How does Inbox Ninja keep my emails private?

Inbox Ninja runs locally on your Mac. Your emails never leave your device - only the specific content you're working with is processed. OAuth connection to Gmail can be revoked anytime.

Will replies sound like me?

Yes. Inbox Ninja learns your communication style from past emails. Draft replies match your tone, formality level, and typical response patterns.

Does it work with Google Workspace?

Yes. Works with personal Gmail and Google Workspace accounts. Same OAuth flow, same privacy guarantees.

How is this different from Gmail's smart compose?

Gmail suggests sentence completions. Inbox Ninja writes full contextual replies, summarizes long threads, and triages your entire inbox to surface what matters. It's the difference between autocomplete and an assistant.

Privacy Policy

Last updated: February 7, 2025

Overview

Inbox Ninja is an AI-powered email assistant that runs on Rush, the macOS agent platform. We take your privacy seriously. Your email data is processed locally and on-demand only when you explicitly request it.

How Gmail Access Works

Inbox Ninja connects to your Gmail through OAuth 2.0 authentication:

We never see or store your Gmail password
You grant specific permissions through Google's secure OAuth flow
You can revoke access at any time from your Google Account settings
OAuth tokens are stored securely in your macOS Keychain

What We Access

Inbox Ninja only fetches email data when you explicitly ask it to perform a task:

Triaging your inbox to surface important emails
Summarizing email threads
Drafting replies that match your writing style
Checking your calendar for scheduling context

No background syncing. We do not continuously monitor or index your inbox. Data is fetched on-demand per your request.

Data Storage

No email content on our servers. Email data is processed in-session and not persisted beyond fulfilling your request.
Session history (your conversation with the agent) is stored locally on your Mac in ~/.rush/sessions/.
OAuth tokens are stored in your macOS Keychain, not in plain text files.

Third-Party Services

Inbox Ninja uses the following services to process your requests:

Anthropic Claude - AI processing for understanding emails, generating summaries, and drafting replies. Email content sent to Claude is subject to Anthropic's privacy policy. Anthropic does not use API inputs for training.
Google APIs - Gmail and Calendar access through secure OAuth 2.0.

What We Don't Do

We do not train AI models on your email content
We do not sell or share your data with third parties
We do not store copies of your emails on our servers
We do not run background processes that continuously access your inbox

Your Control

You have full control over your data:

Revoke Gmail access anytime from Google Account permissions
Delete session history from the Rush app or by removing files from ~/.rush/sessions/
Request deletion of any data by contacting us

Security

All data transmission is encrypted using industry-standard TLS. OAuth tokens are stored in your macOS Keychain, which provides hardware-level encryption on supported devices.

Changes

We may update this privacy policy. Changes will be posted here with an updated date.
