Privacy Policy

Last updated: August 29, 2026
Short version: Your drafts and profile live in your browser. Our servers keep only your account email, hashed credentials, and usage counts. We never sell data, never train AI on your emails, and one click wipes your local data.

1. Who we are

Quill, Inc. ("Quill," "we," "us") operates quillresearch.org, a tool that helps high school students draft personalized outreach emails to research labs. This policy explains what we collect, why, where it lives, and your rights over it. Contact: hello@quill.ink.

2. What lives only in your browser

The working product runs client-side. Your profile details (name, school, city, year, interests), your CV attachment, your drafts, and your send history live in your browser's local storage on your device. They are not uploaded to Quill servers as you type, and one click of "Reset all data" on your Profile page wipes them instantly.

3. What we store on our servers

We keep a deliberately small server-side footprint (hosted on Supabase, a US cloud database provider):

4. AI processing

When you click Generate, the relevant parts of your profile and the target researcher's public information are sent to Anthropic's Claude API through our server to produce your draft. Anthropic processes the request to generate the output and, under the API terms we operate on, does not use it to train models. We do not store the prompt or the draft server-side.

5. Payments

Pro subscriptions are processed by Stripe. Your card details go directly to Stripe; we never see or store them. We receive from Stripe only what we need to activate your plan (your email and subscription status).

6. What we never do

7. Children's privacy

Quill is intended for students aged 13 and older and is not directed at children under 13. We do not knowingly collect personal information from children under 13; if we learn we have, we will delete it. If you are a parent or guardian and believe a child under 13 has created an account, contact hello@quill.ink.

8. Your rights and choices

Depending on where you live (for example California or the EU), you may have additional statutory rights; we honor reasonable requests regardless of jurisdiction.

9. Security

Transport is HTTPS everywhere with HSTS; we ship a strict Content Security Policy, rate limiting on all API endpoints, and cryptographically random verification codes. See the Security page for details and how to report vulnerabilities.

10. Data retention

Server-side records are kept while your account is active and deleted on verified request. Verification codes expire and are purged automatically. Local-storage data persists until you clear it.

11. Changes

We will update this policy as the product evolves and change the date above. Material changes will be announced on the site. Continued use after changes take effect means you accept the updated policy.
