Registering with CATMA

In order to work actively with CATMA you need to create a password secured account that is associated with an active email address. CATMA offers two authentication options:

  • creation of a user account via Google’s authentication system. If you use this system, Google’s Privacy Policy will apply to your Google account. Google will share your email address and a unique identifier (user ID) with us, nothing else. CATMA does not share any information with Google, other than that which is technically required to facilitate the authentication process.
  • creation of a user account via CATMA’s own authentication system. If you use this system, your account data will be accessible to the CATMA system only. Note that we use Google reCAPTCHA (v3) to protect our systems from bots and spam.

Irrespective of the authentication system chosen, all your account details are stored for internal authentication purposes only – CATMA does not pass on your personal data to any third party whatsoever. However, please note that any texts/corpora and/or tagsets uploaded to CATMA, as well as any meta data generated with the CATMA web application, is automatically linked to your user account. This is necessary to allow persistent access during a work session and between work sessions, and to enable collaboration in text analysis and annotation with CATMA.

Sharing data with others

When you use the “sharing” option in CATMA, either actively (i.e., you “share” your resources with others or invite them into a project) or passively (i.e., you accept somebody else’s invitation to access resources or join a project), your user identity (username and/or email address) may be made visible / displayed to all users or members of the project involved.

In addition, the contents of – and meta data associated with – the corresponding resources/project may be made visible to / editable by others (according to the roles and permissions which you assign, if applicable).

Be aware that someone with whom you have shared resources may be able to further share such resources without your knowledge or explicit approval.

Allowing other systems/tools to access your data

When you use the “Personal Access Token” feature in CATMA, and you give a token to another system/tool, you are providing them with an authentication mechanism that allows them to act on your behalf and access any and all information that you yourself can access, as well as perform any action that you yourself can perform, in accordance with the so-called scope of the token and the roles and permissions granted to you for specific resources.

Tokens created through the CATMA interface have a scope of “read_api” by default, meaning that such tokens can be used to retrieve, but not modify, any information to which your user account has access (projects and their associated resources and meta data, as well as corresponding user identities).

We have no control over data once it has been retrieved by other systems/tools. Therefore, when using this feature, you should carefully consider the potential impact on your own privacy and that of others.

Exporting data

CATMA provides multiple ways through which you can export data from the system and download it to your own computer. This includes the contents of – and meta data associated with – resources/projects, as well as corresponding user identities.

We have no control over data once it leaves our systems. Therefore, when using this feature, you should carefully consider the potential impact on your own privacy and that of others, and you should take appropriate action to protect such data from unauthorized access.

Log files and cookies

CATMA uses log files and internal cookies to enable certain features of the application. Log files are a means of documenting certain events that occur during a web-session. Cookies are small pieces of textual information relating to a user and their behavior on a website that are exchanged between the website and the user’s web browser. By “internal cookies” we mean cookies that are generated and used by CATMA internally without sharing any information with third parties. The information collected by log files and internal cookies includes internet protocol (IP) addresses and behavioral data. These are used to enable some of the core features of the CATMA application, such as saving annotations on texts or linking resources to specific user profiles.

CATMA reserves the right to post-process and analyze as training data for machine learning purposes any data and meta data contributed or generated by a user. Any user generated data / meta data used for these purposes will be processed strictly in anonymized format only and will not be used to profile individual users under any circumstances.

The developers of CATMA gather data from the site about which tools are invoked and with what parameters (IP addresses are logged to detect and fix bugs and other unwanted behavior). In addition, locally logged data helps the development team to debug and improve the tools, as well as to understand how researchers are using them. CATMA guarantees that any such data is strictly used in anonymous and aggregate form only.

You can choose to disable cookies through your individual browser options. However, please be aware that some of the core features of the CATMA application might not work when cookies are disabled. More detailed information about cookie management with specific web browsers can be found at the browsers’ respective websites.

Children’s Information

Another one of our priorities is adding protection for children while using the internet. We encourage parents and guardians to observe, participate in, and/or monitor and guide their children’s online activity.

CATMA does not knowingly collect any Personal Identifiable Information from children under the age of 13. If you think that your child provided this kind of information on our website or application, we strongly encourage you to Contact us immediately and we will do our best to promptly remove such information from our records.

This policy is not applicable to any information collected offline or via channels other than this website or our application.
