This Cookie Policy explains how Muster App Ltd ("we", "us", or "our") uses cookies and similar technologies on our website and within the Muster application (the "Service").
What Are Cookies
Cookies are small text files stored on your device when you visit a website. They are widely used to make websites work more efficiently and to provide information to the site owners. Similar technologies include localStorage and sessionStorage, which allow websites and applications to store data locally on your device.
Cookies We Use
Our website uses only essential cookies required for basic functionality. We do not use advertising, analytics, or tracking cookies.
We measure how many people visit each page of our website with Umami, a privacy-focused analytics service. Umami sets no cookies, stores nothing on your device, and does not collect personal data or follow you across other websites.

The Muster App Service
The Muster iPad application uses browser localStorage to store essential operational data on the device. This data never leaves the device and is required for the application to function.

Third-Party Services
Our website uses Umami (described above) to count page visits. It sets no cookies and collects no personal data. We do not embed any advertising or cross-site tracking services on our website, and none within the application. No third-party cookies are set.
Managing Cookies
You can control and manage cookies through your browser settings. Most browsers allow you to:
- View what cookies are stored and delete them individually

Please note that blocking essential cookies may prevent parts of our website or application from functioning correctly.
Do Not Track
We do not track users across third-party websites and therefore do not respond to Do Not Track (DNT) signals. We do not use any technology that tracks you from one website to another.
