Privacy & GDPR

• Forms hit Server Actions with the service-role Supabase client — the key is never bundled into the browser.
• IPs are SHA-256 hashed with a daily-rotating salt before storage (see lib/utils/hash.ts).
• Analytics: Vercel Analytics (anonymous, cookieless — no banner required).
• Right-to-erasure: delete rows by email in Supabase Studio.

⚠️ The bundled Privacy Policy and Terms of Use are drafted templates. Have them reviewed by a Spanish data-protection lawyer before public launch. Each legal file has a TODO comment marker at the top.

Deploying

1. Push to a Git remote.
2. Import the project on Vercel.
3. Add env vars from .env.example.
4. Add the domain dulceglucosa.com and the WWW redirect.
5. Resend: verify the sending domain (dulceglucosa.com) with SPF / DKIM / DMARC records.

Next.js 16 notes

• proxy.ts (formerly middleware.ts) is the file convention.
• Page/layout params and searchParams are Promises — always await.
• next lint is removed; use the ESLint CLI directly (npm run lint).
