Privacy Policy

1. Who we are

LEW is a student-focused learning workspace that combines notes, study rooms, file storage, and AI-assisted study tools. A core design principle of LEW is that your files live in your own Google Drive — LEW stores references to those files, not the files themselves, except where processing is required to provide a feature you request.

2. Information we collect

We collect only what we need to run the Service:

• Google account information. When you sign in with Google, we receive your name, email address, and profile picture to create and identify your account.
• Google Drive content you choose to use. Using the drive.file scope, LEW can only access files it creates on your behalf or files you explicitly open with LEW — it cannot see the rest of your Google Drive. This is used to store your notes, uploads, and study materials in a dedicated LEW/ folder in your Drive.
• Google Calendar events. Using the calendar.events scope, LEW creates calendar events with Google Meet links when you schedule a class or study-room meeting. LEW creates these events; it does not read your broader calendar.
• Content you create in LEW. Notes, study-room messages, comments, and AI chat conversations you create are stored so the Service can function.
• Usage metadata. We record limited, non-content metadata — such as feature usage counts, AI token counts, estimated costs, timestamps, and sign-in events — to operate the Service, enforce usage limits, and understand aggregate reliability and demand. This metadata does not include the contents of your files, notes, scans, or chats.

3. How we use AI and OCR (important disclosure)

Some optional features send content to Google Cloud services to generate a result you requested:

• AI Study Tools & AI Assistant. When you run Summarize, Flashcards, or Quiz on a file, or attach a file to the AI Assistant, LEW sends the contents of that file to Google Vertex AI (Gemini) to generate the study material or answer.
• Scan to Note (OCR). When you scan an image, LEW may send that image to Google Cloud Vision to extract text.

This processing happens only when you actively invoke the feature. Google Cloud processes this data to return your result and, for these enterprise services, does not use it to train generalized AI/ML models. Generated study results (summaries, flashcards, quizzes) are cached and tied to your account so you can view them again without re-processing; this cache is only ever shown back to you and is deleted when you disconnect Google or delete your account.

4. Google API Services — Limited Use disclosure

LEW’s use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. Specifically, we do not use Google user data for advertising, we do not sell it, we do not transfer it to third parties except to provide or improve the user-facing feature you requested (or as required by law), and we do not allow humans to read it except with your explicit consent, for security purposes, to comply with applicable law, or where the data has been aggregated and anonymized.

5. How your data is stored and shared

We do not sell your personal data. We share data only with the infrastructure providers (sub-processors) needed to run LEW:

• Google Cloud — Drive/Calendar APIs, Vertex AI, and Cloud Vision (as described above).
• Supabase — our PostgreSQL database, which stores your account and the LEW-created content and metadata above.
• Vercel — application hosting.

Your Google OAuth tokens are stored so LEW can act on your behalf and are transmitted only over encrypted connections.

6. Data retention and deletion

You are in control of your data:

• Disconnect Google. From Settings → Account you can disconnect your Google account at any time. This revokes LEW’s access tokens and deletes cached AI results derived from your files.
• Delete your account. From Settings → Account you can permanently delete your LEW account and the data we store about you. Files that live in your own Google Drive remain in your Drive and are yours to keep or delete.
• You may also revoke LEW’s access directly from your Google Account permissions page.

7. Security

We use encrypted connections (HTTPS) and rely on the security controls of our infrastructure providers. No method of transmission or storage is 100% secure, but we work to protect your information and limit access to it. Because LEW is a beta, we recommend not storing highly sensitive information in it.

8. Children and students

LEW is intended for students and educators. If you are under the age required to consent to online services in your country, please use LEW only with the involvement of a parent, guardian, or educational institution. We do not knowingly collect more data than described in this policy.

9. Changes to this policy

We may update this Privacy Policy as the Service evolves out of beta. When we make material changes, we will update the “Last updated” date above and, where appropriate, notify you in the app.
