Support the project

Kids and Novice lessons are free. Pro and Lifetime unlock higher tracks and additional tools. All plans have a daily AI allowance.

If the project is useful to you and you would like it to keep existing, voluntary support is the way. It funds the things that actually cost money: hosting, the Firebase tier, and the AI APIs that power the Mission Architect.

Use AI a lot? Upgrade to Pro

Pro includes all tracks, scenario tools, and 40 daily AI generations. Lifetime includes the same features with 15/day. Free accounts receive 3/day.

What support pays for

• Hosting, database, and domain costs (vary with usage)
• AI API calls (Gemini for the Mission Architect). The free 3-Architect-generations-per-day allowance for every signed-in user is included.
• Adding new lessons, replays, and missions
• Mobile + accessibility polish

Honest disclosure

Delta-V Academy is operated by BuildingRome Studio LLC, a US for-profit company. Contributions are voluntary gifts and are not tax-deductible. If a 501(c)(3) arm is set up later, tax-deductible donations would route through that entity instead; Delta-V Academy will say so explicitly when that happens.

Recurring sustainers can cancel any time from their account menu. There is no minimum commitment, no perks gate, and no content tier behind any of this. Support is a thank-you, not a transaction for access.

Other ways to help

• Share Delta-V Academy with a student, a teacher, a friend who is curious about space.
• Send a screenshot of something you learned to hello@deltavacademy.com. Real feedback is the highest-leverage gift.
• Spotted a bug? Let us know via the contact page. Bonus points for the lesson and step.
