How MailOS works in Gmail
We analyze your emails to provide insights and organization, but your emails stay in Gmail. We only store statistics and insights.
Data Flow
What we receive from Gmail
- •Email metadata (sender, subject, timestamp)
- •Email content for analysis only
- •Labels and categories you've created
- •Read/unread status
What we store in our database
- •Email statistics (count, sender patterns)
- •AI classification tags and insights
- •Your custom groups and rules
- •Digest preferences and settings
What we NEVER store
✗ Your actual emails or full content
✗ Email attachments
✗ Passwords or credentials
✗ Any personally identifiable information
How the Integration Works
Read-Only Gmail Access
You authorize MailOS with read-only access to Gmail via OAuth. We can only read your emails, never modify, delete, or send them.
Real-Time Analysis
When you sync, we analyze your emails using AI to classify them by category, importance, and relevance. The analysis happens securely in our servers.
Dashboard Insights
The MailOS dashboard displays statistics, insights, and automated categories based on the analysis. The actual emails remain in Gmail.
Daily Digest Emails
We send you one daily email summarizing the insights and important messages. You can act on them directly in Gmail.
Why This Approach
Maximum Privacy
Your emails stay in Gmail where you expect them. We only process and store insights, not the actual content.
