Privacy Policy

1. Who we are

ZenBrain (“ZenBrain”, “we”, “our”) is a browser extension and associated web services. Contact us at privacy@zenbrain.io.

2. What data we collect

The extension collects the following data locally on your device:

• Tab titles and URLs of tabs you have open
• Time each tab was opened and closed
• Focus duration per tab (tabs with <30 seconds of focus are excluded)

This data is stored in Chrome local storage. It is never transmitted automatically.

3. When data leaves your device

Data is only sent to our servers when you explicitly request a Recap. At that point, the tab titles and URLs from your session are sent to our AI provider to generate a plain-English summary. No background syncing occurs.

If you use the Notion or Google Drive export, your recap content is transmitted to those third-party services using the OAuth credentials you have granted.

4. What we never collect

• Page contents (articles, documents, emails)
• Form inputs, passwords, or search queries
• Incognito / private browsing activity
• Personal identifiers (we require no account to use the extension)

5. Analytics

The marketing site (zenbrain.io) uses Plausible Analytics, a privacy-focused, cookieless analytics tool that does not track individuals across sites or devices.

6. Data retention

Session data lives in your browser’s local storage. You can delete it at any time via the extension settings or by clearing Chrome storage. We retain recap summaries on our servers only if you request Notion/Drive export; deletion requests can be sent to privacy@zenbrain.io.

7. Third-party services

• AI recap provider — tab titles and URLs are sent on explicit user request. Data is not used to train models.
• Notion / Google Drive — export uses your personal OAuth token; your data is governed by those services’ privacy policies.

8. Your rights

You can request access to, correction of, or deletion of any personal data we hold by emailing privacy@zenbrain.io. We respond within 30 days.

9. Changes to this policy

We will update the “Last updated” date above when we make material changes and notify waitlist subscribers by email.
