Privacy policy

This site is run by the Ukrainian Olympiad in Informatics Federation, the organiser of the Ukrainian olympiads in informatics. Questions about this policy or about your data: contact@uoi.ua.

In short

By default this site sets no cookies and loads no third-party scripts. That changes only when you press “Accept” in the cookie banner yourself. Our servers keep an access log for 30 days — see Logs.

If you have accepted, the site loads Google Analytics 4 (measurement ID G-TDFWNHK90W). Until then no request is made to Google at all.

Google Analytics sets cookies named _ga and _ga_*, and sends Google LLC anonymous information about your visit: which pages you viewed and when, where you arrived from, your approximate location derived from your IP address, and your device and browser type. We use it to understand which parts of the site people need. We do not use it for advertising — the site carries no advertising of any kind.

We also load the Google Ads tag (AW-18411802920). It only counts clicks on the registration button on olympiad pages, so that we know whether our ads in Google Search work. Its _gcl_* cookies are set for uoi.ua only, not for brama.uoi.ua. Ad personalisation and Google Signals are off. We do not send Google any participant profile or Brama application, and we do not link advertising identifiers to applications. The link to Brama carries no marks.

Google acts as a processor of this data and may process it outside Ukraine and the European Economic Area.

At the bottom of every page there is a “Cookies” button that reopens the question. If you choose “Reject”, the Google Analytics and Google Ads cookies are deleted and the scripts are no longer loaded. Anyone who earlier accepted analytics only will be asked again.

Refusing is exactly as easy as accepting: both buttons in the banner are the same size and the same style, and each is a single click. If you simply close the page, nothing loads — doing nothing here means no.

Logs

For security, our servers log every request: the time, your IP address, the page address and your browser type. The logs are stored with Amazon Web Services and deleted after 30 days.

Requests for files on static.uoi.ua, ai.uoi.ua, oi.in.ua and ejoi.org are logged the same way, including the images and documents that this site’s pages load.

Olympiad participants’ data

The “Database” section publishes the names of participants in the Ukrainian olympiads in informatics, their schools, years and results. These are official competition results, and publishing them is part of running the olympiad.

If you are a participant or a participant’s parent and want to correct an error in your data or discuss its removal, write to contact@uoi.ua.

Your rights

You may ask for access to your data, for it to be corrected or deleted, and you may object to its processing. Write to contact@uoi.ua and we will answer.

Children

The main audience of this site is schoolchildren. That is why analytics and measurement here are off until they are deliberately turned on. The site shows no advertising and uses no remarketing or personalisation. Google Ads only counts clicks on the registration button after consent, so that we know whether our ads in Google Search work.

Changes
