1. What Are Cookies?
Our website and platform use cookies to distinguish you from other users and to improve your experience. This notice explains what cookies are, which ones we use, and how you can control them.
A cookie is a small file of letters and numbers that we store on your browser or on the hard drive of your device. Cookies contain information that is transferred to your device and stored there. They help us provide you with a good experience when you use Studia and allow us to improve our Platform.
Information for Parents and Guardians
Because Studia is used by children, we have taken care to use only the cookies that are necessary to run and improve the Platform. We do not use advertising or targeting cookies, and we do not share cookie data with advertisers.
2. Types of Cookies We Use
We use the following categories of cookies:
Strictly Necessary Cookies
These cookies are required for the Platform to function. They enable core features such as logging in, staying logged in, processing payments securely, and protecting against certain types of online attacks. You cannot opt out of strictly necessary cookies — without them, the Platform cannot work properly.
Performance and Analytics Cookies
These cookies allow us to recognise and count the number of visitors and to understand how people use the Platform — for example, which pages are visited most often and whether any errors occur. All information collected is aggregated and anonymised where possible. This helps us improve the way the Platform works. These cookies require your consent and can be switched off in your cookie preferences.
Functionality Cookies
These cookies remember your preferences and settings — for example, your subject filters, display preferences, and where you left off in a video. They make your experience more convenient and personalised. These cookies require your consent and can be switched off, though doing so may affect some Platform features.
