Cookie Policy
What cookies are, and how Material-Sim uses them. The short version: this website sets none, and the application uses only what it needs to keep you signed in.
Last updated 4 August 2026 · Version 1.0
1What cookies are
Cookies are small text files a website can store on your device. They are widely used to make sites work, to keep you signed in, and — on many sites — to measure usage or show advertising. Similar technologies such as local storage do comparable things.
2This website
material-sim.com sets no cookies. We use no analytics, no advertising or tracking pixels, and no third-party scripts that profile you. Your light/dark theme choice is applied in the page for your visit and is not stored in a cookie.
Because we set no non-essential cookies here, there is no cookie banner to accept or reject.
3The application
When you sign in to the Material-Sim application at app.material-sim.com, we use a small number of strictly necessary cookies. These are required for the application to work and do not need consent under the law. We do not use advertising or cross-site tracking cookies.
| Cookie | Purpose | Type | Retention |
|---|---|---|---|
| Session | Keeps you signed in as you move between pages | Strictly necessary | Session / short-lived |
| Security token | Protects against cross-site request forgery (CSRF) | Strictly necessary | Session |
| Preferences | Remembers in-app settings such as theme, if you set them | Functional | Up to [12 months] |
Exact cookie names and lifetimes will be confirmed against the live application before general availability. [Confirm the application's actual cookie list here.]
4Managing cookies
You can control or delete cookies through your browser settings, and set your browser to block them. Guidance is available at aboutcookies.org. Note that blocking strictly necessary cookies will stop you being able to sign in to and use the application.
5Changes
If we introduce new cookies — for example analytics to help us improve the product — we will update this policy first, and where the law requires consent we will ask for it through a cookie banner before setting them.
