Why In-Browser Sandbox Execution Guarantees Data Security
Traditional web utilities upload personal documents, tax identification numbers, and salary data to external web servers, creating data leak risks. Our platform utilizes native browser APIs—including the HTML5 Canvas API and Blob Memory Buffers—to perform mathematical calculations and file conversions locally. Not a single byte of your uploaded files or entered data is transmitted across the internet.

Is account registration or sign-in required?
No registration is needed. You can access all tools immediately from any modern web browser across desktop and mobile devices.
Are my images and documents stored on your servers?
Never. Image conversions and document compression execute entirely within your browser’s local memory sandbox. Files are never transmitted to external servers.
How accurate are the academic and financial calculators?
Calculators are regularly updated in alignment with statutory updates from the Central GST Council, Ministry of New and Renewable Energy (MNRE), and state education boards.
