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.
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).
We may use anonymized, aggregated usage data across our user base to improve features and design.
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).
Sundial requests two types of access to your Google Calendar data:
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.
We have host permissions to interact with content on https://calendar.google.com/*.
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.
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.
Sundial also requests host permissions to access content on https://mail.google.com/*.
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.
We do not store any email details we process (e.g., user selected email body content and its sent datetime).
The only email data accessed are user‑selected email body content and its sent datetime. This data is sent to OpenAI’s GPT‑4 Turbo model via an API endpoint hosted on Render.com. Sundial and Render do not store this data. OpenAI may temporarily store and log the data for up to 30 days for operational monitoring and abuse‑prevention purposes, after which it is deleted. OpenAI does not share or use this data for model training. These providers serve as subprocessors solely for the purpose of fulfilling your requested feature.
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.
You have the right to access and delete your data. If you wish to do so, please contact us at support@trysundial.ai.
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.
If you have any questions or concerns about our privacy policy or the data we collect, please contact us at support@trysundial.ai. We are happy to address any concerns you may have.
