Privacy Policy

Last updated: March 2026

What We Collect

When you create an account, we collect your email address and (optionally) your name and profile photo via Clerk, our identity provider. When you start a paid trial we hand off to Stripe to collect a payment method; Stripe stores the card details, not us. Inside the app we store your manuscripts, snapshots, and AI conversation history so they can sync across your devices.

How We Use Your Data

Your email is used to send you transactional messages (sign-in links, receipts, important account notices) and the occasional product update you can opt out of. Your manuscript content is used only to power the features you invoke — chat, coaching, authoring, search — and is never used to train any LLM. We do not sell, share, or rent your data to third parties.

Data Storage

Account data lives in Clerk. Subscription and payment data live in Stripe. Manuscripts and AI usage telemetry live in a managed PostgreSQL database we operate. We use industry-standard security practices and encrypted transport everywhere.

Your Rights

You can request deletion of your data at any time by contacting us. You can unsubscribe from any email we send using the unsubscribe link at the bottom of the email.

Analytics

We use Vercel Analytics and Speed Insights to understand how visitors use our website. These tools collect anonymous usage data and do not use cookies for tracking.
