Medium.

Respect for privacy Does the tool require registration? Who can see my data? Can I remain anonymous?
High (?). Word Search Labs collects information posted or sent on the site, credit card data, web log data, cookies, and data from third parties. Yet, providing this data is optional since the tool does not request personal information from users unless they decide to sign up or log in. In such cases, data is used to provide/improve services, combat fraud/abuse, and is not shared for marketing purposes. This is stored for business purposes and as required by law in the United States. Word Search Labs’ privacy policy lacks important information on security, among others. Word Search Labs does not state compliance with the GDPR. See more here.
Saving work for future use Possiblity to save your or others´ work for reuse/reproduction
No.
Tailorability (If so, how?) Possibility of the tool to be used for a range of different activities (e.g. to what extent you can organize a project assignment with a central activity based on this tool)
