Security

QA Note prioritizes customer data protection. We maintain industry-standard security practices and comply with GDPR standards.

• PIPA 2025: Compliance with key provisions
• GDPR: EU General Data Protection Regulation compliance
• ICT Network Act: Communication privacy and spam prevention
• Cloud Computing Act: User data protection and portability
• Public privacy policy
• Cookie consent management

• In transit: TLS 1.2+ (HTTPS enforced, HSTS preload)
• At rest: Infrastructure-level AES-256 encryption (database and file storage)
• Passwords: argon2id hashing (OWASP-recommended parameters)
• Tokens: Session tokens stored as SHA-256 hashes; external integration tokens (GitHub, Slack, etc.) encrypted with AES-256-GCM

• Hosting: Vercel (AWS-based, SOC 2 certified)
• Database: Supabase (AWS, SOC 2 certified)
• File storage: Cloudflare R2 (SOC 2 · ISO 27001 certified)

All infrastructure providers hold industry-standard security certifications.

• RBAC (Role-Based Access Control): Organization (Owner, Admin, Member) · Project (Admin, Member, Viewer)
• Principle of least privilege applied
• Independent permissions per project
• Invitation-based member onboarding

• Customer data is entirely owned by the customer
• Data is never sold or shared with third parties
• All data permanently deleted 30 days after account deletion (including R2 files)

• Pattern-based automatic sensitive data filtering in network requests
• Auto-masking of auth headers, API keys, tokens, and session IDs
• Removal of sensitive fields from URL parameters and request/response bodies (pattern-based — non-standard fields can be controlled via capture settings)

• Supabase managed automatic database backups
• Weekly automated storage–database consistency checks
• Automatic cleanup per data retention policy (deletion evidence recorded in audit logs)

• Security audit logging (failed logins, rate limit blocks, permission changes, account deletions, data deletion evidence, etc.)
• Real-time security alerts to the operations team on risky events
• Continuous monitoring of abuse signals such as signup and storage spikes

• Security headers on every page (CSP, HSTS preload, clickjacking protection)
• Tiered rate limiting on login, signup, email sending, uploads, and AI calls
• API input schema validation (Zod), open redirect and SSRF protection

• OAuth 2.0 standard (GitHub, Google)
• Slack integration: OAuth V2 authentication
• HMAC signature verification on all inbound webhooks (GitHub, payments, email)
• Strict CORS policy

• Payment processing: PortOne (PCI DSS Level 1 certified)
• Card information is never stored directly
• All payment communications encrypted

• No training: User data is never used to train our own or third-party AI models
• Minimal transfer: Only minimal metadata is sent when using AI features
• No retention: AI providers do not use API inputs for training and purge them after short-term retention for abuse monitoring
• Injection defense: The AI auto-fix pipeline isolates external inputs in fenced blocks and warns on sensitive file changes
