# Cookie Policy

Cookies and similar technologies used on tungsten.aero and when you use Tungsten. Operated by Altus Aeronautica Ltd.

## **What we use**

We use cookies and similar technologies that are necessary for the site and contact form to work securely, and may use limited analytics where configured. This page summarises the categories you are most likely to encounter.

## **Strictly necessary **

Security and abuse prevention on the contact form uses Cloudflare Turnstile, which may set cookies or local storage as described in Cloudflare’s documentation. Session and authentication cookies are used when you sign in to the Tungsten application so we can keep you logged in securely.

## **Preferences & performance **

We may store UI preferences such as colour mode in local storage so the site remembers your choice. If we enable product analytics, they are used to understand aggregate usage and improve reliability — not to sell advertising profiles.

## **Managing cookies **

You can control cookies through your browser settings. Blocking strictly necessary cookies may prevent the contact form or sign-in from working. For personal-data rights related to cookies, see our [Privacy Policy](https://www.tungsten.aero/privacy).
