About BiyoTool
What the library is designed to help with.
The library covers everyday calculations, finance and health reference tools, date and time tasks, unit conversion, text processing, generators, and practical browser utilities.
No. BiyoTool runs as a website in a modern browser, so there is no separate app or extension to install.
FAQ guide
Using the tools
How to understand inputs, assumptions, and results.
Calculators can use different formulas, assumptions, rounding rules, units, date conventions, or included costs. Compare the inputs and read each tool’s “How it works” section before relying on a difference.
Open the “How it works” section below the tool. Its Method, Understand the result, Practical tip, and Notes cards explain the calculation and important limits.
FAQ guide
Tools and calculations
What the results can—and cannot—tell you.
Many real-world results are displayed to a practical number of decimal places. Keep the original inputs and units when comparing results, especially when small differences matter.
No. BiyoTool provides calculations and reference estimates, not financial, medical, legal, tax, engineering, or regulatory advice.
FAQ guide
Privacy and browser processing
How to use local tools responsibly.
No account-based calculation history is created. If you need to keep a result, copy or download it using the options provided by that tool.
No. Local processing reduces data exposure, but sensitive credentials should still be kept out of general-purpose tools and handled only through the secure system that issued them.
