Frequently asked questions

+Is Percentage Calculator really free?

Yes. Every Berlvis tool is free, with no signup, no email and no daily quota.

+Do you upload my files or data?

Never. Your file stays in your browser, nothing is uploaded, nothing is logged, nothing leaves your device.

+Will it work on my phone?

Yes, anywhere there's a modern browser (Chrome, Safari, Firefox, Edge, Brave, Arc).

We use the same formulas you'd find in official guidance and primary tax/regulatory sources. Numbers are calculated client-side so what you see is what's used, nothing hidden.
