Terms of Service — Cosmos Calendar

Last Updated: 24 March 2026

1. Acceptance of Terms

By downloading, installing, accessing, or using Cosmos Calendar ("the App"), you agree to be bound by these Terms of Service ("Terms"). These Terms constitute a legal agreement between you ("you", "your") and Cosmos One ("we", "us", "our").

If you do not agree to these Terms, you must stop using the App and uninstall it from your device.

2. Description of Service

Cosmos Calendar is an Android mobile application that combines AI-powered conversational assistance with Google Calendar integration. The App is powered by Cosmos Services, a cloud-based API platform operated by Cosmos One that provides AI chat services, authentication, subscription management, and usage tracking.

The App allows users to:

  • Conduct text-based conversations with an AI assistant
  • Extract and create calendar events from natural language conversations
  • Browse, edit, and delete existing Google Calendar events
  • Search across calendar events
  • Set event reminders
  • Manage subscriptions and monitor usage quotas
  • Export personal data and manage account settings

Google Calendar data is accessed directly between the App and Google's servers on your device. Calendar data does not transit through Cosmos Services servers.

3. Important Disclaimers

3.1 AI Output Limitations

Cosmos Calendar uses artificial intelligence models to generate responses and extract calendar information from conversations. AI-generated output may be inaccurate, incomplete, outdated, or inappropriate. You must:

  • Review all AI-generated content before relying on it
  • Verify any calendar events created from AI suggestions before confirming them
  • Not treat AI responses as professional, medical, legal, or financial advice

We make no guarantees regarding the accuracy, reliability, or suitability of AI-generated output for any particular purpose.

3.2 Service Availability

The App depends on external services (Google APIs, Cosmos Services, AI providers) that may experience downtime, rate limiting, or changes. We do not guarantee uninterrupted availability.

3.3 Regulatory/Compliance Note

Cosmos Calendar has not been independently audited or certified under any regulatory framework. You are solely responsible for determining whether the App is suitable for your obligations or requirements.

4. Licence Grant

We grant you a limited, non-exclusive, non-transferable, revocable licence to install and use the App on a compatible Android device that you own or control, for your personal, non-commercial use, subject to these Terms.

6. User Accounts and Authentication

6.1 Google Sign-In

Cosmos Calendar requires a Google account for authentication. By signing in, you authorise the App to access your basic profile information (name, email, profile picture) and, when you connect your calendar, your Google Calendar data as described in our Privacy Policy.

The App requests the following Google permissions:

  • openid, email, profile — for authentication and account creation

  • Notifying us promptly of any unauthorised access or use of your account
  • Ensuring your device's operating system and security features are kept up to date

Authentication tokens are stored on your device using AES-256 encrypted storage backed by the Android Keystore. If your device is compromised, your tokens may be at risk. We recommend enabling device-level security (PIN, biometrics, or password).
