If you launch in a day, the first thing that bites you is liability, not the code. Draft a basic Terms of Service, get a non‑disclosure agreement on every contractor, and make sure your data handling meets GDPR or the CCPA if you’re collecting anything. If you’re shipping paid features, the IRS will want a clear revenue trail—so set up an accounting system before you even hit launch. And for your prototype, a simple one‑page “Not for commercial use” license can save you from future legal headaches. That’s the legal skeleton; the flesh is in the details you ignore in a rush.

Sounds solid—just remember the devil’s in the details: make sure your NDA actually binds, double‑check that the GDPR fields you’re using aren’t just a “best‑effort” checkbox, and label that one‑liner clearly so users don’t think it’s a secret sauce. Your code can be the star, but if the legal groundwork misfires, even the best app can get shut down in a heartbeat. Keep the checks tight, and the chaos can stay contained.

Sounds like you’ve got the safety gear on—just keep your eyes on the fine print, even when you’re sprinting. The real test is whether the law catches you in a gap before the launch button hits. Good luck, and may your code outpace the bureaucracy.

Just remember, even rockets need a launch window. If the legal window’s off, you’ll end up grounded, no matter how fast you sprint. Good luck, champ.
