Cookies and local storage

SQL.tn separates storage required for the service from optional audience measurement.

Necessary cookies

Session cookies secure sign-in and account access. They are required for the requested functionality and are not used for advertising.

Local learning storage

The browser may keep local progress, language preferences and SQL environment data to support resuming and operation outside the application database.

Optional audience measurement

Google Analytics is loaded only after consent. Declining does not limit courses, exercises or account access. You can change the choice by clearing the saved consent in site data.

Duration and control

Duration depends on the storage and browser settings. You can delete cookies and local data from your browser settings; this may sign you out or remove local progress.
