Privacy Policy

At InvoiceSorter.app, your privacy is our top priority. We believe in complete transparency about how we handle your data. This policy explains exactly what we collect, what we don't, and where your data goes.

How Your Data Flows

We never store your emails. Here's exactly what happens when you use InvoiceSorter.app:

1. Gmail Read Access

We use read-only OAuth 2.0 to scan your inbox for invoice-related emails. We never modify, delete, or send emails.

2. Metadata Extraction

Our AI reads the email content in real-time and extracts only invoice metadata: vendor, amount, date, invoice number.

3. Metadata Stored

Only the extracted invoice metadata is stored in our encrypted database. No email content, no attachments, no personal messages.

4. Export to You

All exports go directly to your Google Drive, Google Sheets, QuickBooks, DATEV, or CSV download. We keep no copies.

The Bottom Line

Your Gmail emails and attachments are never stored on our servers. We only extract and store structured invoice metadata (vendor name, amount, date, invoice number, category). All file exports go directly to your own cloud storage or accounting software. You can delete all your data from our system at any time.

2. What Data We Collect

2.1 Account Information

When you sign up with Google OAuth, we receive and store:

  • Your Google account email address
  • Your display name
  • Your Google profile picture URL
  • OAuth access and refresh tokens (encrypted)

2.2 Invoice Metadata (Extracted Data)

When our AI scans your Gmail for invoices, we extract and store only the following structured metadata:

Vendor / supplier name
Invoice number
Invoice amount and currency
Invoice date and due date
Payment status
Category (auto-assigned)
Email subject line (for reference)
Gmail message ID (for deduplication)
Attachment filename (not the file itself)

2.3 Usage & Analytics Data

We collect anonymized usage metrics such as page views, feature usage frequency, and error logs to improve our service. We do not use third-party tracking or advertising cookies. We do not sell or share analytics data with any third party.

3. What We Do NOT Permanently Store

Transparency and data security are extremely important to us. We want to clearly explain how InvoiceSorter handles your data.

InvoiceSorter processes invoice emails only for the purpose of extracting invoice data and supporting your selected exports. We do not permanently store or retain your email data on our servers.

We do NOT store:

Your full Gmail email content or body text
Personal emails that are not related to invoices
Your Gmail contacts or address book
Your Gmail drafts or sent messages
Your Google Calendar or other unrelated Google services data
Your Google account password (authentication is handled via Google OAuth)
Your Google Drive files outside of invoices you choose to export
Credit card numbers (payments are handled securely by Stripe)

What we do store

We store only extracted invoice metadata (such as vendor, amount, date, and invoice number) and your account information in our encrypted database so you can use the dashboard and your chosen exports.

When you delete an invoice from the dashboard, that invoice’s metadata is permanently removed from our database.

How invoice data is handled

Invoice attachments (such as PDF invoices) may be processed temporarily to extract invoice information and complete exports. These files are not permanently stored by InvoiceSorter and are removed after processing.

If you enable Google Drive export or sync, invoices are saved directly to your own Google Drive account, where you remain the full owner and controller of your documents.

4. Gmail API & Google User Data Policy

InvoiceSorter.app's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Limited access: We only request the minimum Gmail scopes needed to read email messages for invoice extraction. We request gmail.readonly scope. For export features, we request only the minimum destination scopes required (for example, Google Drive scopes when you enable Drive export).

Limited use: We only use Gmail data to extract invoice information. We do not use it for advertising, market research, or any purpose other than providing the invoice extraction service.

Limited storage: We do not store email content. Only extracted invoice metadata is retained. OAuth tokens are encrypted at rest using AES-256 encryption.

No sharing: We do not sell, rent, lease, or transfer your Google user data to third parties for advertising, data brokering, or information reselling. We only share data with contracted subprocessors as needed to provide the service (for example, hosting, payments, and AI extraction).

5. How We Use Your Data

We use the data we collect solely for the following purposes:

  • Provide the service: Extract, categorize, and display your invoice data in your dashboard.

  • Enable exports: Send your invoice data to your chosen destination (Google Drive, Google Sheets, QuickBooks, DATEV, or CSV download) when you enable those integrations.

  • Generate analytics: Show you spending insights, trends, and reports based on your own invoice data.

  • Account management: Manage your subscription, billing, and account preferences.

  • Service improvement: Improve AI extraction accuracy and user experience using anonymized, aggregated data.

  • Communication: Send essential service notifications (e.g., billing alerts, usage limits). We do not send marketing emails without your explicit opt-in.

6. Exports & Data Destinations

When you export your invoice data, it goes directly to your chosen destination. We act as a pass-through and do not retain copies of exported data after export processing completes.

Google Drive

Files are saved directly to your own Google Drive account.

Google Sheets

Data is written directly to a spreadsheet in your Google account.

QuickBooks

Invoice data is pushed directly to your QuickBooks account via their API.

DATEV

Export files are generated in DATEV format and delivered to your system.

CSV Download

File is generated on-the-fly and downloaded directly to your device.

PDF Export

Invoices are formatted and downloaded directly to your device.

7. Security Measures

We implement industry-standard security practices to protect your data:

Encryption at rest

All stored data is encrypted using AES-256 encryption in our PostgreSQL database hosted on Neon.

Encryption in transit

All communication uses TLS 1.3 encryption. No data is ever transmitted over unencrypted connections.

OAuth 2.0 authentication

We never see or store your Google password. Authentication is handled entirely by Google's secure OAuth flow.

Token encryption

Your Gmail OAuth access and refresh tokens are encrypted at rest and only decrypted at the moment of use.

Serverless infrastructure

Our backend runs on Vercel serverless functions with no persistent servers to compromise.

Minimal data retention

We store only invoice metadata. No email content, no attachments, no unnecessary data.
