Privacy Policy

Last updated: April 23, 2026

1. Introduction

Stocklet ("we," "our," or "us") provides a Shopify application that captures customer email addresses on sold-out product variants and sends transactional back-in-stock notifications when inventory returns. This Privacy Policy describes what information we collect, how we use it, and how we protect it.

By installing or using Stocklet, you agree to the practices described in this policy.

2. Information We Collect

2.1 Store Information

When you install Stocklet, we receive and store basic information about your Shopify store, including:

  • Your Shopify store domain
  • Store name and contact information
  • Shopify access tokens required for API communication

2.2 Subscriber Information

When a customer signs up on a sold-out variant in your store, we store:

  • The customer's email address
  • The Shopify variant ID they signed up for
  • The timestamp of the subscription
  • Notification status (pending, notified, and when they were emailed)

We do not collect names, IP addresses for marketing, behavioral tracking pixels, or any other customer PII beyond what is voluntarily entered into the back-in-stock form.

2.3 Inventory and Product Data

We receive inventory level events from Shopify webhooks to determine when to send notifications. We store minimal product and variant metadata (titles, variant IDs, inventory quantities) necessary to match subscribers to the correct restock events.

2.4 Activity Logs

We maintain operational logs of webhook deliveries, notification sends, and admin actions with timestamps for troubleshooting and support.

2.5 Billing Information

Subscription and billing are managed entirely through Shopify. We store your plan name and billing cycle dates but do not process or store payment card information.

3. How We Use Your Information

We use the collected information to:

  • Deliver back-in-stock notifications to customers who signed up on sold-out variants
  • Detect inventory changes and match restocks to the correct pending subscribers
  • Display pending and notified subscribers in your Shopify admin dashboard
  • Manage your subscription and plan allocation
  • Troubleshoot issues and provide customer support

4. Data Sharing

We do not sell, rent, or share your personal information with third parties for marketing purposes. Your data is only shared with:

  • Shopify — through their Admin API and webhooks to read inventory, verify storefront requests, and display admin dashboards
  • Resend — our transactional email provider, which delivers restock notifications on our behalf and handles bounces and delivery tracking

These integrations are essential to the core functionality of Stocklet and only transmit data necessary for sending notifications.

5. Data Security

We take the security of your data seriously:

  • All storefront form submissions are HMAC-verified through Shopify's App Proxy before any data is written
  • All data is transmitted over HTTPS encrypted connections
  • Database access is restricted and secured
  • We follow security best practices for application development and deployment

6. Data Retention and Deletion

We retain your data only as long as Stocklet is installed on your Shopify store. When you uninstall Stocklet:

  • All your data — including your store information, subscribers, and activity logs — is permanently deleted within 48 hours
  • We listen for Shopify's app/uninstalled webhook and begin automated deletion immediately

7. Your Rights

You have the right to:

  • Access the data we hold about your store and subscribers
  • Delete individual subscribers from the admin dashboard
  • Delete all your data by uninstalling Stocklet from your Shopify store
  • Request a copy of your stored data by contacting us

8. Cookies and Tracking

Stocklet does not use cookies for tracking or advertising. Session cookies required by Shopify for authentication are managed by the Shopify platform. We do not use any third-party analytics or tracking tools within the app.

9. Children's Privacy

Stocklet is a business tool intended for use by Shopify store owners. We do not knowingly collect information from children under the age of 13.

10. Changes to This Policy

We may update this Privacy Policy from time to time. If we make significant changes, we will notify you through the app or by other appropriate means. Your continued use of Stocklet after any changes indicates your acceptance of the updated policy.
