This policy explains which cookies the website of the Department for Language Education and Sport (DEOS), Medical University of Sofia, uses, what they are for, and how you can manage your choice.
What are cookies?
Cookies are small text files stored by the site in your browser. They do not contain your name, e-mail address or password. Some are needed for the site to work; others are optional.
Cookies we use
| Name | Purpose | Duration | Category |
|---|---|---|---|
deos_admin |
PHP session: administrator sign-in, CSRF protection, maintenance preview. Normally set only for administrators. | Until the browser is closed | Essential |
deos_contrast |
Remembers whether the high-contrast mode is on. | 1 year | Functional |
deos_consent |
Remembers the choice made in the cookie banner, so it is not shown on every visit. | 6 months | Essential |
deos_vt |
Random token used for the “online now” and unique-visitor counters. | Until the browser is closed | Statistics — only after “Accept all” |
deos_vd |
Date of the last counted visit, so one browser is not counted twice in a day. | 2 days | Statistics — only after “Accept all” |
Essential cookies
These cookies cannot be switched off from the banner, because the site or the administration cannot work without them. They are not used for advertising.
Statistics
The statistics cookies are enabled only after you choose “Accept all”. They produce aggregate numbers — visits, unique visitors and visitors online now. They are not used for profiling and are not shared with third parties. With “Essential only” they are not set; if they were already set, the site clears them on the next page load.
This website does not use Google Analytics.
Third-party embeds
Some publications and the sidebar contain embedded YouTube videos, Google Forms surveys and a Google Maps map. Without consent they are not loaded: you see a placeholder and can load that one embed with a button. With “Accept all” they load directly. Once an embed is loaded, the provider (Google/YouTube) may set its own cookies and receive your IP address. Those cookies are not controlled by DEOS; see Google's Privacy Policy. If you do not want this, block third-party cookies in your browser or do not load the embed.
Managing your choice
You can change your choice at any time with the “Cookies” button at the bottom of the site. You can also delete cookies from your browser settings; the banner will then appear again on your next visit.
Changes to this policy
This policy is updated whenever the cookies used by the site change.
