Privacy Policy

Last updated: October 12, 2026

This policy explains what information is processed when you use NetHealthLab at nethealthlab.com (the “Service”), why, and the choices you have. It describes what the Service actually does today. If our practices change, for example if we introduce advertising, we will update this policy before the change takes effect.

1. Who we are

NetHealthLab is operated by Smart Trans Logistic LLC, based in California, United States (“we”, “us”, “our”). You can contact us about this policy or your information at info@nethealthlab.com.

2. Information we process

Network and request information

When your browser connects to the Service, your IP address and standard request details (such as the time of the request, the page or resource requested, and your browser’s user-agent string, which identifies the browser and operating system) are processed to deliver the Service and protect it from abuse. This processing is carried out by our hosting and network provider, Cloudflare. Our own server code doesn’t log or store this information, and we have turned off logging and tracing for that code. Cloudflare may keep limited records and produce aggregate statistics, such as total request counts, under its own policies.

Browser and device information

The check runs in your browser and uses your device’s built-in capabilities, such as precise timing, to calculate results. Those results stay in your browser.

Generated measurement traffic

To measure speed, the Service sends and receives test data. Download data is random filler text generated by our server; upload data is blank filler generated by your browser. It doesn’t contain your files or personal content.

Information you send us

If you email us, we receive your email address, any name you include, the content of your message and any attachments, along with standard email headers.

What we don’t collect

We don’t ask for or collect names, accounts, passwords, payment details, precise (GPS) location, contacts or files from your device.

3. Internet test data

• What is generated: small timing requests and larger download and upload transfers of filler data. How it works describes each step.
• Where it flows: between your device and NetHealthLab’s server code, which runs on Cloudflare’s network, usually in a data centre near you.
• What is calculated on your device: download and upload speed, latency, jitter, latency under load, the Internet Health Score, the rating, the finding and the suggestion.
• What we keep: nothing from your check. Results aren’t sent to us or stored on our servers, and they disappear when you close or reload the page. Our server code reads test data only to receive it and discards it immediately.
• What our provider may keep: as described in section 2, Cloudflare processes connection details for every request, including test requests, under its own policies.

The check uses an open-source measurement library published by Cloudflare. It runs in your browser, and we have switched off its option to report results to Cloudflare.

4. How we use information

• to run the check and show you the website;
• to keep the Service secure and reliable, and to prevent abuse such as automated overuse of the test servers;
• to reply to messages and handle privacy requests;
• to understand overall use and performance of the Service through aggregate statistics, including from Cloudflare Web Analytics (see section 6);
• to comply with the law and protect our rights.

We don’t use information to build profiles of you or to target advertising.

5. Service providers

We use a small number of companies to run the Service. They process information on our behalf to provide their services to us:

• Cloudflare, Inc. hosts the website and test servers, delivers them over its global network, protects them from attacks, provides our website analytics (Cloudflare Web Analytics), and routes email sent to our address. Cloudflare’s privacy policy.
• Google LLC provides the mailbox where messages sent to info@nethealthlab.com are delivered. Google’s privacy policy.

We may also disclose information if required by law, to protect the safety or rights of users or others, or as part of a merger, acquisition or sale of the business, in which case this policy would continue to apply to it.

6. Cookies and similar technologies

The NetHealthLab website doesn’t currently set cookies, and our code doesn’t use your browser’s local storage or session storage. We don’t use advertising cookies, tracking pixels or social media plugins, and we don’t use Google Analytics.

Cloudflare Web Analytics

We use Cloudflare Web Analytics to understand aggregate site usage and performance: for example, how many pages are viewed, which pages and referring websites visitors come from, the general type of browser and device, the approximate country, and how quickly pages load. A small script provided by Cloudflare runs on our pages and sends this information to Cloudflare through our own domain. Cloudflare states that Web Analytics doesn’t use cookies or local storage for analytics and doesn’t track individual users over time by their IP address or browser details. This analytics setup sets no advertising cookies. Cloudflare doesn’t load the analytics script for visitors in the European Union.

Analytics doesn’t record your check results. No account is required, and we still don’t store your measurements.

Our network provider may use strictly necessary security measures. For example, if it detects unusual traffic, it may show a security check that sets a cookie to remember that you passed it.

This may change if we introduce advertising. We’ll update this section before that happens.

7. Advertising

NetHealthLab doesn’t show ads today. We may introduce advertising in the future, for example through Google AdSense, to keep the Service free. Advertising partners typically use cookies, device identifiers and similar technologies to show ads, limit how often you see them, measure their performance and, where permitted, personalise them. In doing so they may receive information such as your IP address and browser details.

Before any advertising launches, we will update this policy to describe it, provide the choices required by law (including the controls on Your Privacy Choices), and ask for consent where the law requires it. Advertising will never be part of the check itself and won’t affect your score.

8. California privacy rights

The California Consumer Privacy Act, as amended by the California Privacy Rights Act (together, the “CCPA”), gives California residents rights over their personal information. The CCPA applies to businesses that meet certain thresholds, such as annual gross revenue above an inflation-adjusted amount (currently over US$25 million), or buying, selling or sharing the personal information of 100,000 or more California consumers or households a year. Whether or not these thresholds apply to us, we will honour the requests below for any personal information we hold about you.

Right to know and access

You can ask what personal information we have collected about you, where it came from, why we use it, who we disclose it to, and for a copy of it.

Right to delete

You can ask us to delete personal information we hold about you, subject to legal exceptions.

Right to correct

You can ask us to correct inaccurate personal information we hold about you.

Right to opt out of sale or sharing

We don’t sell or share personal information (see section 9). If that ever changes, you’ll be able to opt out on Your Privacy Choices.

Right to limit use of sensitive personal information

We don’t collect or use sensitive personal information for any purpose that gives rise to this right.

Right to non-discrimination

We won’t deny you the Service, charge you differently or give you a different quality of service for exercising your rights.

How to make a request

Email info@nethealthlab.com with “Privacy request” in the subject line and tell us what you’d like us to do. Because we don’t have accounts and don’t keep records of individual checks, we often won’t hold any information that we can link to you. If the only information we hold is an email you sent us, we’ll verify your request by replying to that address. You can use an authorised agent; we may ask for proof of their authority and for you to confirm your identity with us directly.

Where the CCPA applies, we will confirm receipt within 10 business days and respond within 45 calendar days, and we will tell you if we need more time, as the law allows.

Categories of personal information (last 12 months)

Identifiers

IP address, processed by our network provider for every request; your email address if you contact us. Source: you and your browser. Purpose: providing and securing the Service, and replying to you. Disclosed to: service providers (Cloudflare; Google for email). Sold or shared: no.

Internet or other electronic network activity

Request details such as the resource requested, the time and your browser’s user-agent string, and website analytics such as pages viewed, referring websites and page load performance. Source: your browser. Purpose: providing, securing and understanding use of the Service. Disclosed to: Cloudflare. Sold or shared: no.

Approximate location

A general area such as the country, which our network provider can infer from your IP address for routing, security and aggregate statistics, including website analytics. We don’t use it to identify you. Disclosed to: Cloudflare. Sold or shared: no.

Communications

The content of emails you send us. Source: you. Purpose: replying and keeping records. Disclosed to: Cloudflare and Google as email providers. Sold or shared: no.

Sensitive personal information

None collected intentionally. Please don’t include sensitive information in emails to us.

Other California disclosures

Shine the Light. We don’t disclose personal information to third parties for their own direct marketing purposes.

Do Not Track. Some browsers can send a “Do Not Track” signal. There is no common standard for responding to it, so we don’t act on it specifically. We don’t track visitors across other websites, and we don’t currently allow third parties to collect information about your online activities over time and across websites through the Service. If that changes with advertising, we will say so here. We handle Global Privacy Control signals as described in section 10.

9. Sale and sharing of personal information

California law gives “sale” and “sharing” specific meanings. A sale is disclosing personal information to a third party for money or other valuable consideration. Sharing is disclosing personal information to a third party for cross-context behavioural advertising, meaning ads targeted using your activity on other websites or services.

We don’t sell or share personal information, and we haven’t done so in the past 12 months. We have no actual knowledge of selling or sharing the personal information of anyone under 16.

Some advertising arrangements can count as “sharing” under California law. If we introduce one, we will update this policy and provide a “Do Not Sell or Share My Personal Information” control on Your Privacy Choices before it takes effect.

10. Global Privacy Control

Global Privacy Control (GPC) is a setting in some browsers and extensions that tells websites you want to opt out of the sale and sharing of your personal information. Because we don’t sell or share personal information today, there’s currently nothing for the signal to switch off. If we introduce any practice that California law treats as a sale or sharing, we will treat a valid GPC signal as a request to opt out for that browser, without asking you to do anything else, as the law requires. Your Privacy Choices shows whether your browser is sending the signal.

11. Data retention

• Check results: not stored by us.
• Request details processed by Cloudflare: our own code doesn’t store them; Cloudflare retains information according to its own policies.
• Emails: kept for as long as needed to deal with your message and keep a reasonable record of it, and then deleted.
• Privacy requests: a record of the request and our response is kept for at least 24 months, where the law requires it.

12. Children’s privacy

The Service isn’t directed to children under 13, and we don’t knowingly collect personal information from them. If you believe a child has sent us personal information, for example by email, contact us and we will delete it.

13. Security

All connections to the Service use encrypted HTTPS. We keep the information we handle to a minimum, have disabled logging in our own server code, and limit access to our email and provider accounts. No method of transmission or storage is completely secure, but we take reasonable steps to protect information.

14. International visitors

The Service is operated from the United States. Cloudflare usually handles your connection in a data centre near you, which may be outside your country, and email is processed by our providers in the United States and elsewhere. If you live in a region with its own data-protection laws, such as the European Union or the United Kingdom, you may have rights under those laws. Contact us and we will respond in line with the law that applies to you.

15. Changes to this policy

We’ll update the date at the top of this page whenever we change this policy. For significant changes, including the introduction of advertising, we’ll update the policy before the change takes effect and highlight it on the site.
