Cookies and local storage
PTEGRO may use browser storage technologies to remember study progress, preferences and app state on your device. The current app's progress features primarily use local browser storage rather than a cloud user account.
Hosting and essential technology
Our hosting or form provider may use technical cookies or similar technologies necessary for security, fraud prevention, delivery and form processing. These technologies can be controlled by the relevant provider and browser.
Analytics and advertising
If we later introduce non-essential analytics, advertising or marketing technologies that require consent under applicable law, this policy and the site's consent controls should be updated before those technologies are enabled for affected users.
Your controls
You can clear or restrict cookies and site storage through your browser settings. Clearing local site data may also erase locally stored study progress or preferences.
