Privacy Policy
This policy covers Kyra, our desktop application, and Kyra Capture, our Chrome extension. The short version: your messages are processed and stored on your own computer. We never sell your data, never show you ads, and never use your messages for anything other than the features described here.
What Kyra Capture (the Chrome extension) does
With your permission, the extension reads Gmail messages in the accounts you are signed into in your browser. It does this in two ways: it checks Gmail's unread-message feed for accounts signed into your browser session, and it reads message content on mail.google.com pages you have open. It uses this to identify messages that look like they need a reply.
Captured messages are handed directly to the Kyra application running on the same computer, using Chrome's native messaging. The extension does not transmit your data off your device. It has no servers of its own and sends nothing to us or to third parties.
When you approve a reply inside Kyra, the extension opens the Gmail thread in your browser and enters the reply there on your behalf, exactly as if you had typed it. Replies are only sent when you explicitly approve them.
What the Kyra desktop application does
Kyra stores the messages it captures in a local database on your computer. Filtering and prioritization run on a local AI model on your machine. If you grant macOS Full Disk Access, Kyra also reads your WhatsApp Desktop message database locally to surface WhatsApp messages that need a reply; that data likewise stays on your device.
The one case where data leaves your device
To draft reply suggestions, Kyra sends short excerpts of a message to our reply service over an encrypted connection. Our service forwards them to a large-language-model provider to generate the draft and returns the result to your device. We use this content only to generate your reply. We keep operational logs (for billing and abuse prevention) for at most 30 days; we do not build profiles from your messages, and we do not permit this content to be sold or used for advertising. If the reply service is unreachable or you opt out, drafting falls back to the local model and nothing leaves your device.
Browser permissions, explained
- Access to mail.google.com: to read messages that may need a reply and to enter replies you approve.
- Native messaging: to hand captured messages to the Kyra application on your computer.
- Storage: to remember which messages were already captured, so nothing is processed twice.
- Alarms: to check for new messages periodically.
Your control
Everything lives on your device. Uninstalling the extension stops all capture. Uninstalling Kyra and deleting its data folder (Library/Application Support/Kyra) removes every stored message. You can ask us to revoke your reply-service access token at any time.
What we never do
- Sell or rent your data, or share it for advertising.
- Use your messages for purposes unrelated to the features above.
- Allow humans to read your messages, except with your explicit consent when helping you debug a problem.
Changes and contact
If we change this policy, we will update this page and the effective date above. Questions or requests: sahil@interface4agi.com.
