Universe in Problems:Privacy policy

This page describes the services currently used by Universe in Problems.

Reading and technical information

You can read the problem collection without creating an account. The hosting server records technical request information in access logs to operate the website and investigate errors and abusive traffic.

Cookies and accounts

MediaWiki uses cookies for login sessions and preferences. A short browser-check cookie is also used to protect service pages from automated traffic. Usernames and contribution histories may be visible on public wiki pages. Avoid placing private information in page content or edit summaries.

Usage statistics

The site uses Google Analytics 4 to understand how the collection is used. Your browser communicates with Google when the Analytics script loads. See how Google uses information from sites using its services and Google's Privacy Policy. Browser settings and Google's Analytics opt-out add-on provide controls for Analytics in your browser.

The website also maintains page-view counters locally. These are displayed as usage totals and do not identify individual readers.

External resources

Mathematical notation is rendered with MathJax loaded from the jsDelivr CDN. Loading an external resource connects your browser to its provider. Links to papers and other websites open services with their own privacy policies.
