GlassTab — Privacy Policy

Last updated: March 27, 2026

Overview

GlassTab ("the Extension") is a Chrome browser extension that replaces your new tab page with a customizable dashboard. This Privacy Policy describes how the Extension accesses, uses, stores, shares, and protects user data, including data obtained through Google APIs.

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

1. Data Accessed

GlassTab accesses the following types of data:

Google User Data

If the user chooses to connect their Google account, GlassTab requests read-only access to Google Calendar data using the calendar.readonly scope. Specifically, the Extension accesses:

No other Google user data is accessed. GlassTab does not access Gmail, Google Drive, Google Contacts, or any other Google services.

Non-Google Data

User Preferences (Local Only)

2. Data Usage

GlassTab uses the data it accesses solely to provide the Extension's core functionality:

GlassTab does not use any data for advertising, analytics, profiling, market research, or any purpose unrelated to providing the Extension's features.

GlassTab does not use Google user data to train artificial intelligence or machine learning models.

3. Data Sharing

GlassTab does not share, sell, rent, or transfer any user data — including Google user data — to any third parties. This includes:

The only network requests made by the Extension are:

These requests are made directly from the user's browser. No intermediary servers are involved.

4. Data Storage & Protection

All user data is stored locally on the user's device using Chrome's built-in storage APIs (chrome.storage.local and localStorage). No data is stored on external servers or in cloud databases.

Google Calendar Data

Calendar event data is held only in the browser's working memory (RAM) during the active browser session. It is re-fetched from Google's API each time the user opens a new tab. Calendar data is not written to persistent storage, cached to disk, or stored beyond the current session.

OAuth Tokens

For non-Chrome browsers (Edge, Brave, etc.) that use the web-based OAuth flow, the access token is stored in localStorage with an expiration timestamp. The token is automatically cleared when it expires (approximately 1 hour). Users can revoke access at any time by clicking "Disconnect" in the Extension's settings, which also deletes the stored token and revokes it with Google.

Security Measures

5. Data Retention & Deletion

Retention

Deletion

Users can delete their data at any time through the following methods:

Since no data is stored on external servers, there is no server-side data to request deletion of.

Google API Services Limited Use Disclosure

GlassTab's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Cookies & Tracking

GlassTab does not use cookies, analytics, tracking pixels, or any form of user tracking or monitoring.

Children's Privacy

The Extension is not directed at children under the age of 13 and does not knowingly collect data from children.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated revision date. Continued use of the Extension after changes constitutes acceptance of the updated policy.
