Terms of Service

Purpose

These terms set out the conditions and procedures for using the application Charlo (the "App") provided by toya (the "Operator"), and the rights, obligations, and responsibilities of the Operator and users.

Definitions

• App · An offline character chat application that runs a language model on your device so you can talk with characters.
• User · A person who agrees to these terms and installs and uses the App.
• Character card · A file or record containing a character's name, description, first message, lorebook, and similar data, including cards bundled with the App and cards you import or create.
• Model · A Google Gemma language model file used to generate replies, which the App downloads from an external repository.
• Generated content · Replies, summaries, and other text produced by the model during a chat.

Effect and Changes

These terms take effect when you install and use the App and apply together with Apple's standard Licensed Application End User License Agreement for apps obtained from the App Store. The Operator may change these terms within the limits of applicable law and will post any changes on this page with their effective date.

Changes unfavorable to users will be announced at least 7 days before they take effect. If you do not agree to a change, you may stop using and delete the App.

The Service

The App lets you import or create character cards and chat with those characters. It supports Character Card V2 and V3 cards in .charx, .png, and .json files. When a chat grows long, the App summarizes earlier parts, and you can add or remove memories for each chat yourself.

Because replies are generated on your device, the App offers no server, accounts, or sync. To chat, you first download a model from the App's model screen. After that, the App works without an internet connection.

Language models use a lot of memory and computing power, so reply speed, heat, and battery use vary greatly by device. Each model has a recommended amount of memory (RAM), and on devices below it the model may fail to run or the App may close. You are responsible for providing a suitable device, storage space, and operating system version.

Purchase and Payment

The App is a paid app purchased once on the App Store. After purchase there are no further charges payable to the Operator, including in-app purchases, subscriptions, or model download fees. Prices may vary by region, and the price shown on the App Store is the amount charged.

Payment is processed by Apple and billed to your Apple Account. When you change devices or reinstall, you can download the App again at no extra cost with the same Apple Account. Your chats and cards are stored only on your device, separately from your purchase, so reinstalling does not restore them.

Refunds

Payments and refunds for the App are handled by Apple, so refund requests must be made directly to Apple under its refund policies and procedures. The Operator has no ability to view payment records or process refunds.

If a defect in the App keeps a feature from working, please let us know by email and we will do our best to find the cause and fix it.

AI-Generated Content

Character replies are fictional text produced probabilistically by a language model. They may be untrue, inconsistent, or not what you wanted, and the Operator does not warrant the accuracy, completeness, or fitness for any purpose of generated content.

Generated content is not professional advice, including medical, legal, financial, or mental health advice. For important decisions, always consult a qualified professional.

Because replies are generated only on your device, the Operator cannot see your chats and does not review or filter them. You are responsible for how you use generated content, including saving, sharing, or publishing it, and for the consequences.

Character Cards and User Content

Rights to the character cards you import or create and to your chat history belong to you or to the original rights holder of each card. The Operator claims no rights to them.

Import only cards you have the right to use. When you use a card made by someone else, follow its terms of use. You are responsible for the source, content, and rights of any card you import.

User Obligations

• Do not create or distribute cards or text that violate the law or infringe the rights of others.
• Do not create or store content that sexualizes minors.
• Do not use generated content to impersonate or defame real people, or to deceive or harass others.
• Do not reverse engineer, modify, or copy the App without permission, or bypass its payment.

Use of the model itself is also subject to the license described under Intellectual Property below.

Data Storage

All App data is stored only on your device. Your data will be permanently lost in the following cases, and the Operator cannot help recover it.

• You delete the App
• You reset, lose, or damage your device
• You switch to a new device without a device backup

The App offers no built-in backup or cloud sync. Please protect important chats and cards with a device backup such as iCloud Backup. Model files are not included in backups and need to be downloaded again after a restore.

Intellectual Property

Rights to the App's software, design, trademarks, icons, and the character cards bundled with the App belong to the Operator or their rightful owners.

The Gemma models are released by Google under the Apache License 2.0. They are listed, together with the open source software the App uses, on the Open Source Licenses page.

Changes to and Discontinuation of the Service

The Operator may improve or change the App's features, release new versions, and change the supported models or the repository models are downloaded from. If operating the App becomes difficult, the Operator may stop distributing and updating it, with advance notice.

Even if distribution stops or model files can no longer be downloaded from the external repository, the installed App, models already on your device, and your saved data remain and can continue to be used.

Limitation of Liability

The Operator is not liable for damages caused by events without its intent or gross negligence, such as natural disasters, device failures, operating system issues, or outages of the external repository, or for damages arising from the use of generated content. Where the Operator is liable, its liability is limited, to the extent permitted by law, to the amount the user actually paid for the App.

Governing Law and Disputes

These terms are governed by the laws of the Republic of Korea. If a dispute arises regarding the App, the Operator and the user will negotiate in good faith to resolve it. If no agreement is reached, either party may bring suit in the competent court under the Korean Civil Procedure Act.
