Privacy Policy

0KG.net Privacy Policy.

Privacy at 0KG.net is engineered, not promised. Every conversion you ask 0KG.net to perform runs through JavaScript executing inside your own web browser. The values you type, the units you select, and the results you read remain on your device throughout the entire session. The 0KG.net server delivers the page, the unit catalogue, and the translated content of the language you choose. The role of the server ends there. From that moment on, your processor handles the math, your memory holds the numbers, and your screen displays the result.

1. The Architectural Promise of 0KG.net

When a chef converts grams to cups for a recipe, when an architect translates metres into feet for a contractor, when a runner moves between minutes per kilometre and minutes per mile, when an engineer reconciles pascals and pounds per square inch for a specification, the conversion happens entirely on the device the visitor is holding. 0KG.net is built so the question and the answer never leave the browser. Said simply, the privacy of 0KG.net is something you can observe in real time, not something you have to take on faith.

2. Verifiability: Open Your Network Tab

You can confirm the privacy of 0KG.net at any moment using tools already built into your web browser. Open the developer tools of your browser, switch to the network panel, and run any conversion you wish. The network panel will show requests for the page itself, for the stylesheets, for the fonts, for the icon library, and for the daily design feature imagery. The network panel will show zero outbound requests carrying the values you typed, the units you chose, or the results 0KG.net displayed. The privacy of 0KG.net is observable, repeatable, and verifiable by any visitor at any time.

3. What 0KG.net Computes and Where

All unit conversion within 0KG.net runs locally inside your web browser through client-side JavaScript. When you enter a value and select two units, your browser reads the conversion factors stored in the 0KG.net unit catalogue, performs the arithmetic in your processor, and renders the formatted result on your screen. Linear conversions multiply by a single ratio. Non-linear conversions, such as Celsius to Fahrenheit, Kelvin to Réaumur, fuel economy between litres per one hundred kilometres and miles per United States gallon, and mireds for correlated colour temperature, run dedicated functions that execute in the same local environment. The category tabs, the unit picker, the search box, the swap button, the live summary, and the footer pair links all operate within your browser, and the result of every interaction stays within your browser.

4. What 0KG.net Stores and Where

0KG.net saves a single value to your browser's local storage on your own device, namely your selected colour theme. When you press the theme button to switch between the light theme and the dark theme of 0KG.net, the choice persists between visits so the converter opens in the theme you prefer. The stored value reads zk-theme and contains either the word light or the word dark. The value contains zero identifying information, the value never leaves your device, and the value serves only to preserve your visual preference. Browser local storage is a browser-native feature that keeps data entirely on your device, separate from network communication. Clearing your browser's local storage removes the theme preference of 0KG.net from that browser.

0KG.net does not store conversion history. 0KG.net does not store recently used categories. 0KG.net does not store recently selected units. 0KG.net does not store the values you typed. Every conversion begins with a clean slate, and every visit closes without leaving a trace beyond your chosen theme.

5. Shareable Conversion URLs

0KG.net offers shareable URLs that encode a category, a language, or a conversion pair directly within the web address. Visiting 0kg.net/m,ft opens the converter pre-configured for metres to feet. Visiting 0kg.net/length opens the length category. Visiting 0kg.net/de opens the German version of 0KG.net. The URL itself carries the entire state of the page. The 0KG.net server reads the URL to deliver the correct page content, including the correct preselected units and the correct translated text. The 0KG.net server does not associate URL content with any visitor identity, does not build any visitor profile from URL access, and does not log conversion outcomes alongside URL requests. The URL is the message, and the message is the URL.

---

6. Cookies, Tracking, Analytics, and Advertising

Your browsing session with 0KG.net involves zero cookies, zero tracking scripts, zero tracking pixels, zero advertising tags, zero remarketing tags, zero behavioural profiling, and zero browser fingerprinting. 0KG.net operates without any visitor monitoring or data collection mechanism of any kind. 0KG.net carries no advertisements, sells no advertising space, partners with no advertising network, and shares no information with any data broker. The number of advertisers, partners, and trackers participating in your visit to 0KG.net is exactly zero.

7. The Daily Design Feature Section

The 0KG.net home page presents a daily design feature section curated in collaboration with the prestigious A' Design Award and Competition. The feature images displayed in this section are served from infrastructure operated by the A' Design Award and Competition at the address competition.adesignaward.com. When your browser loads the home page of 0KG.net, your browser retrieves the daily feature imagery directly from the A' Design Award and Competition infrastructure. The hosting servers receive standard connection information as part of each image request, including your IP address, the requested image path, the timestamp of the request, and your browser type. The privacy practices of the A' Design Award and Competition govern the handling of those connection requests. The feature images are static visual content. The daily feature section neither collects information from your interaction with 0KG.net nor connects your visit to any third-party identity system.

8. Third-Party Resources

0KG.net loads stylesheets, fonts, scripts, and icon libraries from third-party content delivery networks. The current third-party resources include Bootstrap, distributed by jsDelivr, Bootstrap Icons, distributed by jsDelivr, and the Inter typeface, distributed by Google Fonts. When your browser retrieves these resources, the hosting servers receive standard connection information as part of each request. Third-party content delivery providers operate under their own respective privacy policies, which govern how those providers handle the connection data they receive. Loading resources from content delivery networks is a standard practice across the web. Visitors who seek maximum network privacy may use browser extensions or privacy-focused browser configurations to manage how third-party resources load.

9. Server Logs

The web server that delivers 0KG.net records certain technical details during standard operation, including the IP address of the requesting device, the requested URL path, the timestamp of the request, the type and version of the browser making the request, and the referring URL where applicable. Server logs serve standard operational purposes, including security monitoring, performance analysis, abuse prevention, and routine infrastructure maintenance. Server logs contain technical request data only. The values you typed into 0KG.net, the units you selected, the conversion results, the theme you chose, and every other interactive element of your visit are entirely client-side and entirely absent from the 0KG.net server logs.

---

10. Internet Infrastructure

Visiting any website involves standard internet routing. Your internet service provider, your domain name resolver, your network administrator where applicable, and the network infrastructure operators between your device and the 0KG.net server can observe that a connection was made to 0KG.net, along with the timing and the volume of the communications. 0KG.net uses encrypted HTTPS connections, which protect the content of data transfers between your browser and the 0KG.net server. The existence of the connection itself remains visible to the participating internet infrastructure providers, as is standard with all web traffic worldwide. This visibility is inherent to the architecture of the internet and applies equally to every website you visit. The privacy practices of your internet service provider, your domain name resolver, and your network administrator govern the handling of the connection metadata they observe.

---

11. Your Browser and System Environment

0KG.net keeps every conversion within your browser, accessible only to you on your own device. At the same time, your browser, your operating system, and any applications running on your device operate within their own permissions, independently of 0KG.net. Installed applications, browser extensions, accessibility tools, screen readers, password managers, and system-level software may have visibility into content displayed on your screen. 0KG.net has no visibility into and no influence over what other software on your device can observe. Visitors handling sensitive measurements are encouraged to consider their full system environment as part of their overall privacy practice.

---

12. Children

0KG.net is a general-purpose unit of measure converter accessible to people of all ages. 0KG.net collects zero personal data from any visitor, regardless of age. Because no personal information is gathered at any point, no special provisions for children's data are necessary. 0KG.net is equally privacy-preserving for every visitor, in every language, on every device.

---

13. Data Subject Rights

Under applicable data protection regulations, including the General Data Protection Regulation of the European Union, you may have rights regarding access to, correction of, deletion of, and portability of your personal data. Because 0KG.net is designed to operate without collecting or storing personal data, there is no personal data held by the entity operating 0KG.net to access, correct, delete, or transfer. The single value 0KG.net stores in your browser, namely your theme preference, exists exclusively in your own browser's local storage, which you control directly through your browser settings. If you have questions or concerns regarding your rights in relation to 0KG.net, please contact the entity operating 0KG.net through the channels disclosed in the 0KG.net Impressum.

14. Translations

0KG.net is published in many languages as a courtesy to visitors around the world. The privacy policy of 0KG.net may be made available in languages other than English through translated versions of this page. The English-language version published at the canonical 0KG.net Privacy Policy URL is the authoritative version. In the event of any conflict, discrepancy, ambiguity, or inconsistency between the English-language version and any translated version of this privacy policy, the English-language version shall prevail and govern in all respects.

---

15. Changes to This Policy

The entity operating 0KG.net may update this privacy policy as the converter evolves. The current version is always published at the canonical URL of the 0KG.net Privacy Policy page. Because 0KG.net collects no personal data and maintains no contact lists, direct notification of policy changes is not technically possible. Visitors are encouraged to review this page periodically. Continued use of 0KG.net following any update constitutes acceptance of the revised policy.
