Privacy Policy

Last updated: March 6, 2026

1. Introduction

Lumi ("Lumi", "we", "us", or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our AI-powered reminder service via WhatsApp and our web application.

2. Information We Collect

We collect information that you provide directly to us and information we obtain automatically:

  • Account information: Email, name, and WhatsApp phone number when you register
  • Message content: The messages you send to Lumi (reminder text, dates, and related instructions) to provide our service
  • Usage data: How you interact with our service, including API usage and feature usage
  • Device information: Browser type, IP address, and similar technical data

3. How We Use Your Information

We use the information we collect to:

  • Provide, maintain, and improve our reminder and notification services
  • Process your natural language requests and create reminders
  • Send you reminders and notifications at the times you specify
  • Authenticate your account and prevent fraud
  • Respond to your support requests and communicate with you
  • Analyze usage patterns to improve our AI and product experience
  • Comply with legal obligations

4. AI and Message Processing

Your messages are processed by AI models (including third-party services such as OpenAI) to understand your intent and create reminders. Message content may be temporarily stored for conversation context. We do not use your message content to train AI models for purposes unrelated to providing our service to you.

5. Data Sharing and Disclosure

We may share your information with:

  • Service providers: Twilio (WhatsApp), OpenAI (AI processing), Clerk (authentication), and other providers necessary to operate our service
  • Legal requirements: When required by law, court order, or government request
  • Business transfers: In connection with a merger, acquisition, or sale of assets

We do not sell your personal information to third parties.

6. Data Retention

We retain your reminder data and conversation history for as long as your account is active. Conversation history is typically kept for a limited period (e.g., 7 days) for context. You may request deletion of your data at any time by contacting us.

7. Data Security

We implement appropriate technical and organizational measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the internet is 100% secure.

8. Your Rights

Depending on your location, you may have the right to:

  • Access the personal data we hold about you
  • Request correction or deletion of your data
  • Object to or restrict certain processing
  • Data portability
  • Withdraw consent where processing is based on consent

To exercise these rights, please contact us. You may also manage your account and notification preferences through our settings.

9. Children's Privacy

Lumi is not intended for users under 13 years of age. We do not knowingly collect personal information from children under 13. If you believe we have collected such information, please contact us and we will delete it.

10. International Transfers

Your information may be transferred to and processed in countries other than your own. We ensure appropriate safeguards are in place for such transfers where required by law.

11. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of material changes by posting the updated policy on this page and updating the "Last updated" date. We encourage you to review this policy periodically.
