03 Cookies & Tracking Technologies

Cookies are small text files stored on your device when you visit a website. VoltageChecker.website uses the following categories of cookies:

Essential Cookies

These cookies are strictly necessary for the website to function. They do not store any personally identifiable information and cannot be disabled without affecting core site functionality.

Analytics Cookies

We may use anonymised analytics to understand how visitors use our site. All analytics data is aggregated and cannot be used to identify individual users. This helps us understand which features are most valuable and improve the overall experience.

Google AdSense and Adsterra place advertising cookies on your device to deliver ads that are relevant to your interests, based on your browsing behaviour. See Section 4 for full details on how this works and how to opt out.

04 Advertising — Google AdSense & Adsterra

VoltageChecker.website uses two advertising networks — Google AdSense and Adsterra — to display ads across the site. Advertising revenue is what allows us to keep this tool completely free for everyone, with no subscription, no registration, and no paywalls.

Google AdSense

Google AdSense is an advertising service provided by Google LLC. It uses cookies and web beacons to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and/or other sites on the Internet.

What Google May Collect

• Your IP address (used to infer general location)
• Browser type, version, and device identifiers
• Cookie data associated with your Google account (if you are logged in)
• Browsing behaviour across websites that participate in the Google Display Network

Your Advertising Choices

You have several options to control personalised advertising:

• Visit Google's Ads Settings to manage your preferences
• Opt out via aboutads.info (Digital Advertising Alliance)
• Install the Google Analytics Opt-out Browser Add-on
• Adjust your cookie preferences through your browser settings

If you opt out of personalised advertising, you will still see advertisements on our site — they simply will not be tailored to your interests. For more information, see How Google uses data from sites that use Google services.

Adsterra

Adsterra is an advertising network operated by Adsterra Ltd. We use Adsterra to display additional ad formats on our site, including popunder ads and banner ads. Adsterra may use cookies, pixel tags, and similar tracking technologies to deliver relevant advertisements and measure ad performance.
