Privacy Policy

Appligon Co., Ltd. ("the Company", "we", "us") respects the privacy of users of Kafkana ("the Service") and is committed to protecting personal information. This Privacy Policy explains the types of information we collect, how we use it, and how we protect it.

We may collect the following information:

• Account Information: Email address, display name, profile picture
• Authentication Data: Google, Discord, X (Twitter) OAuth integration data
• Usage Data: Chat history, character settings you create, records of generated images and videos, point usage history, and the content of support enquiries
• Technical Data: IP address, browser information, device information, cookies, and in-app activity logs
• Payment Data: Payments are processed by our payment provider (SUI PAYMENT). We never store credit card numbers. What we retain is the transaction record: date, amount, product, and transaction ID.

• Providing, operating, and improving the Service
• Generating AI chat responses, images, and videos
• Providing user support
• Detecting and preventing fraud and violations of our Terms (in particular, content depicting minors)
• Complying with legal obligations
• Sending service-related notifications

The core features of the Service are delivered using third-party AI APIs. As a result, the following information is transmitted from our servers to those providers:

• Chat: Character settings and recent conversation content are sent to a large language model (LLM) provider located in the United States.
• Image and video generation: Generation prompts (scene descriptions derived from the conversation) and reference images are sent to image/video generation providers located in Japan and Singapore.
• Voice features: The text to be spoken is sent to a speech synthesis provider located in the United States.

These transmissions do not include your name, email address, or payment information. What is transmitted is the conversation and generation content itself.

As a rule, we use these providers under contracts and published policies under which transmitted content is not used to train their models. If you would like more detail about the data protection regimes of the destination countries, please contact support.

By using the Service, you consent to the transmissions and cross-border transfers described above. If you do not consent, please do not use the Service.

All traffic is encrypted (HTTPS) and data is stored on access-controlled servers and storage. Chat data and generated content are managed in association with your account.

Other users of the Service cannot view your conversations or generated content.

However, our administrators may review that content in the following situations, limited to what is necessary to operate the Service safely:

• Responding to a support enquiry or investigating a defect
• Investigating a suspected violation of our Terms (in particular, content depicting minors)
• Reviewing quality reports you submit (👍 / 👎 feedback)
• Responding to a lawful disclosure request

In addition, as described in the preceding section, conversation and generation content is transmitted to third-party AI providers in order to deliver AI features.

The Service uses cookies and similar technologies for the following purposes:

• Essential Cookies: Maintaining login sessions, saving language preference and age confirmation
• Activity logging: We record in-app activity to understand which screens are used and how often. If you are signed in, these records are linked to your account (they are not fully anonymous). They are used only to improve the Service and are never shared with advertising networks.

You can disable cookies through your browser settings, but some features — including signing in — will not work.

We do not share your personal information with third parties except in the following cases:

• With your consent
• As required by law, or where necessary to protect life or safety
• With processors engaged to handle data on our behalf, limited to what is necessary

Those processors include: cloud hosting and database providers (United States), file storage (Japan region), an email delivery provider (United States), our payment provider (SUI PAYMENT), and the AI providers described in the preceding section.

We do not sell your personal information, nor do we share it for advertising purposes.

You can delete your account yourself at any time from your account settings page — no need to email support. Deletion erases your chat history, generated images and videos, characters, and profile information.

The following is retained, with the link to your name and email address removed:

• Transaction records (date, amount, product): Japanese tax law requires accounting records to be retained. These records contain no name or email address.
• Cancellation reasons you submitted: used for aggregate service-improvement statistics and containing no personally identifying information.

Data that we are legally required to retain is outside the scope of erasure requests under Japanese data protection law.

Note that if you have an auto-renewing paid plan, you must cancel it before deleting your account. This prevents a situation where the account is gone but billing continues. In that case the app will guide you to the cancellation flow.

Residents of Japan (Act on the Protection of Personal Information): You may request notification of the purpose of use, disclosure, correction, addition, deletion, suspension of use, erasure, or suspension of third-party provision of your retained personal data. Send requests to our support email; once we have verified your identity we will respond within a reasonable period.

Residents of the EU/EEA (GDPR): You have the following rights:

• Right of Access: Request access to your personal data we hold
• Right to Rectification: Request correction of inaccurate personal data
• Right to Erasure: Request deletion of your personal data
• Right to Restriction: Request restriction of processing your personal data
• Right to Data Portability: Receive your personal data in a structured format
• Right to Object: Object to processing of your personal data

To exercise these rights, please contact our support team.

This Service is intended for users aged 18 and above. We do not knowingly collect personal information from anyone under the age of 18. If you believe a minor has registered, please contact info@appligon.com. See our Age Verification Policy for details.

We may update this Policy from time to time. We will notify you of significant changes through in-service notifications or email.
