Cookie Policy
Last updated: April 21, 2026
This Cookie Policy explains how Smart Unit Converters ("we", "our", or "us") uses cookies and similar tracking technologies when you visit https://www.smart-unit-converters.com. It explains what these technologies are, why we use them, what types of cookies are set, and what choices you have. This policy should be read together with our Privacy Policy and Terms of Service.
What Are Cookies?
Cookies are small text files that a website stores on your device (computer, tablet, or phone) when you visit. They are widely used to make websites work — or work more efficiently — as well as to provide information to the owners of the site. Cookies allow a website to remember your actions and preferences (such as theme selection or language) over a period of time, so you don't have to re-enter them whenever you come back to the site or browse from one page to another.
Besides cookies, we may also use similar technologies such as local storage (a web standard that stores larger chunks of data in your browser) and web beacons (tiny transparent images used by advertising services to measure impressions). This policy treats all of these collectively as "cookies" for simplicity.
How We Use Cookies
Smart Unit Converters is designed to be privacy-friendly. All calculations happen locally in your browser, and we do not require you to sign up, log in, or provide any personal information to use our tools. The cookies we do use fall into the following categories:
1. Strictly Necessary Cookies
These cookies are essential for the Website to function correctly. They do not store any personally identifiable information. Examples include:
- A cookie or local-storage entry that remembers your chosen theme (light or dark mode).
- Session cookies that keep form inputs intact if you navigate between pages.
- Security cookies that help protect against basic automated abuse.
Because these cookies are required for the core functionality of the Website, they cannot be disabled through our cookie controls. You may still block them at the browser level, but the Website may not work correctly as a result.
2. Analytics Cookies
We may use privacy-respecting analytics tools to understand how visitors interact with our Website — which pages are most useful, how long visitors stay, and where they come from. This data is aggregated and anonymous, and helps us improve the Website for everyone. If used, analytics cookies are typically set by services such as Google Analytics, with IP addresses anonymized where technically possible.
3. Advertising Cookies
Smart Unit Converters may display advertisements served by Google AdSense and its partners. Advertising cookies and similar technologies are used to:
- Serve ads that are relevant to you based on your interests and the content you view.
- Limit the number of times you see the same ad.
- Measure the effectiveness of advertising campaigns.
- Detect and prevent click fraud.
Google, as a third-party vendor, may use cookies (such as the NID and DoubleClick cookies) to serve ads based on your prior visits to this Website and other websites. You can opt out of personalized advertising by visiting Google Ads Settings, or learn more about interest-based advertising at aboutads.info and youronlinechoices.eu (for European users).
Third-Party Cookies
In addition to our own cookies, we may use various third-party cookies to report usage statistics, deliver advertisements, and so on. These third parties may include Google AdSense, Google Analytics, and embedded content providers. Each third party has its own privacy and cookie policies, which we encourage you to review.
Managing Your Cookie Preferences
You have full control over which cookies your browser accepts. Most web browsers allow some control of most cookies through browser settings. To find out more about cookies, including how to see what cookies have been set and how to manage or delete them, visit allaboutcookies.org.
Typical browser cookie controls can be found here:
Please note that if you choose to block or delete cookies, some features of our Website (such as theme preferences) may no longer work as intended, and you may still see advertising — just less relevant to you.
Do Not Track Signals
Some browsers include a "Do Not Track" (DNT) feature that signals to websites you visit that you do not want to be tracked. Because there is not yet a common understanding of how to interpret DNT signals, our Website does not currently respond to them in a specific way. We follow the cookie preferences you set in your browser itself.
Changes to This Policy
We may update this Cookie Policy from time to time to reflect changes to the cookies we use, or for other operational, legal, or regulatory reasons. The "Last updated" date at the top of this page will be revised accordingly. We encourage you to check this page periodically to stay informed about our use of cookies.
