This page is maintained by Blanca's IT Professional SL to answer common security, privacy and trust questions about Blanca's Builder.
This page is app-owned editable content. It is not an independent audit or certification.
Security is a shared responsibility between Blanca's IT Professional SL, the platforms we run on (Cloudflare, Supabase) and you as the account owner.
Hosting
The frontend and server functions run on Cloudflare Workers and Pages. Static assets are cached at every Cloudflare edge location.
Database and auth
Application state lives in a Supabase PostgreSQL project in the EU. Authentication, session management and storage are provided by Supabase Auth and Supabase Storage.
AI gateway
AI requests are routed either through the Lovable AI Gateway (managed mode) or directly to your chosen provider in BYOK mode. We do not proxy provider responses through any third party we control.
Transactional email (auth, billing, project events) is sent through Resend with a verified custom domain.
DNS and TLS
DNS is operated by Cloudflare. TLS certificates are issued and renewed automatically; the canonical product domain is https://blancasbuilder.com.
