Connect your Gmail account to automatically capture receipts and invoices from your email. No manual forwarding required.
#How it works
Once connected, LUMA:
- Scans your inbox for emails that look like receipts and invoices
- Uses AI to identify transaction-related emails
- Extracts attachments and relevant data
- Sends them to your LUMA inbox for matching
The scanning happens automatically on a regular schedule.
#Connect Gmail
- Go to Inbox → Settings
- Click Connect Gmail
- Sign in to your Google account
- 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:
| Permission | What it allows | What we do |
|---|---|---|
| Read emails | View email content | Scan for receipt-like patterns |
| Read attachments | View email attachments | Extract 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:
- Go to Inbox → Settings
- 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:
- Go to Inbox → Settings
- Click Reconnect next to Gmail
- Re-authorize the connection
Google may require re-authorization periodically for security.
#Disconnect Gmail
To stop automatic capture:
- Go to Inbox → Settings
- Click Disconnect next to Gmail
#Revoke from Google
You can also revoke access from your Google Account settings:
- Find "LUMA" in your connected apps
- 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
