Privacy Policy

Last updated: May 2026

1. Information We Collect from Account Holders

When you sign up for and use Kesper, we may collect the following information about you (the merchant or operator):

  • Account information: Name, email address, and business details provided during registration.
  • Business data: POS and marketplace data including transactions, inventory levels, orders, and product listings.
  • Marketing data: Campaign performance, ad spend, and engagement metrics from connected platforms.
  • Usage data: How you interact with the Kesper dashboard and agents, including page views and feature usage.

2. Customer Data We Process on Behalf of Shopify Merchants

When a Shopify merchant installs Kesper, we process a limited set of their customers' personal data on their behalf, as a data processor. The merchant remains the data controller; Kesper processes this data solely to provide the contracted Service.

Fields processed:

  • Name — used to dedupe customers across orders for variant-level margin attribution.
  • Email — primary dedup key across POS-imported and Shopify-native orders.
  • Phone — fallback dedup identifier when email is missing on a record.
  • Address — aggregated to the first three digits of the ZIP/postal code (ZIP-3) for region-grouping orders to the correct store P&L. Full addresses are never displayed in the merchant-facing brief.
  • Order data — used for daily POS-vs-Shopify reconciliation, margin analysis (SCROOGE agent), and ghost-stock detection (SHERLOCK agent).

What we do not do: We do not sell, rent, or license this customer data. We do not use it for advertising, marketing to end customers, or personalization outside the merchant's operational brief. End-customer PII is never displayed to district managers or other merchant staff — only aggregate signals derived from it.

Retention: Customer data tied to a merchant is retained for the duration of their active subscription and purged within 30 days of uninstall, triggered by Shopify's shop/redact webhook. Individual customer deletion requests via customers/redact are honored immediately.

3. How We Use Your Information

We use the information we collect to:

  • Power AI agents that analyze your business operations.
  • Generate reports, alerts, and actionable business intelligence.
  • Provide inventory management, margin analysis, and marketing recommendations.
  • Improve and maintain the Service.
  • Communicate with you about your account, updates, and support requests.

4. Third-Party Services (Sub-Processors)

Kesper relies on the following sub-processors to operate the Service:

  • Hosting & database: Railway hosts the Kesper API and managed PostgreSQL database in US regions.
  • Billing: Stripe processes payments for merchants who sign up directly at kesper.io. Merchants installing from the Shopify App Store are billed through Shopify's subscription billing API instead.
  • Notifications: Slack delivers alerts and daily briefs to your workspace.
  • Marketplace APIs: Shopify, eBay, Amazon, and other platforms provide product and sales data when you connect your accounts.
  • AI providers: Anthropic, OpenAI, and NVIDIA (Kimi K2.5) process prompts to power agent analysis and recommendations. We do not send raw end-customer PII to AI providers — only aggregate signals.
  • Transactional email: Resend delivers account and operational emails on our behalf.

5. Data Storage & Security

Your data is stored on Railway infrastructure located in the United States. The managed PostgreSQL database encrypts data and backups at rest using AES-256. Marketplace credentials and API keys receive an additional layer of app-level field encryption (AES-256-GCM). All data in transit is protected with HTTPS/TLS 1.2+. Passwords are hashed using scrypt with a 16-byte random salt. Sessions use server-revocable Bearer tokens. Access to merchant data within Kesper is restricted by role, with data-touching mutations recorded to an immutable audit log.

6. Data Sharing

We do not sell your personal or business data, and we do not sell the personal data of your end customers. Data is shared only with the sub-processors listed above, and only to the extent necessary to operate the Service:

  • AI providers receive prompt data to generate analysis and recommendations. End-customer PII is not included in these prompts.
  • Billing providers (Stripe or Shopify) process payment information to manage your subscription.
  • We may disclose data if required by law, subpoena, or legal process.

7. Cookies & Analytics

Kesper uses minimal tracking. We store a session token in your browser's localStorage to keep you signed in. We do not use third-party tracking cookies. We use Plausible Analytics, a privacy-friendly analytics tool that does not use cookies and does not collect personal data. Plausible is fully compliant with GDPR, CCPA, and PECR.

8. Your Rights

You have the right to access, export, and delete your data at any time. To exercise these rights, contact us at support@kesper.io. We will respond to your request within 30 days. End customers of Shopify merchants should direct requests to the merchant; we will process verified deletion requests forwarded by the merchant or received through Shopify's customers/redact webhook.

9. CCPA Compliance

If you are a California resident, you have the right to request deletion of your personal information, know what personal information is being collected, and opt out of the sale of your personal information. As stated above, we do not sell personal data. To submit a CCPA request, email support@kesper.io.

10. GDPR Compliance

If you are located in the European Union, you have the right to access, rectify, erase, and restrict the processing of your personal data. You also have the right to data portability and the right to object to processing. To exercise any of these rights, contact support@kesper.io.

11. Data Retention

We retain your account data for as long as your account is active. If you cancel your account, your data will be available for export for 30 days. After that period, all account data is permanently deleted from our systems. Customer data processed on behalf of Shopify merchants follows the retention rules described in Section 2.

12. Children

Kesper is not intended for use by anyone under the age of 18. We do not knowingly collect personal information from children. If we become aware that we have collected data from a minor, we will delete it promptly.

13. Changes to This Policy

We may update this Privacy Policy from time to time. Updated versions will be posted on this page with a revised effective date. We encourage you to review this page periodically.
