Hi Patrick

Thanks for reaching out to Lucid Support. If you are a teacher or student using Lucid for classroom use please use your school issued email address to create a free Lucid account and then fill out this form to request a free educational upgrade. Once the form is submitted the upgrade may take up to one week to apply. The upgrade will be valid for two years.

Please see the Lucidchart EDU article for more details on our educational offerings. One thing I'd like to clarify is that with the free educational upgrade you are able to create an unlimited number of documents but only the three most recent will be editable.

If this information didn't answer your question please respond in this thread and we can help you further. Thank you and have a great school year!
