Connect Gmail

Automatically capture receipts from your Gmail inbox.

Connect your Gmail account to automatically capture receipts and invoices from your email. No manual forwarding required.

#How it works

Once connected, LUMA:

  1. Scans your inbox for emails that look like receipts and invoices
  2. Uses AI to identify transaction-related emails
  3. Extracts attachments and relevant data
  4. Sends them to your LUMA inbox for matching

The scanning happens automatically on a regular schedule.

#Connect Gmail

  1. Go to Inbox → Settings
  2. Click Connect Gmail
  3. Sign in to your Google account
  4. Review the permissions and click Allow

You'll be redirected back to LUMA once connected.

#What emails are scanned

#Emails we process

The AI looks for emails that are likely receipts or invoices:

  • Order confirmations: Amazon, Shopify stores, e-commerce purchases
  • Digital receipts: Uber, Lyft, Airbnb, travel bookings
  • Subscription receipts: SaaS tools, streaming services, subscriptions
  • Invoice emails: Bills, vendor invoices, payment confirmations
  • Bank notifications: Transaction alerts with receipt information

#Emails we ignore

The AI filters out non-receipt emails:

  • Marketing emails: Newsletters, promotions, sales announcements
  • Social notifications: LinkedIn, Twitter, Facebook updates
  • Personal emails: Messages from friends and family
  • Spam: Anything in your spam folder
  • General business emails: Meeting invites, project discussions

The AI is trained to distinguish between "someone sent me a receipt" and "someone sent me an email."

#What LUMA accesses

LUMA has read-only access to your Gmail:

PermissionWhat it allowsWhat we do
Read emailsView email contentScan for receipt-like patterns
Read attachmentsView email attachmentsExtract PDFs and images

#What we cannot do

  • Send emails from your account
  • Delete or modify emails
  • Access contacts or calendar
  • Read drafts

#Privacy and security

#Data handling

  • Selective processing: Only emails matching receipt patterns are processed
  • Secure storage: Extracted receipts are encrypted in your LUMA account
  • No training data: Your emails are not used to train AI models
  • Team isolation: Only your team can access your receipts

#What we store

  • Extracted receipt/invoice files (PDFs, images)
  • Extracted data (merchant, amount, date)
  • Email metadata for deduplication (subject line, date, sender)

We don't store the full content of non-receipt emails.

#Compliance

  • OAuth 2.0 authentication (we never see your password)
  • Google Cloud verified application
  • GDPR compliant data handling

#Scan settings

#Scan frequency

LUMA scans your inbox periodically for new receipts. You can trigger a manual scan:

  1. Go to Inbox → Settings
  2. Click Sync now next to Gmail

#Historical receipts

When first connected, LUMA looks back at recent emails (typically the last 30-90 days) to capture existing receipts. After that, it monitors for new emails.

#Troubleshooting

#Missing receipts

If some receipts aren't being captured:

  • Check spam/trash: We don't scan those folders
  • Unusual format: Some receipt formats aren't recognized
  • Manual forward: Forward specific receipts to your inbox email address
  • Wait for sync: New emails may take a few minutes to process

#Too many non-receipts

If non-receipt emails are appearing:

  • The AI sometimes misidentifies promotional emails as receipts
  • Delete unwanted items from your LUMA inbox
  • Add the sender to your blocklist in Inbox → Settings

#Duplicate receipts

Duplicates can occur if you:

  • Forward manually and have auto-capture on
  • Receive the same receipt to multiple email addresses

LUMA attempts to deduplicate, but delete any that slip through.

#Connection issues

If the connection stops working:

  1. Go to Inbox → Settings
  2. Click Reconnect next to Gmail
  3. Re-authorize the connection

Google may require re-authorization periodically for security.

#Disconnect Gmail

To stop automatic capture:

  1. Go to Inbox → Settings
  2. Click Disconnect next to Gmail

#Revoke from Google

You can also revoke access from your Google Account settings:

  1. Find "LUMA" in your connected apps
  2. Click Remove Access

Receipts already in your LUMA inbox remain; no new receipts will sync.

#Tips

  • Use alongside forwarding: Belt and suspenders approach for maximum capture
  • Review weekly: Check your LUMA inbox for unmatched items
  • Confirm matches: The AI learns from your confirmations
  • Use blocklist: Block senders of unwanted non-receipt emails
