SecondBrain ("we", "our", or "the app") is an AI-powered note-taking assistant for iOS. Your privacy matters to us. This policy explains what data we collect, how we use it, and the choices you have.

1. Data We Collect

We collect only the data necessary to provide the app's features:

• Account information — email address and display name, collected during sign-up via Google, Apple, or email/password authentication.
• User-generated content — notes, folders, summaries, and calendar events you create within the app.
• Voice recordings — audio you record is processed in real time to create notes. Recordings are sent to Google Gemini for transcription and are not permanently stored on our servers.
• Timezone — used to correctly schedule calendar events.

2. How We Use Your Data

• AI processing — your text and audio are sent to Google Gemini to generate notes, summaries, and calendar events. Your data is processed in real time and is not used to train AI models.
• Storage — your notes, folders, and calendar events are stored in a Supabase PostgreSQL database, isolated by user account via Row-Level Security (RLS).
• Authentication — we use Supabase Auth with Google OAuth and Apple Sign-In to securely manage your account.

3. Third-Party Services

We rely on the following services to operate the app:

• Google Gemini — AI processing of voice and text.
• Supabase — database, authentication, and backend functions.
• Google OAuth / Apple Sign-In — secure authentication.

Each service processes data in accordance with its own privacy policy.

4. What We Do NOT Collect

• We do not track you across apps or websites.
• We do not use analytics or advertising SDKs.
• We do not sell, share, or monetize your data in any way.

5. Data Security

All data is transmitted over HTTPS. Database access is enforced by Row-Level Security policies, meaning each user can only access their own data. Authentication tokens are managed securely by Supabase Auth.

6. Data Retention & Deletion

Your data is retained for as long as you maintain an active account. You may delete your entire account and all associated data at any time from within the app (Settings → Delete Account). Deletion is immediate and irreversible — all notes, folders, calendar events, and account information are permanently removed.

7. Children's Privacy

SecondBrain is not intended for children under the age of 13. We do not knowingly collect personal data from children.

8. Changes to This Policy

We may update this policy from time to time. Changes will be reflected on this page with an updated date. Continued use of the app constitutes acceptance of the revised policy.
