How we handle cookies, data and advertising
Last updated: July 2026
🔒 This policy explains what data voltagedrop.com.au collects, how cookies are used for analytics and advertising, and how you can control or opt out of that tracking.
The Voltage Drop Calculator (voltagedrop.com.au) is a free electrical calculator covering Single Phase AC, Three Phase AC, DC, Series Runs and Motor Starting voltage drop, provided by the team behind LightTools. This policy covers voltagedrop.com.au.
Our calculator runs entirely in your browser — the cable lengths, currents, voltages and other figures you enter are processed locally and are not transmitted to or stored on our servers. We do not require account registration and do not collect names, addresses or payment details.
We do, however, collect limited technical and usage data automatically through the analytics and advertising services described below, including your approximate location (derived from IP address), browser type, device type, pages visited, and how you interact with the site.
Cookies are small text files stored on your device. We use cookies and similar technologies (such as local storage) for the following purposes:
| Purpose | Provider | Details |
|---|---|---|
| Site analytics | Google Analytics | Measures page views, traffic sources and site usage to help us improve the tool |
| Advertising | Google AdSense | Serves ads and may personalise them based on your browsing activity |
| Preferences | First-party | Remembers calculator settings such as region or unit preferences during your session |
You can control or delete cookies at any time through your browser settings. Blocking cookies may affect how some parts of the site function, including calculator preference memory.
We use Google Analytics (Google Tag / gtag.js) to understand how visitors use our site — which pages are popular, how long visitors stay, and what devices and browsers they use. Google Analytics collects data such as your IP address (which may be truncated or anonymised), device and browser information, and pages visited. This data is processed by Google in accordance with the Google Privacy Policy.
You can opt out of Google Analytics tracking across all websites by installing the Google Analytics Opt-out Browser Add-on.
This site displays advertisements served by Google AdSense. Google and its advertising partners use cookies and similar technologies — including the DoubleClick cookie — to serve ads based on your prior visits to this and other websites, and to measure ad performance.
Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet. You may opt out of personalised advertising by visiting Google Ads Settings, or opt out of some third-party vendor use of cookies for personalised advertising by visiting www.aboutads.info. Third-party advertising vendors, including Google, use cookies to serve ads on this site based on your visits to this and other sites; further detail is available in Google's How Google uses information from sites or apps that use our services.
As disclosed in our Disclaimer, we participate in the Amazon Associates affiliate program and generate links to Takealot for South African users. Product links generated by our calculator may include affiliate tracking parameters. When you click these links, the destination retailer may set its own cookies in accordance with their own privacy policy — see the Amazon Privacy Notice. We do not control and are not responsible for cookies set by Amazon, Takealot or other linked third-party sites.
Our tool and site infrastructure rely on the following third-party services, each of which may process data under their own privacy policies:
Our tool is intended for general and professional audiences and is not directed at children under 13. We do not knowingly collect personal information from children.
Since calculator inputs are processed locally in your browser and are not transmitted to our servers, there is minimal server-side data storage risk associated with using the tool itself. Data collected via Google Analytics and Google AdSense is stored and secured by Google in accordance with their respective policies.
We may update this privacy policy from time to time to reflect changes in our practices or for legal, regulatory or operational reasons. The date at the top of this page indicates when the policy was last revised. Continued use of the site after changes are posted constitutes acceptance of the updated policy.
