Privacy Policy

Effective as of July 29, 2025

This Privacy Policy explains how Sundial Scheduling, LLC (“Sundial”, “we”, “us”) collects, uses, and protects your data when you use the Sundial Chrome extension. It outlines our minimal data collection practices, calendar and email access limitations, data retention, and your rights.

Account Data and Usage Tracking

We collect your email address during authentication and track basic feature usage metrics (e.g. which features are used and how often). This information is used solely to improve your experience and the performance of the Sundial extension.

We do not store any calendar or email content. We store your email address and feature usage metadata only. This data is never sold and is not shared with third parties except where required to provide our Services (e.g., hosting, processing).

Aggregated Usage

We may use anonymized, aggregated usage data across our user base to improve features and design.

Data Deletion

If your account or your organization terminates your subscription, you may delete your user or team data in your dashboard here or request deletion of associated by contacting us at support@trysundial.ai. We will honor deletion requests within 30 days and confirm completion upon request, unless required to retain data by law or for legitimate business purposes (e.g., fraud prevention).

Google Calendar Access

Sundial requests two types of access to your Google Calendar data:

API Access

Sundial requests permission to access your Google Calendar data using the scope https://www.googleapis.com/auth/calendar.events. This scope is used solely to allow our extension to delete multiple calendar events at once and only upon your explicit command.

Host Permissions

We have host permissions to interact with content on https://calendar.google.com/*.

How We Use This Access

Always User-Initiated

Whether through API access or direct interaction via host permissions, we only access your calendar to perform the features you request. All actions are performed based only on your explicit commands.

No Storage

We do not store any calendar event details (e.g., titles, attendees, etc). Any calendar event data accessed through API calls or host permissions is processed locally within your browser and only for the duration necessary to perform the requested action.

Gmail Access

Sundial also requests host permissions to access content on https://mail.google.com/*.

How We Use This Access

Always User-Initiated

We only access your Gmail to perform the features you request (e.g. overlaying meeting times atop your calendar that are found in an email). All actions are performed based only on your explicit commands.

No Storage

We do not store any email details we process (e.g., user selected email body content and its sent datetime).

Processing

The only email data accessed are user-selected email body content and its sent datetime. This information is processed by a fine-tuned LLM (OpenAI’s GPT-4.1 Mini 2025-04-14) only for the duration necessary to perform the requested action. The LLM is called via an API endpoint on Render.com.

Data Protection and Sharing

All infrastructure used to process your data is U.S.-based. We do not sell, rent, or otherwise share your personal information with third parties. Your data is kept strictly confidential, and we only use it for the purposes outlined in this privacy policy.

In the event of a data breach affecting your personal information, we will notify affected users as required by law and within 72 hours where applicable.

User Rights

You have the right to access and delete your data. If you wish to do so, please contact us at support@trysundial.ai.

Changes to Our Privacy Policy

We may update this privacy policy from time to time to reflect changes in our practices or to comply with new legal requirements. We will notify you of any changes to our privacy policy by posting the new policy on our website.
