Effective Date: March 17, 2026
This Privacy Policy explains how Kizuki (“we,” “our,” or “us”) collects, uses, and protects information when you use our application.
By downloading, accessing, or using Kizuki, you agree to the practices described in this Privacy Policy.
Kizuki does not require you to create an account. We do not intentionally collect personal information such as your email address unless you contact us directly.
Depending on how you use the app, the following types of information may be processed:
We use information processed through Kizuki to:
If you choose to enter your name during onboarding, it may be used to personalize AI-generated content and messages shown within the app.
If you use AI-powered features, information such as your goals, struggles, mood check-ins, and reflections may be sent to our AI provider in order to generate personalized responses and insights.
Kizuki is designed to store much of your app data locally on your device.
Emotional check-ins, reflections, and similar wellness-related content are primarily stored on your device unless needed to generate AI-powered content within the app.
We use trusted third-party services to operate and improve Kizuki:
These providers may process information in accordance with their own privacy policies.
We may collect limited analytics and technical information to help us understand how Kizuki is used and to improve performance, reliability, and usability.
This may include:
We do not sell your personal information and do not use analytics data for third-party advertising.
Some Kizuki features use artificial intelligence to provide personalized reflections, supportive content, and wellness insights.
When you use these features, content you provide may be processed in order to generate a response. This can include your name, goals, struggles, mood check-ins, and written reflections, depending on the feature you use.
AI-generated content is created dynamically for your use within the app. While we aim to minimize unnecessary data handling, using these features means relevant input may be transmitted to third-party AI services for processing.
We do not sell your personal information. We only share information when necessary to operate the app, including through service providers that help us deliver subscriptions, analytics, diagnostics, and AI-powered functionality.
Because Kizuki does not require a user account, there may not always be a central profile for us to access or delete.
If you would like to ask a privacy-related question or request deletion of analytics-related data that may be associated with your device, you can contact us at hello@kizuki.app.
We will review requests in accordance with applicable law and our ability to identify the relevant data.
We do not knowingly collect personal information from children in violation of applicable law. If you believe a child has provided personal information through the app where it should not have been collected, please contact us and we will review the matter promptly.
We may update this Privacy Policy from time to time. When we do, we will update the Effective Date at the top of this page. Continued use of the app after any updated Privacy Policy takes effect means you accept the revised policy.
If you have any questions about this Privacy Policy or your data, please contact us at: hello@kizuki.app
