Everyone's AI

Privacy Policy

Effective: May 21, 2026 (updates will be announced on this page).

1. Scope

This Privacy Policy applies to Everyone's AI (mdooai.com) and related services: Learn, Book reading, Community, Playground, paper reviews, the Chrome extension, and support pages. Some Learn chapters or features may be Premium (paid).

2. Information we collect

We may collect and use the following when you use our services. Authentication, hosting, and payments are handled by specialized providers subject to their own policies.

  • Account and authentication: email, display name, profile identifiers, etc., via Clerk or similar (we may not store passwords directly).
  • Usage and learning data: chapter progress, badges, Community posts/comments/uploads, curriculum (Book reading) data, AI coach questions and responses, etc.
  • Device and access: browser, IP, timestamps, cookies/sessions (service delivery, analytics, security, locale).
  • Payment and subscription: processed by Paddle, PayPal, or others; we do not store full card numbers. Subscription status, payment IDs, and receipts are used for Premium access, refunds, cancellation, and support.
  • Processors: some Community and curriculum data may be stored in Supabase or similar cloud databases; AI coach requests may send question context to AI APIs (e.g., Upstage).

The Chrome extension does not collect or transmit user data. It only opens https://mdooai.com/learn in a new tab when you click the icon.

3. How we use the information

We use data for authentication, Learn/Community/Book reading services, Premium subscription management, AI coach and search features, improvements and incident response, security and abuse prevention, legal compliance, and support.

4. Retention and deletion

We delete or anonymize personal data when purposes are met or legal retention periods end. Account deletion or erasure requests are handled per our procedures and processor policies.

5. Third parties and processors

We do not sell personal information. For operations we use processors such as Clerk (auth), Supabase (storage), Paddle/PayPal (payments), and AI API providers (learning coach). We may disclose information when required by law.

6. Policy changes

We update this page when the Privacy Policy changes. Material updates will state an effective date.
