ComFinCalc is built on a simple principle — your data stays with you. We don't collect it, store it, or share it.
The short version: ComFinCalc runs entirely in your browser. Every number you enter stays on your device. We have no servers that receive your salary, tax, or personal data — ever.
All tax calculations happen entirely within your browser using JavaScript. No data is sent to any server at any point during or after a calculation. When you close the browser tab, everything is gone — there is nothing stored.
This is a deliberate design choice. We built ComFinCalc as a tool you can trust because it structurally cannot collect your data.
We may collect minimal, fully anonymous analytics such as page views and country calculator visits to understand which tools are most useful. This data contains no personally identifiable information and cannot be linked back to any individual user.
If we use a third-party analytics provider, it will be one with a strong privacy track record (e.g. Plausible or Fathom), and we will update this page accordingly.
We load fonts from Google Fonts. Google may log the font request. See Google's Privacy Policy.
ComFinCalc does not run ads and has no advertising trackers, retargeting pixels, or third-party marketing scripts.
There are no Facebook pixels, Twitter cards, or other social tracking scripts embedded on this site.
If this policy changes, we will update the date at the top of this page. Since we collect nothing, any changes are unlikely to affect you in any meaningful way.
