Privacy Policy

App: Kotori (One-Line Expenses)
Developer: kicucya

This Privacy Policy applies to Kotori on iOS.

Data Processing

Kotori does not upload your financial data to the developer's servers.

Everything you record is processed locally on your device:

iCloud Sync

If you enable it, your ledger syncs across your own devices through your private iCloud account (Apple CloudKit). This data lives in your personal iCloud; the developer cannot access it.

Microphone & Speech Recognition

The microphone is used only while you are actively recording an entry. Audio is used for on-device speech recognition and is not sent to the developer.

Diagnostic Logs

Kotori can record diagnostic logs to help investigate problems with the app. This is off by default, and recording starts only after you turn it on yourself inside the app.

Diagnostic logs never grow without bound. They are capped in size (roughly 1–2 MB in total), and once the cap is reached the oldest entries are replaced by newer ones. No third-party crash-reporting or analytics SDK is included for this feature.

Third-Party Advertising

Kotori may display ads through Google AdMob where available. Google may collect:
