◍ Free Beta

Privacy Policy

Last updated — 2026-08-11

Mokchee ("the App") is a macOS desktop application for work-pattern analysis, provided by independent developer Kazuma Shimauchi ("the Developer"). This policy explains what data the App handles and how it is protected.

The App is currently a free beta released for value validation. A paid version is planned for the future.

§01

Local-first by design

The App stores all collected data only in a local database (SQLite) on your Mac. The Developer operates no server, and never views, stores, or collects your data.

Sensitive information such as API keys is encrypted and stored in the macOS Keychain via the safeStorage API.

§02

Data we collect

The App collects the following data on your Mac only, and stores it locally.

2.1 Activity data

Active window's app name and window title (every 5 minutes)
(Only when screen analysis is enabled) Text extracted from screenshots

2.2 Google Account data (only if connected)

If you explicitly connect a Google account, the App retrieves the following information in read-only mode. It never edits, deletes, or sends anything on your behalf.

Gmail: number of sent/received messages, correspondents, subjects, dates (gmail.readonly)
Google Calendar: number of meetings, attendees, titles, recurrence (calendar.readonly)
Google Drive: file names, action types, timestamps (drive.readonly, drive.activity.readonly)

2.3 Email address

We may collect your email address for the following purposes:

To register and communicate with you as a free beta participant
To send progress updates about data collection (1, 3, and 7 days after you start)

Your email address is not used for any purpose other than those above, and is never shared with third parties.

§03

Data sent to AI providers (Bring Your Own Key)

The App generates reports using your own API key (Anthropic Claude or OpenAI ChatGPT) — a "Bring Your Own Key" (BYOK) model.

When generating a report, locally aggregated activity data is sent to the AI provider you selected (Anthropic or OpenAI), through the API key you configured.
API usage fees are billed directly to you by the AI provider, based on your own contract with them. The Developer does not collect, mark up, or otherwise handle this fee.
The Developer cannot access the API key you enter. It is encrypted and stored in the Keychain, and used only to communicate with the AI provider.

⚠ If you enable screen analysis, screenshots of your screen are also sent to the AI provider. This may include the content displayed on screen (email bodies, documents, chat content, etc.). We recommend keeping this feature off when working with sensitive information. Screen analysis is off by default and only runs if you explicitly enable it.

§04

Deletion and disconnecting

Uninstalling the App deletes all locally stored data.
You can disconnect your Google account at any time from the Dashboard.
Screen analysis can be turned on or off at any time.

§05

Google user data

The App's use of Google Workspace APIs (Gmail, Calendar, Drive) complies with the Google API Services User Data Policy, including the Limited Use requirements. Google user data obtained by the App is never used for any purpose other than providing the App's work analysis and report generation features.

§06

Regional scope

This service is primarily intended for users in Japan. If you reside in a region where the EU General Data Protection Regulation (GDPR) applies, the service is not currently intended for your use.

Data sent to AI providers (Anthropic, OpenAI) is processed on their servers, primarily located in the United States.

§07

§08

Changes to this policy

This policy may be revised as features are added or changed. Significant changes will be announced within the App or on this page.
