Grizzly Privacy Policy

Last updated: January 13, 2026

Grizzly is a browser extension developed by Upstream Labs that helps users identify potentially deceptive or phishing websites.

Information Collection and Use

Grizzly does not collect, store, or sell personal user information.

The extension may analyze characteristics of the website currently being viewed in order to detect indicators commonly associated with phishing or deceptive behavior. This analysis is performed solely to provide warnings and improve user awareness before sensitive information is entered.

Grizzly does not collect or store:

• Personally identifiable information (such as name, email address, or account identifiers)

• Passwords, credentials, or form input contents

• Browsing history

• Financial or payment information

• Personal communications

Any data processed by the extension is used exclusively to support its single purpose of phishing detection.

Data Sharing

Grizzly does not sell, rent, or transfer user data to third parties.

Any data that may be processed as part of security analysis is used only to operate the service and only for purposes directly related to the extension’s functionality.

Data Retention

Grizzly does not retain personal user data.

Any non-sensitive, temporary data used to support functionality (such as cached analysis results or user preferences) is stored locally and may be cleared at any time.

Security

Reasonable technical and organizational measures are taken to ensure that data processed by the extension is protected and used only for its intended purpose.

Changes to This Policy

This privacy policy may be updated from time to time. Any changes will be reflected on this page with an updated revision date.
