Privacy Policy

Last updated: 2026-04-24. Replace with jurisdiction-specific language before public launch — P5 task. Consult a lawyer for GDPR / CCPA specifics.

Data we collect

• Account info (if you sign up): email, hashed auth identifier (Clerk user id). We do not store passwords — authentication is handled by Clerk.
• Usage events: timestamp, discipline / level chosen, input character count, number of LLM calls, before/after AI score, semantic similarity. Used for billing, quota, and abuse detection.
• Payment info (if you subscribe): handled by Stripe. We receive a Stripe customer id and subscription status; we never see your full card number.
• Analytics: anonymous page views via PostHog when enabled. You can opt out via a browser "Do Not Track" header; we honor it.

What we do NOT store

• The full text you submit for rewriting is not retained after the request completes. It is forwarded to the language model and detector APIs for processing and then discarded.
• Your input text is not used to train any model.

Third-party processors

• Anthropic (language model) — sees your input text during processing; governed by Anthropic's Privacy Policy.
• GPTZero / ZeroGPT (AI detection) — sees your input text during scoring; governed by their respective policies.
• Clerk (authentication) — sees your email and login activity.
• Stripe (payments) — sees your payment method and billing address.
• Fly.io / Vercel (hosting) — sees request metadata (IP, user agent) for operational purposes.
