Most cookie policies are long because the site has a lot to confess. Ours is short: we use cookies to keep you signed in and to remember your language, we save your unfinished work on your own device, and we set no advertising cookies.
This policy exists in English and in German (Cookie-Richtlinie). Both versions are complete and equally authoritative.
We set no advertising cookies. There are no social media pixels, no tracking across other websites and nothing shared with data brokers.
What we store on your device is mostly what the site needs in order to work: the cookies that keep you signed in, a cookie that remembers your language, and your unfinished work in your browser so you do not lose an exercise if the page reloads. Storage that is strictly necessary to provide what you asked for needs no consent under the ePrivacy rules (Art. 5(3) of the ePrivacy Directive; in the Czech Republic § 89(3) of the Electronic Communications Act, in Germany § 25(2) no. 2 TDDDG).
We also measure how the site is used. That is not needed to provide the service, so it is listed separately, in Usage statistics.
Alongside the cookies, we use your browser’s local storage — a place where a site can keep data on your own device. It stays on your computer; it reaches us only when you submit the work it holds. We use it for:
prep:attempt:…) — which question you are on and what you have answered in Lesen, Hören or a Modellprüfung, so a refresh or an accidental back button does not wipe your work;prep:writing:…, prep:vortrag:…), for the same reason;prep:vortrag-feedback:…), so that reloading the page shows it again instead of running the marking a second time;prep:einstufungstest:pending), so that it can be saved to your account after you sign up or sign in;wortschatz:…) — which cards you already know;ecp:resume-after-purchase) — the page you were on, kept for six hours;classroom.pick.sound).You can clear all of it at any time through your browser’s “clear site data” setting. Doing so only loses unfinished work saved on that device — your account and your completed attempts are stored on our servers and are not affected.
These tell us how the site is used. They are not needed to give you the service.
What these record, why, for how long and how to object is explained in our Privacy Policy.
We embed no advertising networks, no social media widgets and no third-party video players, and we serve our fonts from our own server, so no other company sets cookies through our pages as you browse.
Exceptions apply where you leave our pages or choose a feature run by someone else:
Every browser lets you view, block and delete cookies and local storage, usually under Settings → Privacy. You can block ours if you wish.
Be aware of the trade-off: because the sign-in cookies and the saved work are strictly necessary rather than optional, blocking them will stop you from signing in and from saving your work, and some exercises may not work at all. That is a technical fact rather than a choice we made.
We will not add advertising cookies or tracking by other companies quietly. If we ever did, we would ask for your consent first, through a banner where refusing is as easy as accepting, and nothing would be set until you agreed. This page is updated on the same day as anything it describes.
