Frequently Asked Questions

Will I miss important emails?

No. Human threads always surface first in zen view. Newsletters are collapsed but still visible below. You can toggle to "Everything" mode anytime to see your full inbox.

What permissions do you need?

Lumo needs read access to Gmail to detect newsletters by list-unsubscribe headers, and local storage to save your preferences. We never send your email content to servers.

Does it work with Google Workspace?

Yes! Lumo works with any Gmail account, including Google Workspace (G Suite) accounts. Install the extension and it activates automatically.

How does unsubscribe work?

Lumo detects Gmail-safe unsubscribe links (RFC 8058 standard). One click sends the unsubscribe request. For suspicious emails, we recommend using Gmail's "report spam" instead.

Is my data safe?

Absolutely. All processing happens locally in your browser. We do not collect, store, or transmit your email content, sender lists, or reading behavior. Your data never leaves your device.

When will the Chrome Web Store version be available?

We're submitting to the Chrome Web Store soon. For now, you can load the extension manually (dev build). Join the waitlist to be notified when the official version launches.
