Respect for privacy Does the tool require registration? Who can see my data? Can I remain anonymous?
Medium. Biteable collects user data such as names, email addresses, payment information, cookies, and content created using their services, so it seems to collect more data than is strictly required for video creation. Biteable’s privacy policy shows an understanding of security concerns but it states sharing data with third parties for various purposes, including analytics and service improvement. It states compliance with GDPR and provides users based in the EU with control over their data through options to access, modify, or delete it. See more here.
Saving work for future use Possiblity to save your or others´ work for reuse/reproduction
Yes.
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)
