Privacy Policy

Effective date: 9 June 2026 · Last updated: 9 September 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 contacts no server of ours at all — not for your purchase, not for anything else. Your purchase is verified through Apple, on your own computer. The only network traffic the app ever makes is 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: [email protected]. 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:

Your purchase: Kavaii is a one-time purchase managed by the App Store and verified through Apple, using Apple's own mechanism on your computer. The app does not contact our servers to check it. There is no licence key, no activation, no device fingerprint, and no periodic check — and nothing to renew, because it is not a subscription. Nothing about your purchase, your machine or your use of the app reaches us; because there is nothing to send, none of it exists on our side to be stored, requested or leaked.
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 [email protected] 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. Purchase and payment

Kavaii is sold through the Mac App Store. Payment is handled entirely by Apple. We never receive or store your card details, bank details, billing address, Apple Account or email address; Apple gives us only aggregated sales figures, from which no individual buyer can be identified. Apple's own privacy policy applies to the purchase.

6. How long we keep your data

We hold no personal data about you at all. There is no account, no licence record and no purchase record on our side — so there is nothing to keep, and nothing to delete. Everything Kavaii stores about you sits on your own computer and is described in the next section; you remove it by removing the app's folder. Records required for accounting are aggregated sales figures from Apple and contain no personal data.

7. Local storage on your device

Kavaii stores the following files on your own computer — on macOS inside ~/Library/Application Support/Kavaii/, on Windows inside %APPDATA%\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.

8. 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.

9. Children

Kavaii is not intended for children under 13 years of age. The App is rated 13+ in most countries, with a lower rating in a few; the rating displayed in your own store is the one that applies there. Kavaii does not knowingly collect personal information from children under 13. See our Terms of Service for details on eligibility and content rules.

10. 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 purchase is held by Apple under Apple's privacy policy: we receive no personal purchase data and hold no record about you. The only information that can reach us at all is a report you choose to email us. For that, you may contact [email protected] 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.

11. Where the data is

Nowhere but your own computer. We operate no server that your copy of the app connects to, so there is no database of ours holding anything about you.

Payments are processed by Apple, which is based in the United States, on the basis of the European Commission's standard contractual clauses used by that provider. Model downloads are made directly from your computer to Hugging Face, with no account or sign-in required, and do not pass through us. We do not transfer user content anywhere, because we do not have user content.

12. Security

All local files containing user data are encrypted at rest, and every network request the app makes uses TLS. Your conversations never leave your computer, so there is nothing on any server of ours that could expose them — that content simply does not exist outside your device, and there is no server of ours for it to exist on.

13. 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.
