Frequently Asked Questions
Is BytePad really free?
Yes — 100% free, forever. No premium tiers, no "unlock full results" prompts, no hidden fees. We sustain the site through minimal, non-intrusive display ads.
Do I need to create an account?
Nope. Open any tool, enter your numbers, get your result. No email, no password, no tracking. Your data stays on your device and is never sent to our servers.
How accurate are the calculations?
Every tool is built with real formulas from authoritative sources — financial institutions, scientific literature, and engineering standards. Results are cross-validated against known benchmarks. For critical decisions (medical, legal, financial), always consult a qualified professional.
Why is it called BytePad?
Because every calculation is a bite-sized piece of data — a "byte" — and we give you the digital "pad" to work them out on. Plus, it sounds cool. 😎
