In plain English
Your writing is yours. It is never used to train AI models, sold, or shared for marketing.
We store what we need to run the product, encrypt all of it, and delete everything the moment you ask us to.
What we collect
We collect the information you provide directly: your email address, name, role, writing preferences, any source documents you upload, and the edits you make to drafts. We also collect basic usage data (pages visited, feature usage) to improve the Service.
How we use it
Your data is used exclusively to provide the Service to you: generating content in your voice, learning your preferences, and improving your experience. We do not sell, rent, or share your personal data with third parties for marketing purposes.
AI and your data
Your content is processed by third-party language models (via OpenRouter) to generate drafts. These providers operate under enterprise terms that explicitly prohibit using your data for model training. Your writing never becomes part of any model's training data.
Data storage and security
Your data is stored in Supabase (Postgres database). Row-Level Security enforces per-user isolation at the database engine level. All data is encrypted at rest (AES-256) and in transit (TLS 1.3).
Third-party services
We use: Supabase (authentication and database), Vercel (frontend hosting), Railway (backend hosting), OpenRouter (language model routing), Exa (research), Paddle (payment processing), Resend (transactional email), and Sentry (error monitoring). Each operates under their own privacy policies and enterprise-grade security standards.
Your rights
You can export or delete your data at any time. Account deletion is permanent and cascading: all personas, drafts, packs, and associated data are purged. To request deletion, use the option in Settings or email hello@quill-writer.com.
Changes
We may update this policy from time to time. Material changes will be communicated via email. Continued use after changes constitutes acceptance.
