Introduction.
The Number System Converter ("we", "our", "the Tool") is a free, client-side web application that converts numbers between Indian and International number systems. This privacy policy describes our practices regarding data collection, use, and storage. Because our tool runs entirely in your browser with no server-side processing, our data practices are minimal by design.
Information We Collect.
We do not collect any personal information. The Number System Converter does not require you to create an account, sign in, or provide any personal details such as your name, email address, or phone number.
The numbers you enter into the converter are processed entirely within your browser. They are never transmitted to our servers or any third-party service. When you close the browser tab or navigate away, your input is gone — we have no way to access it.
How We Use Information.
Since we do not collect any personal information, there is no data for us to use, share, or sell. The tool exists to provide instant number conversions, and that's all it does.
Cookies & Local Storage.
The Number System Converter uses your browser's localStorage to remember your theme preference (light or dark mode). This is a single key-value pair stored on your device:
Key: "theme" | Value: "light" or "dark" This data is never sent to any server. You can clear it at any time by clearing your browser's local storage for this site. We do not use cookies for tracking, advertising, or analytics.
Third-Party Services.
The Number System Converter loads the following third-party resources:
- Google Fonts — We load the Inter and JetBrains Mono font families from fonts.googleapis.com to render text. Google may collect your IP address and browser information when fonts are loaded. See Google's Privacy Policy for details.
We do not integrate any advertising networks, analytics platforms, or social media trackers.
Data Security.
Since all processing happens client-side and we do not collect or store any user data on our servers, the attack surface for data breaches is minimal. The tool is served over HTTPS to ensure the integrity of the code delivered to your browser.
Children's Privacy.
The Number System Converter is a general-audience educational tool. We do not knowingly collect personal information from children under 13. Since we do not collect any personal information at all, our tool is safe for users of all ages.
Changes to This Policy.
We may update this privacy policy from time to time. Any changes will be posted on this page with an updated "Last updated" date. Your continued use of the tool after any changes constitutes your acceptance of the revised policy.
