This Privacy Policy explains how we collect, use, store, share, and protect information in connection with the Services.

This Policy applies generally to our Services. The information actually collected depends on the particular Service and features that a user chooses to use.

1. Information We Collect

We may collect the following categories of information to the extent necessary to provide the Services.

(1) Account and Authentication Information

If a Service provides account functionality, we may collect information such as:

When an external authentication provider such as Apple or Google is used, we do not obtain the user's password for that provider.

(2) Content Created, Entered, or Uploaded by Users

Depending on the Service and features used, we may process content that users enter, send, save, or upload, including:

We use this information to provide features selected by the user, including storage, search, organization, synchronization, and AI processing.

When a user chooses to use a relevant feature, and after obtaining the permissions required by the operating system, our Services may access:

Such access is used only to provide features selected by the user, such as adding photos, image analysis, voice notes, or speech recognition.

(4) LINE Integration Information

For Kun and other Services that support LINE integration, when a user connects or interacts with the Service through LINE, we may receive or process information through APIs provided by LY Corporation or related LINE services, including:

We use this information to associate the LINE user with an account in our Services and to provide functions such as saving notes, AI processing, organization, and search.

We do not independently access a user’s LINE friends, unrelated chat history, or other information that the user has not sent or authorized for use with our Service.

(5) Calendar Information

If a user enables a calendar integration feature, we may access calendar information on the device or through external services such as Google, within the scope authorized by the user.

This information may include:

This information may be used to display, create, search, associate, or remind users about calendar events.

We seek to access only the calendar permissions necessary to provide the selected feature.

Users may disable notifications through their device settings.

For purposes such as delivering advertisements, limiting ad frequency, measuring ad performance, and preventing fraud, advertising providers may collect or process information such as:

The information processed may vary depending on the advertising provider, the user's region, device settings, consent status, and advertising preferences.

(10) Purchase and Subscription Information

3. AI Features and Processing

The Services may provide AI-powered functions including text generation, question answering, summarization, classification, search assistance, image analysis, speech recognition, recipe suggestions, and other features.

To provide these features, some or all of the text, images, audio, or other content submitted by a user may be transmitted to external AI service providers or APIs.

We seek to transmit only the information reasonably necessary to provide the requested functionality.

The retention period, processing location, use for model improvement, and other processing practices of external AI providers may vary depending on the provider, contractual terms, API configuration, and settings used by BAUAI.

Users should avoid submitting highly sensitive information to AI features when such information is not necessary for the requested function.

4. Advertising and Tracking

Some of our Services may use third-party advertising services such as Google AdMob.

Advertising providers may process certain device and usage information for purposes such as ad delivery, measurement, frequency control, and fraud prevention.

BAUAI does not sell users' personal information.

Where personalized advertising or other processing constitutes “tracking” under applicable law or platform rules, such processing will be conducted subject to applicable consent requirements, device settings, and platform requirements.

On Apple platforms, if a data practice requires permission under Apple’s App Tracking Transparency (“ATT”) framework, we or the relevant integrated SDK will follow Apple’s applicable permission requirements.

Users may be able to manage advertising preferences through device settings, Apple or Google advertising settings, or consent controls made available within a Service.
