counts for the current day are stored locally and reset each day. Never transmitted. |
| User preferences | Local only | Settings such as test duration and auto-interval are stored locally using chrome.storage.local. |
| IP address / location | Never | The extension does not access, log, or transmit your IP address or geographic location. |
| Authentication data | Never | Passwords, credentials, tokens — never accessed. |
3. Permissions Explained
The Extension requests the following browser permissions. Each permission is used strictly for the extension's core functionality and nothing else.
-
storage
Stores speed readings, daily usage totals, and user settings locally on your device using
chrome.storage.local. No data is synced to the cloud or transmitted anywhere. -
webRequest
Reads only the
Content-Lengthresponse header and upload request body sizes to calculate real-time download and upload byte rates. No request URLs, content, or user data are accessed or stored. - alarms Schedules the periodic auto-speed-test timer at your configured interval (default: every 10 seconds). Used only to keep the toolbar badge updated in the background.
- offscreen Creates an offscreen document to run the background auto-sampling scheduler, allowing speed tests to continue when the popup is closed. No user data is processed in this document.
-
<all_urls>
Required by
webRequestto intercept network response headers across all websites in order to measure download and upload speeds. The extension reads only byte-size metadata — never content, text, or URL paths.
4. Third-Party Services
Network Meter performs speed tests using Cloudflare's public speed measurement endpoints:
speed.cloudflare.com/__up — used to upload randomly generated bytes.
These requests are made solely to measure network throughput. The payloads sent during upload tests are randomly generated binary data — they contain no personal information, no browsing data, and no identifiers.
Cloudflare's own privacy policy governs their handling of these requests. You can review it at cloudflare.com/privacypolicy.
The Extension does not use any analytics services, advertising networks, crash reporting tools, or any other third-party SDKs.
5. Data Storage & Retention
All data produced by the Extension is stored exclusively in
chrome.storage.local — a browser-managed,
device-local storage area that is never synchronized to any server or cloud account.
The following data is retained locally:
- Last 60 speed samples (ring buffer) — overwritten continuously
- Today's download and upload byte totals — reset each calendar day
- Last manual speed test result (Mbps values and timestamp)
- User settings (test duration, auto interval, payload size, enabled state)
All locally stored data is permanently deleted when you uninstall the Extension. You can also clear it manually at any time from the Extension's Settings page using Chrome's "Clear data" option.
6. Children's Privacy
Network Meter does not knowingly collect any information from anyone, including children under the age of 13. The Extension collects no personal data from any user of any age.
7. Changes to This Policy
If this Privacy Policy is updated, the revised version will be published at this URL and the "Last updated" date at the top of this page will be changed accordingly.
Continued use of the Extension after any changes constitutes your acceptance of the updated policy. Significant changes will also be noted in the Extension's Chrome Web Store changelog.
