+# Pre-Release TODO
+
+Things YOU need to do before we can build the final release tiers. None of these can be automated.
+
+## Accounts & Services
+
+- [ ] **Hostinger VPS** — provision a KVM 2 (2 vCPU, 8GB RAM, ~$8.50/mo), Ubuntu 24.04, US East
+- [ ] **Point DNS** — log into your domain registrar, point deepcutsai.com nameservers to Cloudflare
+- [ ] **Cloudflare account** — free, add deepcutsai.com, set up DNS A record to Hostinger VPS IP
+- [ ] **Cloudflare email routing** — forward hello@deepcutsai.com to your personal inbox (free, 2 min setup)
+- [ ] **Resend account** — sign up at resend.com, verify deepcutsai.com domain, get API key (for password reset & welcome emails)
+- [ ] **Stripe account** — sign up, create a Product ("Vynl Premium" at $6.99/mo), get API keys + webhook secret + price ID
+- [ ] **Separate Anthropic account** — you have a key already but rotate it since you shared it in chat
+- [ ] **Last.fm API key** — free, instant at last.fm/api/account/create (for Last.fm import feature)
+
+## Legal (required for SaaS taking payments)
+
+- [ ] **Privacy Policy** — generate at termly.io (free), covers email, listening data, Stripe
+- [ ] **Terms of Service** — generate at termly.io, covers refund policy, acceptable use
+- [ ] **Business address** — Stripe requires one displayed on your site (can be a PO Box or registered agent)
+- [ ] **Decide on business entity** — sole proprietorship works to start, LLC for liability protection ($50-200)
+
+## Content & Branding
+
+- [ ] **Landing page copy** — write real marketing copy or tell me to generate it
+- [ ] **App Store description** — 1-2 paragraph description for sharing on social media
+- [ ] **Social accounts** — Twitter/X, maybe Instagram for @deepcutsai or @vynlmusic
+- [ ] **OG image** — a 1200x630 image for social sharing previews (or I can generate a placeholder)
+
+## Testing
+
+- [ ] **Test every feature end to end** — register, import playlist, discover, save, share, all pages
+- [ ] **Test on mobile** — iPhone + Android, check all pages render properly
+- [ ] **Test payment flow** — Stripe test mode checkout → upgrade to Pro → manage subscription
+- [ ] **Get 3-5 beta testers** — real users giving honest feedback (you have 4 already!)
+- [ ] **Collect beta feedback** — what works, what's confusing, what's missing
+
+## Give Me When Ready
+
+Once you have these, give me:
+1. Hostinger VPS IP address
+2. Resend API key
+3. Stripe secret key, publishable key, price ID, webhook secret
+4. Last.fm API key
+5. Fresh Anthropic API key (rotate the one shared in chat)
+
+Then I'll build:
+- Production deployment to Hostinger
+- Password reset + welcome emails via Resend
+- Stripe payment flow (end to end)
+- Privacy/Terms pages
+- SEO meta tags + OG images
+- Final mobile responsive pass
+- Error tracking (Sentry)
