Your salary numbers never leave your device. The calculator runs entirely in your browser — nothing you type is transmitted to, or stored on, any server. There are no accounts and no forms.
We may use standard aggregate analytics (such as Google Analytics) to understand overall traffic — pages visited, approximate region, device type. If we later show ads (such as Google AdSense), the ad provider may set cookies as described in its own policy, and this page will be updated to say so.
