Privacy Policy

Overview

BuildStax is in early preview. We collect the minimum data needed to operate the service and improve it. This policy explains what we collect, why, and how long we keep it.

What we collect

• Account info — email address when you join the waitlist or create an account.
• Usage data — task descriptions, model calls, and execution metadata. We use this to debug issues and improve routing.
• Repository data — file contents and diffs from repos you connect. This is processed in memory to complete your tasks and is not used to train models.
• Billing data — payment method and billing address, processed by our payment provider. We do not store full card numbers.

How we use your data

• To execute your coding tasks and return results.
• To debug, troubleshoot, and improve the product.
• To send service notifications (security alerts, breaking changes).
• To process payments and manage your subscription.

What we don't do

• We do not use your code to train AI models.
• We do not sell your data to third parties.
• We do not share your code with other users.

Data retention

Task execution data is retained for 30 days for debugging, then permanently deleted. Account data is retained until you request deletion. Email [email protected] to request data deletion.

Third-party processors

We use the following third-party services to operate BuildStax:

• AI model providers — Anthropic, OpenAI, Google, DeepSeek, and others. Your task data is sent to these providers for inference and returned. Each provider has their own data policies.
• Payment processor — Stripe for billing.
• Cloud infrastructure — hosting and compute providers.
