Cookie Policy
Last updated: 5 November 2026
Celestium uses no advertising cookies, no analytics and no tracking across other websites. This page explains the small amount of data stored in your browser and why. Celestium is a product of FLYSTACK SRL.
1. What are cookies and browser storage?
Cookies are small files a website saves on your device. Local storage and IndexedDB are similar tools that keep data in your browser. Celestium mainly uses these two, not cookies.
2. Our website
The Celestium website sets no cookies and stores nothing in your browser. Its fonts are hosted with the site, so loading them does not contact another company.
3. The Celestium app
The app stores only what it needs to work. Because this is strictly necessary for the service you asked for, it does not need a consent notice.
| What | Type | Why | How long |
|---|---|---|---|
| Sign-in token | Local storage | Keeps you signed in | Until you sign out or it expires |
| Current workspace | Local storage | Remembers your workspace | Until you clear it |
| Your show idea | Local storage | Keeps the prompt you sent from our website through sign-up | Until you use or dismiss it |
| Editor preferences | Local storage | Remembers your theme, layout, timeline and viewport settings | Until you clear it |
| Show data | Local storage and IndexedDB | Keeps show files on your device so the editor is fast and work is safer | Until you clear it |
4. Other companies
- Google Fonts: the app loads a typeface from Google. This sends your IP address to Google, and Google sets no cookies through this request.
- Cesium and Google maps: when you open the 3D map, these services receive your IP address and the area being viewed.
- Cloudflare: our network provider may set a strictly necessary cookie to protect the service from abuse.
5. Your choices
You can clear cookies and site data at any time in your browser settings. Clearing it signs you out and removes preferences and any show data that has not been saved to your account.
6. Changes to this policy
If we ever add analytics or other optional cookies, we will update this page and ask for your consent first where the law requires it.
