Frequently asked questions

Frequently asked questions about tinymath: pricing, accounts, accuracy, and what's coming.

Is tinymath free?

Yes — browsing and using the calculator templates is free.

Do I need to sign up?

No — there's no account or login yet. Every calculator template runs as soon as the page loads.

Where do the numbers I type in go?

Nowhere but your browser. There's no backend yet, so nothing you enter into a calculator is sent to or stored by tinymath.

Can I customise my own calculator?

Not yet. A block-based builder — your own inputs, operators, and pricing tiers — is in progress. For now, /build shows what's coming; start from one of the ready-made templates instead.

Can I embed a calculator on my own website?

Not yet — embedding is planned, but the mechanism (an iframe vs. a small JS snippet) isn't decided or built yet.

What industries are covered?

Ten starter templates today: printing, solar, renovation/construction, logistics, HVAC/fabrication, insurance, mortgage, tax, healthcare, and government/NGO eligibility.

How accurate is the math?

Every calculator runs on an exact-decimal engine (Rust, compiled to WebAssembly) instead of JavaScript's floating-point numbers, so results don't drift from rounding error the way plain JS math can.
