Introduction

CalendarBG ("Backgrounds for Google Calendar") is a Chrome extension that allows users to customize their Google Calendar with background images. This privacy policy explains how we collect, use, and protect your data.

Data We Collect

When you sign in with Google, we receive your name, email address, and profile photo via Google OAuth. This is used to identify your account and manage your subscription.

Usage Data

We collect anonymous usage analytics (e.g., which features are used, search queries) to improve the extension. This data is not linked to your personal identity.

Google Drive Access

If you choose to use Google Drive photos as backgrounds, we request read-only access to your Drive files. We only access image files and never modify or delete any files. This access is used solely to display your photos as calendar background options.
