1. Acceptance of Terms

By downloading, installing, or using Cosmos Chat ("the App"), you agree to be bound by these Terms and Conditions ("Terms"). If you do not agree to these Terms, do not use the App.

These Terms constitute a legal agreement between you and Cosmos One ("we", "us", or "our"). We reserve the right to modify these Terms at any time. Continued use of the App after changes constitutes acceptance of the modified Terms.

You must be at least 13 years of age to use Cosmos Chat.

2. Description of Service

Cosmos Chat is an AI-powered chat application that runs entirely on your device. The App provides:

  • On-device AI chat using locally downloaded language models

  • Semantic search across conversations using on-device embeddings
  • Optional Hugging Face authentication for accessing gated AI models

The App requires a one-time internet connection to download AI models. After models are downloaded, core AI functionality works entirely offline.

The App displays banner ads via Google AdMob (with your consent). You may purchase "Remove Ads" to permanently disable all advertising.

4. Licence Grant

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable licence to download, install, and use the App for personal, non-commercial purposes.

Llama 3.2 3B Meta Llama 3.2 Community Licence Acceptable use policy applies; "Built with Llama" attribution
Nomic Embed v1.5 Nomic AI Apache 2.0 Open source
Whisper Tiny OpenAI MIT Open source

By using the App, you agree to comply with all applicable AI model licence terms:

Prohibited uses include but are not limited to:

  • Generating content that violates laws or regulations
  • Generating content that promotes violence or harm
  • Generating deceptive or fraudulent content
  • Generating content that infringes on intellectual property rights
  • Using models for surveillance or tracking individuals

6. User Content

"User Content" includes any text, prompts, or other content you input into the App.

You retain full ownership of your User Content.

You represent that your User Content does not:

  • Violate any applicable laws or regulations
  • Infringe on third-party intellectual property rights
  • Contain malicious code or harmful content
  • Violate any AI model usage policies

Your User Content is stored locally on your device and is NOT transmitted to us or any third party. The only network activity involving your content occurs during optional Hugging Face OAuth authentication, which transmits only authentication data — never your conversations.

We do not claim any ownership or licence over your User Content. We have no ability to access, read, or process your conversations.

Content never leaves your device unless you explicitly export it via the Android share sheet (e.g., sharing diagnostic logs).

The App offers optional integration with Hugging Face for accessing gated AI models (such as Google Gemma).

If you choose to sign in with Hugging Face:

  • Authentication tokens are stored securely on your device using AES-256-GCM encryption
  • We only use authentication to download gated models on your behalf
  • We request the scopes openid, profile, and read-repos
  • We do NOT access your Hugging Face repositories, datasets, or other account data

You may revoke Hugging Face access at any time by signing out within the app or visiting https://huggingface.co/settings/connected-applications.
