Privacy Policy

Cartology ("we", "us", "our") values your privacy. This Privacy Policy explains how our Chrome extension collects, uses, and protects your information.

1. Data Collection and Usage

We do not collect, transmit, or store any of your personal data on our servers. The Cartology extension operates entirely locally within your browser.

• Local Processing: All analysis of your shopping history occurs directly on your device.
• No External Transmission: Your receipt data, login credentials, and personal information are never sent to us or any third parties.
• Authentication: We do not see or store your passwords. The extension relies on your existing active session with the retailer's website.

2. Data Storage

Any data generated by the extension (such as cached receipt data or analysis metrics) is stored locally in your browser's storage (IndexedDB or LocalStorage). You have full control over this data and can clear it at any time by clearing your browser's cache or uninstalling the extension.

3. Third-Party Services

Our extension functions by interacting with the official Costco website to retrieve your purchase history. We are not affiliated with, endorsed by, or connected to Costco Wholesale Corporation. Please refer to their separate privacy policy regarding your interactions with their website.

4. Changes to This Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
