What Sequence does

Sequence connects to your Gmail account to automatically find and organize travel receipts — flights, hotels, rides, and food delivery — into business trip summaries. It reads only emails from known travel senders. It never reads personal email, never sends email, and never modifies or deletes anything in your inbox.

What we access

We request the gmail.readonly OAuth scope, which gives read-only access to your Gmail account. We filter by sender — only emails from airlines, hotels, ride apps (Uber, Lyft), and food delivery services are fetched. All other email is ignored and never read.

What we store

We store only structured fields extracted from receipt emails:

  • Vendor name, receipt type, date, and amount
  • Travel details: origin, destination, check-in/out dates, booking reference
  • Email subject line and sender address (for deduplication)

Email body text is never stored in our database. Your Gmail credentials are never stored — only a short-lived OAuth access token used during sync.

Third-party AI processing

When structured fields cannot be extracted from an email automatically, a portion of the email subject and body (up to 6,000 characters) is sent to Anthropic's Claude API for extraction. This text is used solely to pull out receipt fields (dates, amounts, vendor names) and is not used to train Anthropic's models. See Anthropic's privacy policy for details on how they handle API data.

Data storage

Extracted receipt data is stored in a Supabase-hosted Postgres database. Each user's data is scoped to their account and is not shared with other users or third parties. Supabase is hosted on AWS infrastructure in the United States. See Supabase's privacy policy for infrastructure details.

Data deletion

You can delete all your data at any time from the dashboard settings. This permanently removes all stored receipts and sync history. You can also revoke Sequence's Gmail access at any time from your Google account permissions page.

Google API scopes

Sequence's use of Google user data is limited to what is described in this policy. We do not use Gmail data for advertising, to build user profiles, or for any purpose other than providing the receipt-organization service described above. This policy is consistent with Google's API Services User Data Policy, including the Limited Use requirements.
