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.
- Payment processors — if and when paid plans are introduced, we will use a third-party processor (e.g. Stripe) to handle payments. We do not store card numbers ourselves. The current product has no paid tier.
- Anthropic (for AI features) — prompts are sent to Anthropic's API. We do not send personally identifying information alongside prompts.
4. Your rights
- Access / export: Export your data as JSON from /me.
- Delete: Delete your account directly from /me, or contact us at the address below to request deletion.
- Correct: Update your email or display name from /me.
EEA / UK users: rights under GDPR. Mainland China users: we aim to follow PIPL requirements where applicable.
5. Children
Tadorimichi is not directed at children under 13. If you believe a child has provided us personal data, contact us for removal.
6. Changes
We will notify material changes via email or a site banner.
