Privacy policy
The site collects as little as possible. In most cases, nothing at all.
Updated November 11, 2026.
Who is responsible
The duorolt.com editorial team. For privacy questions, write to contato@duorolt.com.
What the site collects
Browsing. Our pages do not set cookies and do not load analytics, advertising or tracking scripts. We do not build profiles of readers.
Contact form. If you write to us, we receive the name, email address, subject and message you type. We use them only to reply. The form sends the message by email, and the site does not store it in a database.
Quiz and Star map data. Your stars, your round totals, an unfinished round and your theme choice (dark or light) are saved in your browser's local storage. They are not sent to any server, and we cannot see them. The site also remembers, in the current tab only, which guides you opened (session storage). See the cookies page for the details. You can erase everything with the "Delete my data" button on the Star map.
Technical logs. The web host and the network that delivers the site may keep standard technical logs, such as IP address, time, browser and the page requested, to run and secure the service. We do not use them to identify readers.
Outside links and resources
Fonts and images are served by this site. Links to agency pages and other sources lead to third-party sites with their own privacy policies.
Your choices
You can ask us what we hold about you, ask us to correct it or ask us to delete it. For the contact form, that means the messages you sent. Write to contato@duorolt.com. Where laws such as the California Consumer Privacy Act or the EU General Data Protection Regulation apply to you, those rights are honored the same way.
Children
The site is educational and open to students, but it is not directed to children under 13, and we do not knowingly collect personal information from them. Reading the guides and playing the quiz require no personal data. If you are under 13, ask a parent or guardian before using the contact form.
Changes
If we ever add ads, analytics or cookies, we will update this page and the cookies page before turning any of them on.
