Data protection policy

The online learning system bettermarks is owned and managed by bettermarks GmbH, Skalitzer Str. 85-86, 10997 Berlin (“bettermarks” or “we”).


It is very important to us to handle all our users’ personal data with the utmost reliability and security. In as far as we collect, process or use personal data in the course of providing our services, this transpires within the remit of the corresponding data protection legislation.


The following data protection policy serves to make as transparent as possible exactly which user data we save and for what purposes we use this data in each case.


(1) What data does bettermarks use?


Customer Data


You can visit our basic services without sharing any personal data with us. When you decide to work with our online learning system actively, we collect the following data from you:


As a student: Username, password and a valid e-mail address.


As a teacher: Password, title, first and last names, a valid e-mail address, the type of school and its address.


Learning Progress Data


While you use our online learning system, bettermarks collects certain data (so-called “learning progress data”), in order to guide you to appropriate exercises and to show you your progress. The learning progress data are only visible in the user’s account. When used in a school context such as homework and exercise series, the data are visible to the user and the user’s teacher(s). We will never share learning progress data with a third party.


The learning progress data include among other things the number of completed exercise series and exercises, the status of work in progress, the time taken for each task and the number of error-free and incorrectly completed exercise series and exercises.


(2) Cookies


You must accept cookies for bettermarks in your browser for bettermarks to function properly. The reason for this is that your Internet browser saves small packets of data (“cookies”) on your computer that contain information about your visit to our website. Most browsers are set to accept cookies as their standard setting. If you would like your browser to reject cookies automatically or to ask your permission before accepting them, you can change this setting. Rejecting these cookies can however mean that not all of our services function without disruption. bettermarks installs cookies permanently, based on each usage session.


How does Google use cookies for conversion tracking?

Google uses cookies so that companies (such as bettermarks) who pay Google for connecting advertisements can determine how many people who click on the advertisements subsequently purchase corresponding products. The cookie for conversion tracking is only saved in your browser when you click on a Google advertisement that has been selected by the advertised company (such as bettermarks) for conversion tracking. These cookies expire after 30 days and retain no information that can identify you personally. If you visit certain pages on the company’s website (such as that of bettermarks) and the cookie has not yet expired, both Google and the company (such as bettermarks) can recognize that you have clicked on the the advertisement and have been directed to this page. Every user receives a different cookie. This means that cookies cannot be tracked through the website of the company (such as bettermarks). If you would like to deactivate conversion tracking cookies, you can set up your browser to block cookies from the domain “”.


(3) Web Analysis with Google Analytics


bettermarks uses Google Analytics, a web analysis service provided by Google Inc. (“Google”). Google Analytics uses so-called “cookies”, text data that are saved on your computer and that enable an analysis of your bettermarks usage. Information collected through the cookie about your usage of this website is usually transferred to a Google server in the USA and saved there. Because bettermarks has activated IP anonymization on this website, Google truncates your IP address prior to saving it if you are in a member state of the European Union or another state that is a party to the Agreement on the European Economic Area. IP Addresses are only transferred to a Google server in the USA and then subsequently truncated in exceptional cases. On behalf of bettermarks, Google uses this information to evaluate your usage of the bettermarks website in order to create reports about website activity and to provide bettermarks with further services related to the usage of the bettermarks website and the Internet. The IP address transferred by your browser for Google Analytics is not combined with other data from Google. You can prevent your browser from saving cookies by changing its settings; however, we remind you that in this case you may not be able to use the full functionality of the bettermarks website and services. Another way to prevent Google from acquiring the data collected through the cookie that pertains to your usage of bettermarks (including your IP address) is by downloading and installing the following browser plugin:


You can find more information about this at and at (general information on Google Analytics and data protection). We would like to inform you that bettermarks has extended its Google Analytics Code with the Code “gat._anonymizeIp();”, in order to ensure that collected IP addresses are anonymous (so-called “IP-Masking”).


(4) No Unjustified Sharing of Data with Third Parties


bettermarks handles any personal data that you transfer with the utmost care. We will share data with third parties if and only if this is absolutely necessary for implementing and processing contractual obligations (such as for sending activation codes or for getting into contact with you should problems arise), or if you have given us your express permission or if this is allowed under applicable statutory provisions.
