Burnjet is an independent suite of practical web utilities, financial calculators, document creators, and cognitive mini-games that run entirely inside your browser. Every calculation and document export executes locally on your device without sending your inputs to a remote server.
When you calculate an investment, format confidential JSON, or build a resume, the code executes directly in your browser memory via JavaScript and WebAssembly. Your numbers, financial data, and resume text never touch our servers or databases. When you close the browser tab, your temporary data stays on your machine.
Yes. All calculators, developer helpers, games, and document tools (including PDF resume and invoice exports) are 100% free. There are no usage quotas, no email paywalls, and no watermarks added to your downloaded files.
Financial calculators use standard mathematical compounding models (such as future value compounding formulas for SIP and CAGR). Tax tools (such as TDS and slab calculators) follow verified provisions under the Indian Income Tax Act. All math is deterministic and verifiable.
No. Burnjet has zero user account friction. You never need to enter an email, create a password, or confirm a token. Just open the tool you need, enter your values, and download or copy the result.
