1. 100% Local Processing Guarantee
Your privacy is the core architectural principle of OnlineUnitCalc. We guarantee that every tool on this platform processes your data 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 are never transmitted to, stored on, or analyzed by our servers.
2. Data Collection
Because our tools operate entirely on the client side, we do not require accounts, logins, or registration. We do not collect, harvest, or sell any personal data.
We may use standard analytics software (such as server logs or anonymous analytics tools) strictly to count total page visits and understand aggregated traffic patterns (e.g., which tool is most popular). This data is anonymized and cannot be used to identify individual users or access the content they 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.
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. Because we do not collect email addresses, we cannot notify users directly of updates, so we encourage you to review this page periodically.
