This policy explains what Tadorimichi collects and how we use it.
1. What we collect
Without login (default): Your SRS progress, settings, and onboarding state are stored in your browser's localStorage. We do not receive this data.
With login (future): Email, display name, login provider (Google / email magic link). Progress data synced to our server.
Automatic: Basic request logs (IP, user agent, URL) for operational purposes, retained no longer than 30 days.
2. Why we collect it
- Deliver the service (show your progress, sync across devices)
- Prevent abuse (rate limiting, security)
- Understand aggregate usage (no personal identifiers in analytics)
3. Third parties
- Cloudflare — hosting, CDN, DDoS protection. Data may transit Cloudflare servers globally.
- Stripe (if you subscribe to Pro) — payment processing. We do not store card numbers.
- Anthropic (for AI features) — prompts are sent to Anthropic's API. We do not send personally identifying information alongside prompts.
4. Your rights
