Privacy Policy

Last updated: March 26, 2026

Zeno is built on a simple principle: your emails are yours. We process your email data in real time to power our features and do not store your email content on our servers.

1. Who We Are

Zeno ("we," "us," or "our") is an AI-powered email management service operated by Zeno. You can contact us at support@myzenobox.com.

2. Information We Collect

Account Information

When you create an account, we collect your name, email address, and password (stored securely via Supabase authentication).

Email Data (Gmail & Outlook)

When you connect your Gmail or Outlook account, we access your emails using Google and Microsoft's official OAuth2. This access is used solely to:

  • Display your emails within the Zeno interface
  • Analyze emails using AI to provide summaries, priorities, and suggested actions
  • Send emails on your behalf when you choose to do so

We do not store your email content on our servers. Emails are processed in memory in real time and immediately discarded. We do not use your email content to train AI models.

Usage Data

We collect basic usage data such as features used, session duration, and error logs to improve the service. This data is not linked to your email content.

Payment Information

Payments are processed by Stripe. We do not store your credit card information. Stripe's privacy policy applies to payment data.

Settings & Preferences

We store your app settings, folder structure, contact list, and preferences in our database to provide a consistent experience across sessions.

3. How We Use Your Information

  • To provide and improve the Zeno service
  • To authenticate your identity and manage your account
  • To process payments and manage your subscription
  • To send you service-related emails (account confirmation, billing receipts)
  • To respond to support requests

We do not sell your personal information. We do not use your data for advertising.

4. Google API & Gmail Data

Zeno's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Specifically:

  • We only request the minimum Gmail scopes necessary to operate the service
  • We do not share Gmail data with third parties except as necessary to operate the service
  • We do not use Gmail data for serving ads
  • We do not allow humans to read your Gmail data unless you explicitly request support and grant permission
  • We do not use Gmail data to train AI or ML models

5. Microsoft & Outlook Data

When you connect your Microsoft/Outlook account, we access your mail using Microsoft's official OAuth2. The same data handling principles apply — we do not store your email content and only use it to power Zeno's features within your session.

6. Data Sharing

We share your data only with the following trusted service providers, and only as necessary to operate Zeno:

  • Supabase — authentication and database
  • Stripe — payment processing
  • Anthropic — AI analysis of email content (processed in real time, not stored)
  • Vercel — hosting and infrastructure

We do not sell, rent, or share your personal information with any third party for marketing purposes.

7. Data Retention

We retain your account information and settings for as long as your account is active. Email content is never stored. If you delete your account, all your data is permanently deleted within 30 days.

8. Your Rights

You have the right to:

  • Access the personal data we hold about you
  • Request correction of inaccurate data
  • Request deletion of your account and data
  • Disconnect your Gmail or Outlook account at any time
  • Export your data

To exercise any of these rights, email us at support@myzenobox.com.

9. Security

We use industry-standard security measures including TLS encryption in transit, secure authentication via Supabase, and OAuth2 for email access. We never ask for or store your email password.

10. Children's Privacy

Zeno is not directed at children under 13. We do not knowingly collect personal information from children under 13.

11. Changes to This Policy

We may update this privacy policy from time to time. We will notify you of significant changes by email or by posting a notice in the app. Your continued use of Zeno after changes constitutes acceptance of the updated policy.

12. Contact Us

If you have questions about this privacy policy, please contact us at support@myzenobox.com.
