You must be at least 18 years old and capable of forming a binding contract to use the Service. By using BuildCrux, you represent that you meet these requirements. If you are using the Service on behalf of a business, you represent that you have the authority to bind that entity to these Terms.
New accounts pay the chosen plan's price at signup and receive full access immediately. If you cancel within thirty (30) days of initial purchase, you may request a full refund by emailing support@buildcrux.com. After the 30-day window, subscriptions renew automatically and refunds are not available except as required by law.
You may upgrade or downgrade your plan at any time from your dashboard. Upgrades take effect immediately and are prorated for the remainder of the billing cycle. Downgrades take effect at the start of the next billing cycle. Feature access may change when you downgrade.
When your clients pay invoices through BuildCrux, a per-transaction processing fee applies. The rate depends on your subscription plan. These fees are separate from your subscription fee and are deducted from each transaction.
Each plan includes a monthly allocation of AI estimate credits. Credits are used when you generate AI-powered project estimates. Unused credits do not roll over to the next month. Additional credit packs may be purchased separately.

You may export your data (projects, invoices, expenses, mileage) in CSV format at any time from your dashboard. We are committed to ensuring you can always take your data with you.
When you use the AI estimate feature, your project descriptions and uploaded blueprints are sent to our AI provider for processing. This data is used solely to generate your estimate and is not used to train AI models. See our Privacy Policy for details.
