Privacy Policy

Last updated: April 23, 2026

1. Introduction

Dotto (“we”, “our”, or “us”) is committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data when you use our Service.

2. Information We Collect

We collect the following types of information:

  • Account information — your name and email address, provided via Google sign-in or email registration (managed by Clerk)
  • Lecture audio — audio is extracted from your video directly in your browser and sent to our servers for analysis. Raw audio is not permanently stored after processing is complete
  • Exam PDFs — documents you upload are stored securely and used to generate embeddings for relevance scoring
  • Usage data — information about how you use the Service (e.g., number of lectures processed, ratings given)

3. How We Use Your Information

We use your information to:

  • Provide and improve the Service
  • Analyze your lecture video to identify exam-relevant segments and guide you through the content
  • Score and color-code lecture moments based on your uploaded exam materials
  • Manage your account and subscription
  • Communicate with you about your account or the Service
  • Enforce our Terms of Service and prevent abuse

We do not sell your data, and we do not use your content to train AI models.

4. Third-Party Services

We work with the following third-party providers to deliver the Service:

  • Clerk — authentication and account management
  • OpenAI — AI transcription and language processing
  • Pinecone — vector database for exam question embeddings
  • Modal.com — cloud GPU infrastructure for processing
  • Vercel — web hosting and file storage (Vercel Blob)

Each provider has its own privacy policy. We only share the minimum data necessary for them to provide their services.

5. Data Retention

We retain your account data and analysis results (relevance scores, segment metadata) for as long as your account is active. Exam PDFs and their embeddings are retained until you delete them or close your account. Raw audio files are deleted after processing is complete and are never permanently stored. You may request deletion of your data at any time by contacting us.

6. Data Security

We implement industry-standard security measures to protect your data, including encrypted connections (HTTPS), access controls, and secure cloud infrastructure. However, no system is completely secure, and we cannot guarantee the absolute security of your information.

7. Your Rights

You have the right to:

  • Access the personal data we hold about you
  • Request correction of inaccurate data
  • Request deletion of your data
  • Object to or restrict processing of your data
  • Withdraw consent at any time (where processing is based on consent)

To exercise any of these rights, contact us at team@dotto.solutions.

8. Cookies

Dotto uses essential cookies for authentication and session management (via Clerk). We do not use advertising or tracking cookies. You can control cookie settings through your browser, but disabling essential cookies may prevent you from using the Service.

9. Children's Privacy

The Service is not directed to children under the age of 16. We do not knowingly collect personal information from children under 16. If you believe we have inadvertently collected such information, please contact us immediately.

10. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes by posting the new policy on this page with an updated date. Continued use of the Service after changes are posted constitutes your acceptance of the updated policy.

11. Governing Law

This Privacy Policy is governed by the laws of the State of Israel, including the Protection of Privacy Law, 5741-1981 and applicable regulations.
