Frequently Asked Questions

“Do I need to download CATMA?”
You don’t. You just need a good internet connection.

“If I use my Google account to sign in, will Google have access to my data?”
All we use from Google is its authentication service. Your text and annotation data will remain purely private (if you don’t share them with other CATMA users). You can also create your own CATMA account—check our terms of use for more details on this.

“Which operating systems and browsers can I use?”
All common browsers (Chrome, Firefox, Safari, Edge etc.) can be used as well as Apple, Windows or Linux. For more details, check the technical specifications. So far, touch devices cannot be used for annotating your texts with CATMA.

“Is CATMA really for free?”
Yes! As a research project, the development of CATMA is funded (currently by the German Research Foundation as part of the research project forTEXT). Further development, maintenance and user support are offered by our team at the Universität Hamburg, Germany.

“Where do you save my uploaded data?”
The IT center of the Universität Hamburg provides a CATMA server, that is subject to very strict safety regulations. Located in Germany, CATMA data as well as privacy policy fall under European jurisdiction.

“What happens to my data if your server crashes?”
Don’t worry, we are at least as neurotic about this as you: in addition to the CATMA server in Hamburg, two full backups are saved twice a day on two different commercial providers. One of them keeps the backups for three days, the other one even for half a year. In addition, incremental backups are saved every five minutes. In other words: we have a triple safety net.

“Is it possible to save local copies of my data?”
Absolutely. Feel free to export text and annotation data to your own computer.

“Is the uploadable file size or the number of users that work collaboratively limited?”
Theoretically not. If a problem arises, contact us and we will help to fix it. However, CATMA is a tool that emulates traditional practices in the field of qualitative text studies (with a focus on literary studies), and thus is not a quantitative or statistical text mining environment for handling massive amounts of data in non-interactive batch mode.

“What if something goes wrong and I need help?”
That is part of our mission. Do not hesitate to mail us and we will get back to you as soon as possible.
