Terms of Service

1. Service Description

Thirty is an open-source AI-powered calendar service, developed and maintained by Thirty, that helps users organize and manage events. The source code is available under the MIT License. These Terms apply only when you use our hosted version of Thirty (e.g., https://thirtycalendar.com), not when you self-host the software.

When connected to Google Calendar, the Service only reads and imports your calendar data into Thirty for display and organization purposes. It does not create, modify, or delete events in your Google Calendar.

• Attempt unauthorized access to any systems, networks, or user accounts.
• Use the Service to transmit unlawful, abusive, or harmful content.
• Collect or harvest user data without consent.
• Violate the intellectual property or privacy rights of others.

4. Accounts

You may need to create an account to access certain hosted features. You are responsible for maintaining the confidentiality of your credentials and all activity under your account. Notify us immediately if you suspect unauthorized access.

5. Subscriptions and Payments
