Cookie Policy

1. What Are Cookies?

Cookies are small text files that are placed on your device (computer, tablet, or smartphone) when you browse websites. They are widely utilized to make web applications operate efficiently, preserve your user preferences across visits, and deliver relevant information and advertisements to visitors.

2. How NetSpeedPro Uses Cookies & Local Storage

NetSpeedPro operates an advanced internet speed diagnostic engine. We employ cookies and browser LocalStorage for several clear, functional purposes:

• Essential Operational Cookies: Required for the basic functioning of the website, session tracking, CSRF security verification, and language selection.
• Preferences & User Experience: Storing your preferred visual theme (Dark Mode / Light Mode) and preferred speed units.
• Device Speed Test History: We generate a pseudonymous identifier stored in your browser's LocalStorage (speedtest_device_id). This allows you to review your past speed test comparisons on the History page without requiring you to create an account or provide personal email addresses.
• Diagnostic Telemetry: Storing temporary measurement timestamps during active download, upload, ping, and bufferbloat loaded latency probes.

3. Google AdSense & Third-Party Advertising Cookies

We partner with Google AdSense (Publisher ID: ca-pub-5525818152882852) to display relevant advertisements to help support our free network diagnostic services.

• Google uses cookies, including the DoubleClick cookie, to serve ads based on your prior visits to our website or other sites on the Internet.
• You may opt out of personalized advertising by visiting Google's Ads Settings.
• Alternatively, you can opt out of third-party vendor use of cookies for personalized advertising by visiting www.aboutads.info.
• When you choose "Essential Only" in our cookie consent banner, our code explicitly signals Google AdSense to serve non-personalized ads (requestNonPersonalizedAds = 1).

4. Managing & Disabling Cookies

You have complete control over cookies on your computer or mobile device. You can configure your browser settings to:

• Block all cookies entirely.
• Delete existing cookies and cached site storage.
• Receive an alert whenever a website attempts to set a cookie.

Please note that if you choose to disable essential cookies or LocalStorage, some website features—such as historical test logs and theme memory—may not function as intended.
