Privacy Policy
Effective: April 2026 · Buildstack Lab
1. Overview
Buildstack Lab (“Buildstack,” “we,” “us”) develops AgentIC, an autonomous silicon compiler available as both a command-line tool and a web application. This Privacy Policy describes what information we collect, how we use it, and what rights you have regarding your data.
Our approach is simple: the CLI tool collects nothing. The web application collects only what is necessary to provide authentication and build history.
2. CLI Tool — What It Does Not Collect
The AgentIC command-line tool runs entirely on your machine. It does not collect, transmit, or phone home with:
- Your design specifications or architecture descriptions
- Your generated Verilog RTL, netlists, or GDSII layouts
- Your system information, IP address, or hardware fingerprints
- Usage telemetry or analytics of any kind
What the CLI does communicate externally:
| External Call | Data Sent | Destination |
|---|---|---|
| License validation | License key only | api.lemonsqueezy.com |
| LLM API calls | Your design prompts (using your own API key) | Your chosen LLM provider |
| PDK downloads | None (read-only fetch) | github.com, volare repositories |
3. Web Application — What We Collect
When you use the AgentIC web console at agentic.buildstack.live or buildstack.live:
- Email address — collected through Supabase Auth for account creation and login. We do not require a password when using Google OAuth.
- Build data — design names, natural language descriptions, and build status/results are stored to provide your build history and enable the Human-in-the-Loop pipeline.
- Payment information — processed entirely by Razorpay and Lemon Squeezy. We never receive, store, or have access to your credit card details.
We do not collect your generated RTL code, netlists, GDSII files, or API keys from the web application. Build artifacts are stored temporarily for download and then purged.
4. How We Use Your Data
- Authentication: Your email is used to create and secure your account.
- Build history: Your design names and build results are displayed in your personal dashboard.
- Service improvement: Aggregated, anonymized build metrics (e.g., pipeline stage success rates, average build times) may be used to improve the Software.
We do not sell, rent, trade, or share your personal data with third parties for their marketing purposes. We do not use your data to train AI models.
5. Third-Party Services
Our services rely on the following third-party providers. Each operates under its own privacy policy:
| Service | Purpose | Policy |
|---|---|---|
| Lemon Squeezy | License issuance & validation | Privacy Policy |
| Supabase | Authentication & database | Privacy Policy |
| Razorpay | Payment processing (web only) | Privacy Policy |
| LLM Providers | AI-powered RTL generation | Data sent using your own API key; see your provider's policy |
6. Data Storage & Security
CLI tool: All data — credentials, cache, design files, and build artifacts — is stored locally on your machine under ~/.agentic/. Buildstack has no access to this directory.
Web application: User accounts and build data are stored in a Supabase-managed PostgreSQL database with encryption at rest. We employ industry-standard security practices including TLS encryption for all data in transit.
No method of electronic storage or transmission is 100% secure. While we strive to protect your data, we cannot guarantee absolute security.
8. Your Rights
You have the right to:
- Access: Request a copy of your personal data stored in the web application.
- Deletion: Request deletion of your web application account and associated data. CLI users can delete all local data by removing the
~/.agentic/directory. - Correction: Update your account email through the web application.
- Portability: Export your build history in machine-readable format.
To exercise any of these rights, contact us at contactme@buildstack.live. We respond within 30 days.
9. Data Retention
Web application account data is retained for the lifetime of your account. Upon account deletion, your personal data is permanently removed within 30 days. Anonymized build metrics may be retained indefinitely for service improvement purposes.
10. Changes to This Policy
We may update this Privacy Policy from time to time. Material changes will be communicated via our website and, for web application users, via the email address associated with your account. Continued use of the Software after changes take effect constitutes acceptance of the revised policy.
