Cookie Policy

Last updated 07/11/2026

This notice covers the website of the School of Applied Mathematical and Physical Sciences (SEMFE) at NTUA.

What cookies are

Cookies are small files stored by your browser on your device. They can support a service, recognise visits or measure its use. Reading the School's public pages does not require an account or sign-in.

Visitor statistics

The website supports Google Analytics 4. When enabled, it loads only after you accept analytics and sends usage information to Google, such as page views and browser and device information. It may store _ga and _ga_<identifier> cookies to distinguish visitors and sessions. Their default lifetime is two years, although browser restrictions and service settings can shorten it.

Read more about Google Analytics cookies and Google's privacy policy.

Third-party content

Some pages include maps, calendars or content from other services. When that content loads, your browser connects to its provider, which receives information such as your IP address and may use cookies under its own policy.

The homepage tour video uses YouTube's privacy-enhanced mode in the default configuration. Its player loads when you select Play, although its preview image may already have loaded from Google. This mode does not prevent all transfers of data to Google.

Your choices

The cookie notice lets you accept or reject analytics with equal ease. Ignoring or closing it does not count as acceptance. Before acceptance, Google Analytics does not load and no measurements are sent to it. Your choice is stored in your browser (localStorage, semfe.analytics-consent.v1) for 180 days solely to remember your preference. If browser storage is blocked, your choice lasts only for the current visit until a full reload. You can change your choice or withdraw consent using “Cookie settings” in the footer. Withdrawal disables collection, deletes accessible Google Analytics cookies and reloads the page. Accepting analytics does not enable advertising personalisation. This choice applies only to Google Analytics: embedded maps, calendars and videos operate separately as described above. Browser settings also let you delete or block third-party cookies, which can affect embedded services.

Google also provides a Google Analytics opt-out add-on for compatible browsers.
