Odnyx ("we", "this site") is a free educational website. This policy explains what information is collected when you visit, and how it's used.
Information we do not collect
Odnyx does not require an account, does not collect names, email addresses, or any personal information to use the site. There is no server-side database — the site is fully static.
Local browser storage
To remember your dark/light theme preference and your quiz scores, we use your browser's localStorage. This data is stored only on your own device, is never transmitted to us or any third party, and can be cleared at any time by clearing your browser's site data for this domain.
Cookies and analytics
Odnyx does not currently use cookies or any analytics/tracking service. If this changes in the future (for example, to add anonymized traffic analytics or advertising), this policy will be updated first, and where required by law, a cookie-consent notice will be shown.
Advertising (future)
Odnyx may display advertising in the future through third-party ad networks (such as Google AdSense). If and when ads are enabled, those networks may use cookies or similar technology to serve relevant ads, and this policy will be updated to name the specific providers used and link to their own privacy policies.
Third-party embeds
Lesson pages may embed videos from YouTube. When a YouTube video is loaded, YouTube (Google) may set its own cookies and collect data according to Google's Privacy Policy. We do not control or have access to that data.
Changes to this policy
We may update this policy as the site grows. The "Last updated" date at the top of this page will reflect the most recent change.
