Privacy Policy

Last updated: February 2026

aInbox ("we", "us") is an email summarization service. We take your privacy seriously. This policy explains what happens when you forward an email to summary@ainbox.io.

What we process

When you forward an email, we receive:

Your email address (the sender/forwarder)
The email subject line
The email body content
Any inline forwarded message content

How we process it

Your email content is sent to OpenAI's GPT-4o-mini model to generate a summary. The summary is then sent back to you via Resend (our email delivery provider).

Processing happens in real-time. The entire pipeline typically completes within a few seconds.

What we store

We do not store your email content. Emails are processed in memory and discarded immediately after the summary is sent. We do not have a database. We do not retain email bodies, subjects, or summaries.

Temporary in-memory rate limiting tracks your email address and request count (reset every 24 hours and on server restart). No persistent storage.
