These are the Official Rules that govern how the WhenHub Hackathon (the "Hackathon") operates. In these rules, "we," "our," and "us" refer to CalendarTree, Inc. operating as "WhenHub." “You” and “Yourself” refer to an eligible entrant.


The intent and spirit of the Hackathon is to showcase the skills and creativity of coders and designers. All Entries must meet the following general standards:

- All Entry materials must be presented and/or submitted in the English language.

- The content of your Entry and any supporting materials must be acceptable for all viewing audiences. We will automatically disqualify any entrant that submits any Entry or supporting materials that contain text, sound or images that we, in our sole opinion and for any reason, find vulgar, offensive, or inappropriate for public viewing, or that presents us in a negative light.

By submitting an entry in this Hackathon, you confirm that, to the best of your knowledge:

Your Entry meets the requirements set forth above; and

The entirety of the entry is your/your team’s original work.

You/your teams have obtained any and all consents, approvals, or licenses required for you to submit your Entry.

Important note about copyright: Your team’s entire Entry must only include material (including source code—both open source and third party sourced, user interface, or media) that you own or that you have permission from the copyright/trademark owner to use. Your team’s Entry may not include copyrighted materials (such as source code, user interface, or media) unless you own or have permission to use the materials. Your team’s entry will be disqualified if copyrighted materials are a part of your Entry without appropriate licensing or permissions.

We reserve the right to disqualify or reject any Entry that we, in our sole and absolute discretion, determine does not meet the above criteria.

If we do not receive a sufficient number of Entries meeting the entry requirements, we may, at our discretion, select fewer than the designated number of winners. The decisions of the judges are final and binding in all matters related to the Challenge.
