Privacy Policy

Last updated: March 11, 2026

Introduction

This Privacy Policy explains how kyrusin ("we," "us," or "our") collects, uses, and protects information when you use our Chrome extensions and related services. We are committed to protecting your privacy and handling your data with transparency.

Information We Collect

Information you provide

When you sign in through Google OAuth, we receive basic profile information from your Google account, which may include:

• Your name and email address
• Your Google profile picture
• A unique Google account identifier

Information collected automatically

Our extensions may collect limited data necessary for functionality, such as:

• Extension usage and interaction data
• Browser type and version
• Error logs and crash reports

Google OAuth & API Scopes

Our extensions use Google OAuth 2.0 to authenticate your identity. We only request the minimum scopes necessary for the extension to function. We do not request access to your data beyond what is explicitly described in the permission prompts shown during sign-in.

Our use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

How We Use Your Information

We use the information we collect to:

• Provide, maintain, and improve the extension's functionality
• Authenticate your identity and manage your session
• Communicate with you about updates or changes to the extension
• Diagnose technical issues and improve performance

Data Storage & Security

We store data locally in your browser using Chrome's storage APIs where possible. Any data transmitted to external servers is encrypted in transit using HTTPS. We implement reasonable security measures to protect your information from unauthorized access, alteration, or destruction.

Data Sharing

We do not sell, trade, or rent your personal information to third parties. We may share information only in the following circumstances:

• With your explicit consent
• To comply with legal obligations or enforceable governmental requests
• To protect our rights, privacy, safety, or property

Data Retention

We retain your data only for as long as necessary to provide the extension's services. You may delete your data at any time by uninstalling the extension, which removes all locally stored data. If you wish to request deletion of any server-side data, please contact us.

Third-Party Services

Our extensions may interact with third-party services (such as Google APIs). These services have their own privacy policies, and we encourage you to review them:

• Google Privacy Policy
• Google Chrome Privacy Notice

Your Rights

Depending on your jurisdiction, you may have the right to:

• Access, correct, or delete your personal data
• Withdraw consent for data processing
• Request a copy of your data in a portable format
• Object to or restrict certain processing activities

Children's Privacy

Our extensions are not directed at children under the age of 13. We do not knowingly collect personal information from children. If we become aware that we have collected data from a child under 13, we will take steps to delete that information promptly.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes by updating the "Last updated" date at the top of this page. Continued use of our extensions after changes constitutes acceptance of the updated policy.
