An Advent calendar for teachers
Enter your personal code once. After that, the calendar stays open on this device until the end of January, and you won't need to sign in each time.
Your code is in the email you received after signing up. No code yet? Sign up here.
On many websites, the first thing you see is a cookie window: accept, reject, settings, even more settings. Not here. We only use the cookies the site needs to work. No advertising, no third-party analytics.
A cookie is a small text file. Our server places it in your browser and gets it back the next time you visit. That is how it knows, for example, that you are already signed in.
A crumb is an entry in your browser's storage (the so-called local storage). The site places it there itself, and it stays on your device. Our server does not see it automatically.
| Name | Purpose | When | How long |
|---|---|---|---|
| nd_zugang | remembers that you are signed in to the Teacher Portal. It contains the number of your access, the expiry date and a signature our server uses to check that the cookie is genuine. No name and no email address. | only once you enter your access code | 30 days |
| nd_lerntier | remembers that you have redeemed a code for the Learning Animal Check. It contains the number of the code, the expiry date and a signature. | only once you enter a Learning Animal code | 30 days |
| Cloudflare security cookie | Cloudflare runs our servers and may set a cookie to detect automated attacks. | only when Cloudflare considers it necessary | 30 minutes at most |
Our two own cookies are set up so that scripts on the page cannot read them, and they are only sent over an encrypted connection.
| Name | Purpose | How long |
|---|---|---|
| zugang | tells the site that it may show you the content of the Teacher Portal | until you sign out or delete it |
| geraet | a random device number, so that one access works on two devices at most (a Learning Animal code on three at most). It reveals nothing about you or your device. | until you delete it |
| ltc_geraet | the random device number for the Learning Animal Check. A Learning Animal code works on three devices at most, a single-use code on one. | until you delete it |
| ltc_codes_v1 | remembers the result codes you save with "Remember in this browser" on the results page of the Learning Animal Check | until you delete it |
| dyslexic, spacing | remember whether you have switched on the reading font or the wider line spacing | until you delete it |
| kekse_ok | remembers that you have already seen the little cookie notice, so it does not pop up every time | until you delete it |
When you buy annual access or Learning Animal codes, you are taken to Stripe's payment page. Stripe sets its own cookies there, mainly to prevent fraud. Stripe itself is responsible for these. We never see your card details.
We send our emails through Brevo. Brevo counts opens and clicks only anonymously, as a total for everyone. We cannot see who exactly opened an email or clicked a link.
You can delete all cookies and crumbs in your browser at any time:
After that, the site no longer recognizes you. In the Teacher Portal, simply sign in again. Because the site does not recognize your device, it counts as a new device. If both of your device slots are already taken, send us a short message and we will free one up.
If we ever add cookies or crumbs that are not strictly necessary, for example for statistics, we will ask you first. You will then get a real choice window where rejecting is just as easy as accepting. We will explain any changes here.
Our cookies and crumbs are strictly necessary for the features you use yourself (Section 25(2) No. 2 of the German Telecommunications Digital Services Data Protection Act, TDDDG). Everything else is in our Privacy Policy.
