Privacy Policy

Effective date: 9 June 2026 · Last updated: 29 June 2026

Short version. Kavaii runs entirely on your computer. We do not collect, transmit, or store the content of your conversations, your voice, your camera frames, or any text you write inside the app. There is no telemetry, no analytics, and no behavioural tracking. Kavaii does not connect to any servers of ours. The only network traffic is your subscription, which is managed by the App Store, a one-time, anonymous download of the AI model from Hugging Face (no account needed), and any report you choose to email us.

1. Who we are

Kavaii is published by Systana LLC, a company registered in Georgia. Contact: kavaii@sistana.ge. For data protection enquiries please use the same address with the subject line "Privacy".

2. What Kavaii is

Kavaii is a fully offline 3D anime simulation application. All conversational AI inference, voice synthesis, voice recognition, and image understanding happen locally on your computer, using models downloaded to your device. No conversational content is sent to any server operated by us or by a third party.

3. Information we do not collect

We do not collect, store, transmit, log, sample, analyze or share any of the following:

The text of your chat messages, in either direction.
Audio captured by your microphone (Free-Flight voice mode).
Transcripts of audio captured by your microphone.
Images or video frames captured by your camera or attached to messages.
Custom prompts, persona content, or other character configuration.
Names you give your character or other display-only labels.

These remain exclusively on your computer, stored locally inside Kavaii's application support directory. Chat history and settings are encrypted at rest on your device.

4. Information we do collect

First, the absolute promise: Kavaii has no telemetry, no analytics, and no behavioural tracking, and it never transmits the content of your conversations, your voice, or your camera or attached images — not to us, and not to any third party. The only way we ever learn about a problem is a report you choose to email us.

The only network activity Kavaii makes is the following, and nothing else:

Subscription: your subscription is managed by the App Store, and your purchase is verified through Apple. The app does not contact our servers to check your subscription.
Model download: the list of available character brains is built into the app, so Kavaii does not contact our servers for it. When you choose a brain, the app makes a standard one-time HTTPS request directly from your computer to Hugging Face, the public registry where the model files are hosted. No account, sign-in, or registration is required — the download is anonymous. It goes straight from your computer to Hugging Face; it does not pass through us, and Hugging Face's own privacy policy applies to that request.
Reports you send voluntarily: if you use the "Report a safety issue" feature, the app drafts an email to kavaii@sistana.ge with the text you write. Nothing is attached automatically and no chat content is included; anything you decide to paste into the report is your choice. This voluntary email is the only way we ever hear about a problem.

5. Local storage on your device

Kavaii stores the following files on your Mac, inside ~/Library/Application Support/Kavaii/:

Your chat history — stored encrypted.
Your settings — stored encrypted.
The AI model files you have downloaded.

You can delete these files at any time by removing the Kavaii/ folder, which permanently erases your local data.

6. Cookies, analytics, telemetry

Kavaii does not use cookies, advertising identifiers, analytics SDKs, crash reporters that include user content, usage tracking, or any form of behavioural telemetry. We do not track what you do inside the app.

7. Children

Kavaii is not intended for users under 18 years of age. The application requires you to confirm that you are an adult before first use. See our Terms of Service for details on eligibility and content rules.

8. Data subject rights (GDPR)

Because we do not collect conversation content, most data subject rights under the GDPR are satisfied by the architecture of the application itself: there is nothing on our side to access, rectify, port, or erase.

Your subscription is managed by the App Store, so we do not hold your payment or subscription records — those are handled by Apple under Apple's privacy policy. For any limited information that may reach us (for example, a report you choose to email us), you may contact kavaii@sistana.ge to exercise your rights of access, rectification, erasure, restriction of processing, data portability, and to object to processing. You may also lodge a complaint with your local supervisory authority.

9. International transfers

Your subscription is managed by the App Store. Model downloads are made directly from your computer to Hugging Face, the public registry where the model files are hosted, with no account or sign-in required. We do not operate servers that your copy of the app connects to, and we do not transfer user content because we do not have user content.

10. Security

All local files containing user data are encrypted at rest, and the model download uses TLS. Your conversations never leave your Mac, so there is nothing on any server of ours that could expose them — that content simply does not exist outside your device.

11. Changes to this policy

We may update this policy as the product evolves. Material changes will be announced in the application and on this page. Continued use of Kavaii after a change constitutes acceptance of the updated policy.
