Privacy Policy — Real Speed Check

Overview

Real Speed Check is a network speed testing Chrome extension. This Privacy Policy explains what data we handle when you use the extension and how that data is used.

Short version: We do not sell your data, do not run ads, and do not collect personal information for tracking. Speed test requests are sent only to the test endpoint you use, and results can be stored locally on your device (optional).

Data We Process

When you run a speed test, the extension may process the following:

Network performance measurements such as latency (ping), jitter, download speed, upload speed, and timestamps.
Extension settings such as selected test endpoint, timeout, and data limits.
Optional test history (if you enable it), stored locally in your browser.

Data We Do Not Collect

No name, email, phone number, or account information.
No browsing history, page content, or keystrokes.
No precise location data.
No cross-site tracking identifiers.

Where Your Data Is Stored

By default, settings and (if enabled) test history are stored locally using Chrome’s extension storage on your device. We do not automatically sync this information to any developer-controlled server.

Network Requests (Speed Test Endpoint)

To measure your connection, the extension sends requests to a speed test endpoint. If you use the default endpoint, requests go to:

https://real-speed-check-api.lzx19901111.workers.dev

These requests may include standard HTTP metadata that any server receives, such as your IP address, user agent, and timing information necessary to deliver a response. This data is required to perform the speed test.

Third-Party Services

The default speed test endpoint is hosted on Cloudflare Workers. Cloudflare may process request metadata (e.g., IP address and basic logs) as part of providing network delivery and security. Cloudflare’s handling of this data is governed by Cloudflare’s own policies.

How We Use Data

To calculate and display speed test results (latency/jitter/download/upload).
To save your preferences and (optionally) your test history locally for your convenience.
To diagnose errors within the extension (shown to you locally).

Data Sharing

We do not sell, rent, or share your personal data. The only external communication is the speed test network request to the endpoint you choose.

Security

We aim to minimize data access and request scope. The extension uses the least permissions required to function and restricts network access to the test endpoint domain(s) you configure.

Your Choices

You can disable test history storage in the extension settings.
You can clear locally stored settings and history from the extension options page (if provided) or Chrome’s extension storage.
You can change the speed test endpoint to a self-hosted endpoint of your choice.

Children’s Privacy

Real Speed Check is not directed to children under 13 and does not knowingly collect personal information from children.

Changes to This Policy

We may update this Privacy Policy from time to time. The “Last updated” date below will reflect the latest version.
