Privacy Policy

Overview

WarehouseWatcher is a price-tracking tool that monitors publicly available gold bar prices at major retailers and alerts you when premiums drop near the spot price. We are committed to keeping your data minimal and private.

Data We Collect

• Anonymous identifier — We use Supabase Anonymous Authentication to create a session. No email, password, name, or personal information is required or collected.
• Push notification token — If you enable push notifications, your device's Firebase Cloud Messaging (FCM) token is stored so we can deliver price alerts. This token is a random device identifier and cannot be used to identify you personally.
• User preferences — Your alert threshold setting (e.g., premium percentage) is stored to customize notifications.

Data We Do NOT Collect

• No name, email address, or contact information
• No location data
• No browsing or usage analytics
• No financial or payment information
• No advertising identifiers

How We Use Your Data

The anonymous identifier and FCM token are used solely to deliver push notifications about price changes. User preferences are used to determine when to trigger alerts. We do not use your data for any other purpose.

Third-Party Services

• Supabase — Database and anonymous authentication (Supabase Privacy Policy)
• Firebase Cloud Messaging — Push notification delivery (Firebase Privacy Policy)

We do not share, sell, or transfer your data to any other third parties.

Data Retention

FCM tokens are automatically removed when push delivery fails (e.g., app uninstalled). Anonymous session data and preferences are retained as long as the session is active. There is no account to delete — simply uninstalling the app removes your device token and ends your session.

Children's Privacy

This app is not directed at children under 18. We do not knowingly collect data from children.

Changes to This Policy

We may update this policy from time to time. Changes will be reflected on this page with an updated effective date.
