1. What are cookies?

Cookies are small text files stored on your device when you visit a website. Cookies help the Platform remember information about your session and your preferences, which improves your experience. In addition to cookies, we may also use similar technologies such as local storage.

2. Types of cookies we use

OpenSTEM LMS uses cookies only to the minimum extent needed to operate. They fall into the following groups:

Cookie typePurposeRequired
Essential cookiesKeep you signed in, authenticate users and make sure core functions work securely.Yes
Functional cookiesRemember your preferences, such as language, display mode and personal settings.No
Security cookiesHelp prevent fraud and protect forms (for example, anti-bot verification when you sign up or sign in).Yes
Performance & analytics cookiesHelp us understand how users interact with the Platform so we can improve the service. The data is aggregated and anonymous.No
Advertising cookiesMeasure the effectiveness of advertising campaigns (knowing which ad a registration came from) and limit repeat display of content you have already seen. Set only after you consent, and never set in the students’ learning area.No

3. Third-party cookies

Some features of the Platform rely on third-party services (for example, authentication services, anti-bot verification, or content embedded from external sources). These parties may set their own cookies under their own policies. We encourage you to review the privacy policies of the relevant third parties.

When you consent to analytics or advertising cookies, the following services may set cookies: Google (Google Analytics, Google Ads) and Meta (Facebook Pixel). If you do not consent, we do not load these services.

4. Managing cookies

On your first visit, you will see a notice that lets you choose each group of non-essential cookies. We do not turn any group on by default — you must actively consent before analytics and advertising cookies are set. Your choice is recorded together with the time and the policy version.

You can change your mind at any time. Click the button below to withdraw your current choice and choose again from the start — we stop using analytics and advertising cookies as soon as you click, without waiting for you to finish choosing.

You can also control and delete cookies through your browser settings. Most browsers let you block or delete existing cookies. Please note, however, that disabling essential cookies may stop some important functions (such as signing in) from working properly.

How to manage cookies in popular browsers:

  • Google Chrome: Settings → Privacy and security → Cookies.
  • Mozilla Firefox: Settings → Privacy & Security.
  • Safari: Preferences → Privacy.
  • Microsoft Edge: Settings → Cookies and site permissions.

5. Relationship with the Privacy Policy
