Overview
This Privacy Policy explains what information is collected when you visit AllUnits.net, why it is collected, and how it is used. The site is designed to require as little personal information as possible: there are no user accounts, no newsletters, and no forms that ask for your name, email address, or other identifying details. The information described below is collected primarily to keep the service reliable, to understand which tools are useful, and to fund the site through advertising.
Information we collect
AllUnits.net itself does not directly collect personal data. When you visit the site, anonymous usage metrics are gathered through third-party analytics, including:
- Pages viewed and time spent on each page
- Device type, browser, and operating system
- Approximate region derived from your IP address
- Referring website, where available
These metrics are aggregated and used to understand general usage patterns, not to identify individual visitors.
Cookies and similar technologies
The site itself stores a single localStorage entry in your browser to remember your theme preference (light or dark mode). This entry is not transmitted to any server. In addition, third-party services embedded on the site, primarily Google Analytics and Google AdSense, may set their own cookies as described below. You can clear cookies and localStorage at any time using your browser settings.
Google Analytics
AllUnits.net uses Google Analytics to measure aggregate, anonymous traffic. This helps us see which converters and articles are most popular so we can prioritise improvements. Google Analytics may set cookies and process limited information such as an anonymised IP address. If you prefer not to be measured at all, you can install the official Google Analytics Opt-out Browser Add-on, which prevents your visits from being included in Analytics reports across all sites.
Google AdSense and advertising
The site is supported by advertising delivered through Google AdSense. Google and its partners may use cookies and similar technologies to serve ads based on your prior visits to AllUnits.net or other websites. You can manage your ad personalisation settings, including opting out of personalised advertising, at https://www.google.com/settings/ads. More information about how Google uses data for advertising is available at https://policies.google.com/technologies/ads.
Your rights
Depending on where you live, you may have rights under data-protection laws such as the GDPR in the European Union or the CCPA in California. These typically include the right to access information held about you, request deletion, opt out of personalised advertising, and request data portability. Because AllUnits.net does not collect personal data on its own servers, most of these rights are exercised directly with the third-party services that do, such as Google. Links above explain how to manage analytics and advertising preferences.
Data retention
AllUnits.net retains no personal data on its own servers. Information processed by Google Analytics and Google AdSense is retained according to Google's own retention policies, which you can review on Google's privacy pages.
International data transfers
Because Google operates globally, data processed by Google Analytics and Google AdSense may be transferred to and stored in countries outside your own, including the United States. Such transfers are governed by Google's privacy policies and applicable data-transfer mechanisms.
Children's privacy
AllUnits.net is a general-audience educational resource and is not directed at children under 13. We do not knowingly collect personal data from minors. If you believe a child has provided personal information through an embedded third-party service, please contact us and we will assist in directing you to the appropriate provider.
Changes to this policy
This Privacy Policy may be updated from time to time to reflect changes in the site, in the third-party services we use, or in applicable law. Meaningful changes will be reflected on this page, along with an updated Last updated date at the top.
