# Privacy Policy

## What we collect

This site runs free, evidence-based calculators. We collect as little data as practical, and we never sell data.

- **Traffic analytics (with your consent):** Google Analytics 4 sets cookies that store a random client identifier, so we can count visits and see which calculators are useful. If you decline, GA4 is never loaded.
- **Usage insights (no cookies):** Microsoft Clarity shows anonymized interaction heatmaps and session replays. It does not set cookies and masks all form inputs, so we never see what you type.
- **Your choice:** your accept/decline decision is stored only in your browser (localStorage) and is not sent anywhere.

## Your choice

On your first visit we ask whether analytics cookies are OK. You can change your mind any time by clearing this site's data in your browser, which brings the prompt back.

## Third parties

- [Microsoft privacy statement](https://www.microsoft.com/en-us/privacy/privacystatement)

## Changes

If this policy changes materially, we update this page and the date above.
