Privacy Policy
SiliFlow was created with a fundamental engineering principle: your hardware intellectual property belongs entirely to you. SiliFlow Studio operates as a local-first desktop application that executes simulations and stores netlists strictly on your machine.
Your RTL and waveforms never leave your computer.
Unlike web-based compilers or cloud CAD platforms that upload your HDL sources to remote cloud servers, SiliFlow Studio is a standalone desktop application.
- ✓Zero Hardware Telemetry: SiliFlow never uploads, reads, analyzes, or stores your Verilog, SystemVerilog, VCD/FST waveforms, gate netlists, or GDSII layout files.
- ✓Local Compilers: Simulation and elaboration (using bundled open-source Icarus Verilog and GTKWave engines) run natively on your machine's CPU without external network calls.
- ✓Air-Gapped Friendly: SiliFlow Studio does not require continuous internet access or remote license verification daemons to function.
Minimal, transparent web data collection.
A. Anonymous Server Logs
When you visit https://siliflow.in, our hosting provider (Vercel) automatically logs standard, non-identifying HTTP request metadata (such as IP address, browser type, referral URL, and timestamp). These logs are utilized solely for server uptime monitoring and security.
B. Cookies and Session Storage
We do not use advertising cookies, behavioral tracking beacons, or data-broker pixels. When you sign in via /login or /signup, strictly necessary browser storage keeps your session active. See our Cookie Policy for the full list of storage keys.
C. Direct Communications
If you email us or submit an inquiry via our contact page, we collect only the information you voluntarily provide (such as your name and email address) strictly to reply to your question.
Third-party services.
We rely on reputable infrastructure providers to distribute software builds and host our public documentation:
- Vercel:Hosts the marketing website and technical documentation with edge SSL encryption and cookie-free analytics.
- Supabase:Provides Postgres authentication and optional roadmap progress storage under strict Row-Level Security (zero RTL stored).
- Resend:Delivers transactional signup OTP verification emails and website contact form inquiries.
- GitHub:Hosts our open-source project repositories, desktop releases, and public issue trackers.
User rights & compliance.
Depending on your jurisdiction (such as GDPR in Europe or CCPA in California), you have rights regarding your personal data:
- Right to request access to any personal correspondence we hold.
- Right to request correction or complete deletion of your contact records.
- Right to opt out of any future informational email updates at any time.
