Privacy Policy

Last updated: April 3, 2026

Overview

Calendar View Switcher is a browser extension that automatically toggles the visibility of Google Calendar calendars based on the current view (day, week, or month). This policy explains how the extension handles your data.

Data Collection

This extension does not collect, transmit, or share any personal data. All data stays on your device.

Data Stored Locally

The extension stores the following data in your browser's local storage (chrome.storage.local):

• Calendar names — The display names of your Google Calendar calendars, used to identify which calendars to show or hide per view.
• View profiles — Your preferences for which calendars should be visible in each view (day, week, month).

This data is never sent to any server or third party.

How the Extension Works

This extension injects a content script into the Google Calendar web page (https://calendar.google.com). The script reads the calendar sidebar's DOM to detect calendar names and their visibility states, and programmatically clicks the sidebar checkboxes to toggle calendar visibility. No page content is extracted, recorded, or transmitted.

Permissions

• storage — Used to save your calendar visibility preferences locally.
• activeTab — Used to communicate with the Google Calendar tab when you open the extension popup.
• Content script on calendar.google.com — Used to detect the current view and toggle calendar visibility in the sidebar.

Third-Party Services

This extension does not use any third-party services, analytics, or tracking.

Changes to This Policy

If this policy is updated, the changes will be reflected on this page with an updated date.
