About Us & Methodology
Aftara Tools is a collection of free online tools built by Aftara, a software company. We make practical tools for students, professionals and developers, from everyday calculators and unit converters to text and code utilities. Our goal is simple: tools that are fast, clear and easy to use on any device, in your own language. If you have a question or a tool request, contact us at aftaratech@gmail.com.
Our Mission
Our mission is to provide fast, reliable, and privacy-respecting tools for everyday tasks. Whether you're a developer needing to encode a JWT, a homeowner calculating mulch volume, or just trying to figure out a discount, we've built a robust tool for you.
Our Methodology
We believe in transparency and accuracy, particularly for financial and health-related tools (Your Money or Your Life topics). Here is how we ensure our tools are reliable:
Standardized Formulas
All financial calculators (like ROI, Mortgages, and Loans) use industry-standard amortization and compound interest formulas.
Medical Guidelines
Health calculators (like BMI and BMR) use globally recognized equations, such as the Mifflin-St Jeor Equation for metabolic rate, and the standard WHO classifications for BMI.
Privacy First
Your data never leaves your browser. All calculations, hashing, and conversions happen locally on your device via JavaScript. We do not store or transmit your inputs.
Continuous Testing
Our toolkit is rigorously tested to ensure edge cases (like zero values or invalid inputs) are handled gracefully without crashing.
Editorial Guidelines
Every tool page is designed to be self-explanatory. We prioritize usability and clear instructions over cluttered interfaces. If an equation has limitations (like the Navy Body Fat method being an estimation), we clearly note it on the tool page.
