This page explains which cookies and similar technologies this website uses, what each one is for, and how long it stays on your device. For everything else we do with personal data, see our privacy policy.
What a cookie is
A cookie is a small text file a website asks your browser to store. It lets the site remember something between page loads: that you already dismissed a banner, which language you read in, or that this visit belongs to the same session as the last page you opened. Some cookies are set by us, others by services we use.
The categories we use
Strictly necessary. These make the site work at all: serving pages, keeping your session consistent, and remembering your cookie choice so you are not asked again on every page. They do not need your consent, because the site cannot function without them.
Statistics. These tell us how the site is used: which lessons people finish, where readers arrive from, which pages fail them. We use this to decide what to write next and what to fix. They only run if you allow them.
Marketing. Set by third parties to build a profile of your interests across websites. They only run if you allow them.
Changing your mind
Your choice is stored for a year, and you can change it whenever you like. Use the link in the declaration at the bottom of this page to withdraw or adjust your consent. You can also clear cookies directly in your browser, under settings, usually filed as "privacy" or "site data". Blocking the strictly necessary ones will break parts of the site.
Questions
Anything unclear, or want to know exactly what we hold on you? Write to privacy@rollo.ai. Your rights, and how to exercise them, are set out in our privacy policy.
The full, current list
The declaration below is generated by Cookiebot from an actual scan of this site, so it is the live list rather than a copy that goes stale. It names every cookie, its provider, its purpose and how long it lasts.
