1. Local Tool Processing
Your privacy is a core architectural principle of OnlineUnitCalc. Every tool on this platform processes your input locally within your web browser. Whether you are uploading a CSV, formatting a proprietary JSON configuration file, or generating a cryptographic hash, the contents you input into our tools are not transmitted to, stored on, or analyzed by our servers for processing.
2. Data Collection
We do not require accounts, logins, or registration to use our tools. We do not collect, harvest, or sell the content you input into our tools.
We use third-party services that may collect information about your visit, including:
- Google Analytics (GA4) — to understand aggregated traffic patterns and which tools are most popular.
- Google AdSense — to display advertisements on the site.
These services may use cookies and similar technologies. The data they collect is used for analytics and advertising purposes and is governed by their respective privacy policies. This data is separate from the content you input into our tools.
3. Local Storage & Cookies
OnlineUnitCalc utilizes your browser's localStorage API to enhance your user experience. This includes saving your dark/light mode theme preference, your "Favorite" tools, and occasionally preserving your recent inputs (like the Notepad Calculator drafts) so you don't lose your work if you accidentally refresh the page.
This data is stored purely on your local hard drive. We have no access to it, and you can clear it at any time by clearing your browser's history and website data.
Third-party services, including Google Analytics and Google AdSense, may set cookies on your device for analytics and advertising purposes. You can learn more about how Google uses data from sites that use its services at Google's partner sites policy, and manage your ad personalization preferences at Google Ad Settings.
4. Changes to this Policy
We reserve the right to update this Privacy Policy at any time. Any changes will be reflected immediately on this page. We encourage you to review this page periodically for updates.
