6. Shopify Data Handling

SegmentFlow integrates with Shopify to access your store data. This section explains how we handle this integration:

What We Access

Through Shopify's OAuth authorization, we access customer profiles, order history, product catalog, and store branding. We only request permissions necessary to provide our service.

How We Use Shopify Data

  • Customer data is used to build segments based on your criteria (e.g., "customers who bought twice")
  • Order data enables revenue attribution and purchase-based segmentation
  • Product data allows us to include relevant products in your campaigns
  • Branding assets (logos, colors) are used to generate on-brand email templates

Data Isolation

Your Shopify data is isolated to your account. We do not share, combine, or cross-reference data between different SegmentFlow users. Each merchant's data remains completely separate.

Shopify's Role

Shopify maintains control over the data in your Shopify store. When you disconnect SegmentFlow from Shopify or revoke access, we lose the ability to access new data from your store.

7. AI/ML Data Processing

SegmentFlow uses artificial intelligence and machine learning to power its core features. Here's how we handle AI processing:

How AI Processes Your Data

  • Segment Creation: AI interprets your natural language descriptions and queries your customer data to build matching segments
  • Content Generation: AI generates email copy and designs based on your brand assets, products, and campaign goals
  • Analytics: AI helps analyze campaign performance and provide insights

Your Data and AI Training

We do not use your customer data or campaign content to train general-purpose AI models that would be used for other customers. Your data is processed only to provide services to you.

Automated Decision-Making

Our AI makes automated suggestions for segments and content, but you retain full control. All segments and campaigns require your review and approval before any emails are sent. We do not make fully automated decisions that significantly affect your customers without your explicit action.

Third-Party AI Services

We may use third-party AI services (such as language models) to power certain features. When we do, we ensure these providers maintain appropriate data protection standards and do not retain your data for their own purposes.

8. Email Campaign Data

When you send email campaigns through SegmentFlow, we collect and process the following data:

Tracking Data

  • Opens: When and whether recipients open your emails
  • Clicks: Which links recipients click within your emails
  • Bounces: Emails that could not be delivered
  • Unsubscribes: Recipients who opt out of future emails

Revenue Attribution

We connect email engagement data with Shopify order data to show you which campaigns generate revenue. This helps you understand the direct business impact of your marketing efforts.

Compliance Features

SegmentFlow automatically includes unsubscribe links in all marketing emails and processes unsubscribe requests to help you comply with CAN-SPAM, GDPR, and other email marketing regulations.

9. Data Sharing

We may share your information with:

Service Providers

We work with trusted third-party providers who help us operate our service, including:

  • Cloud hosting and infrastructure providers
  • Email delivery services
  • Analytics services
  • AI/ML service providers

These providers are contractually bound to protect your data and may only use it to provide services to us.

Legal Requirements

We may disclose your information if required by law, legal process, or government request, or to protect the rights, property, or safety of SegmentFlow, our users, or the public.

Business Transfers

If SegmentFlow is involved in a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction. We will notify you of any such change.

No Selling of Data

We do not sell your personal data or your customers' data to third parties.

10. International Data Transfers

When we transfer data outside the EU/EEA, we ensure appropriate safeguards are in place, including:

  • EU Standard Contractual Clauses

  • Usage logs: Typically retained for 12 months for security and debugging purposes

Upon account termination, we delete your data within 30 days, unless we are legally required to retain it longer. You may request data export before closing your account.

12. Data Security

We implement appropriate technical and organizational measures to protect your data, including:

  • Encryption of data in transit (TLS/SSL) and at rest
  • Secure authentication and access controls
  • Regular security assessments and updates
  • Employee training on data protection
  • Incident response procedures

While we strive to protect your data, no method of transmission or storage is 100% secure. We cannot guarantee absolute security.
