Privacy Policy

Last updated: August 2026

Calculator ProHub is engineered so that we cannot misuse your data — because we don't collect it in the first place.

What happens to numbers you enter

All calculations run locally in your browser via JavaScript. Your inputs are never sent to our servers for processing. When you use "Copy link", your input values are encoded into the URL itself — that link lives wherever you share it (chat apps, email), not on our systems. Avoid putting sensitive personal information into shared links.

Accounts

There are none. You can use every feature without registering anywhere.

Cookies & local storage

• Theme preference is saved in your browser's local storage.
• Analytics: when enabled, we collect aggregate, cookie-less event counts (e.g. "calculator_used") without identifiers or inputs.
• Advertising, once enabled, may involve third-party ad networks setting cookies under their own policies. See our Cookie Policy for details.

Third-party services

The currency converter fetches public ECB exchange rates via frankfurter.dev at your request. This request goes directly from your browser and contains only the currency codes — not your amounts.
