Eligibility and teams

• Participants must be [18+ / students / open to all] and registered before the deadline.
• Teams have 1 to 4 members. Each person can join only one team.
• Teams can change members until hacking starts, but not after.

Timing and originality

• All project work must happen during the official hacking window. Planning ideas, sketching, and setting up tools beforehand is fine; writing project code is not.
• You may use open-source libraries, public APIs, templates, and AI coding tools. Credit them in your submission.
• Projects submitted to another hackathon or built before the event aren't eligible.

Working with existing apps

• Your project must clearly upgrade a real, existing app. Building an unrelated new app doesn't qualify.
• Use only public APIs, official extension or plugin systems, or your own recreation of the screens you're changing.
• Don't hack into, scrape against the terms of, or disrupt any real service, and don't use real users' private data.
• Use the app's name to describe your project, but don't present it as official or imply the company endorses it.
• Teams keep ownership of what they build.
