Zuuby – Privacy Policy

1 Who We Are

Zuuby is a Chrome browser extension that provides a floating AI assistant on any webpage. It is developed and maintained by an independent developer. By installing and using Zuuby, you agree to this Privacy Policy.

This extension is not affiliated with Google, OpenAI, Groq, Mistral AI, Cohere, or any AI provider it connects to.

2 What Data We Collect

We collect the minimum amount of data necessary for the extension to function. Here is a complete breakdown:

3 How We Use Your Data

Your data is used exclusively for the following purposes:

• To authenticate you via Google Sign-In when you open the extension
• To display your name and profile photo inside the extension popup
• To sync your API keys across your devices (if you choose to sign in)
• To maintain your session so you do not need to sign in repeatedly

We do not use your data for advertising, analytics profiling, or any commercial purpose beyond operating the extension.

4 AI Queries and Web Page Content

When you ask Zuuby a question, your query is sent directly from your browser to the AI provider you have selected (e.g., Google Gemini, Groq, OpenAI). These requests go directly to the provider's API using your own API key.

When you use the right-click context menu to summarise or explain selected text, only the text you explicitly selected is sent to the AI. Full page content is never captured or sent.

5 Third-Party Services

Zuuby integrates with the following third-party services. Their own privacy policies govern how they handle your data:

• Google Firebase Authentication — manages your sign-in session. Firebase Privacy Policy
• Google Firestore — stores your user profile data. Firebase Privacy Policy
• Google Gemini API — processes AI queries if you use a Gemini key. Google AI Terms
• OpenAI API — processes AI queries if you use an OpenAI key. OpenAI Privacy Policy
• Groq API — processes AI queries if you use a Groq key.
• Mistral AI API — processes AI queries if you use a Mistral key.
• Cohere API — processes AI queries if you use a Cohere key.

We recommend reviewing the privacy policies of any AI provider whose API key you choose to use.

6 Data Storage and Security

Your user profile (name, email, photo) is stored in Google Firebase Firestore, which is secured by Firebase Authentication. Only you — identified by your unique Google UID — can read or write your own data.

Your API keys are stored in Chrome's built-in chrome.storage.local, which is encrypted by Chrome and accessible only to the Zuuby extension on your device.

We do not operate our own servers. All data storage is handled through Google infrastructure.

7 Data Sharing

We may disclose data only if required by law (e.g., a valid court order), and only to the minimum extent required by that legal obligation.

8 Your Rights and Choices

You have full control over your data:

• Sign out — clicking Sign Out in the extension clears your local session and Google OAuth token
• Delete your data — email us (see contact below) and we will permanently delete your Firestore document within 7 days
• Uninstall — removing the extension from Chrome deletes all locally stored data immediately
• Revoke Google access — visit myaccount.google.com/permissions and revoke Zuuby's access at any time

9 Children's Privacy

Zuuby is not intended for use by children under the age of 13. We do not knowingly collect personal data from children. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.

10 Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. Continued use of the extension after changes are posted constitutes acceptance of the updated policy.

For significant changes, we will update the extension's description in the Chrome Web Store to notify users.
