Terms of Service
This is a draft. It may change after legal review before launch.
Last updated: November 9, 2026
At a glance
- The app is free.
- Characters talk through the AI you connect. AI costs come out of your own plan with that company.
- Connecting a ChatGPT or Claude subscription may not be a route those companies officially offer. If that worries you, connect with an API key instead.
- Your chats and memories stay on your computer.
1. About these Terms
These Terms of Service ("Terms") set out the conditions for using the Mongi app and website (the "Service") provided by [Operator name] ("we," "us" or "our").
2. The Service
- The app shows a character on your computer screen and lets that character talk with you through an AI service you connect.
- You can download the app for free from our website.
- When a new version is available, the app may download and install it on its own.
3. AI connections and costs
- Characters talk using an AI service you connect yourself: a ChatGPT subscription, a Claude subscription, or an OpenAI or Anthropic API key.
- The cost of using AI is governed by your own plan or agreement with that company. We do not collect AI costs from you or pay them on your behalf.
- Answers generated by AI may be inaccurate. Please don't rely on what a character says when making important decisions.
4. Connecting a ChatGPT or Claude subscription
- The app offers a way to talk with characters using a ChatGPT or Claude subscription you already have. This connection may not be a method officially provided or approved by OpenAI or Anthropic.
- Depending on each company's policies, the connection may stop working without notice, your subscription usage may be restricted, or action may be taken against your account.
- Whether to use a subscription connection is your choice. We are not responsible for any account or usage restrictions that result from using a subscription connection.
- Your sign-in details and tokens are stored only on your computer and are never sent to our servers. Chat requests go directly from your computer to the company concerned.
- If you'd rather avoid this risk, you can connect with an OpenAI or Anthropic API key instead.
5. Rights to characters
All rights to the artwork, writing and settings of the characters that come with the app belong to us or to the artist who created them. You may use them for personal purposes within the app, but you may not extract, distribute or sell them separately.
6. Your data
Your chat history, memories and settings are stored on your computer and are never sent to our servers. See our Privacy Policy for details.
7. What you may not do
- Copy, modify or distribute the app or its characters without permission.
- Interfere with the operation of the Service.
8. Limitation of liability
- We are not responsible for interruptions, changes, errors or charges of the AI services you connect.
- If you suffer harm because of our intentional misconduct or gross negligence, we will be liable as required by applicable law.
9. Changes to these Terms
When we change these Terms, we will post a notice on our website at least 7 days before the change takes effect. For changes that are unfavorable to you, we will give at least 30 days' notice.
