Privacy Policy
Last updated: July 14, 2026
Nexmetra is built with privacy as a core principle. This page explains what data our tools use and how it's handled.
Data We Collect
Our tools run entirely in your browser. Settings such as your calibration data, preferred unit, and measurement history are stored locally in your browser's storage (localStorage) and are never transmitted to our servers or any third party. This data stays on your device and is only accessible to you.
Analytics
We may use privacy-respecting, aggregate analytics to understand general site usage (such as which pages are visited) in order to improve our tools. This data does not identify you personally.
Cookies
We do not use tracking or advertising cookies. Any local storage used by our tools is strictly functional — for example, remembering your screen calibration between visits.
Third-Party Services
Our tools do not send your measurement data to any third-party service. If this changes for a future tool, this policy will be updated accordingly.
Changes to This Policy
We may update this privacy policy from time to time. Changes will be reflected on this page with an updated revision date.
