Cookies and technical data guidelines

Cookies are small files stored by your browser. TuToSite also uses local / session storage (for example language preference or an admin preview mode) to remember settings without expanding server-side profiles.

We use technical mechanisms needed to:

• Keep an authenticated session through Supabase Auth (securely handled session tokens).
• Remember your language choice or automatic detection mode.
• Support security (abuse prevention and session integrity).
• Temporarily store interface preferences for signed-in users (for example an admin “view as user” mode).

TuToSite does not set its own advertising cookies or retargeting networks. We do not sell browsing data to advertisers.

Server or hosting logs may be produced for reliability and security; they are not used to build advertising profiles.

When you play a lesson, the browser loads YouTube’s privacy-enhanced embed (`youtube-nocookie.com`). This limits advertising cookies compared with the standard embed, but YouTube may still set cookies or read identifiers related to playback—especially if you are signed in to Google.

Those processes are controlled by Google / YouTube. Use their settings and your browser controls to manage preferences.

You can clear or block cookies and wipe local storage in your browser settings. Blocking essential cookies may break sign-in or some preferences.

For YouTube-related cookies, use Google’s controls together with your browser options.
