Privacy Policy
Last updated: 11 October 2026
In short: we collect only what you type into our forms, plus the technical data needed to deliver and protect the website. We use it to send you the software, answer your questions, and, only if you agree, send occasional product news. We don't sell your data or use advertising trackers.
The Phasix desktop application runs on your computer and does not send your calculations, compositions, or any other data to us.
1. Who we are
Fluivix is a trading name of Shoeb Khan, who is responsible for your personal data (the "controller") under this policy. In this policy, "Fluivix", "we", and "us" refer to him.
Contact for all privacy questions and requests: [email protected]

It is strictly necessary for that feature and is used only by the download service.fluivix-theme(browser local storage): remembers your light or dark display choice.- Cloudflare Turnstile: when you use a form, Cloudflare checks browser and device signals to tell people from automated programs. See Cloudflare's privacy policy.

- Cloudflare, Inc.: website hosting, database, file storage, security checks, and email forwarding

If we start accepting online payments, the payment provider will process payment details as a separate seller or processor, under its own privacy policy. We will update this page before that happens.
These providers may process data outside your country, including in the United States. Where the law requires it, transfers are covered by the provider's standard contractual protections.
